Wake County, Triangle Transit, Capital Area Metropolitan Planning Organization (CAMPO), City of Raleigh, Town of Cary, Research Triangle Foundation, NC State University and Raleigh Durham Airport are partners in planning transit..
It’s Wednesday, and we have another rider profile to share. This week we are hearing from Kathy who lives in Fuquay-Varina. She uses transit to get to the community center and to run errands.
Name: Kathy Cox
Town you live in: Fuquay Varina
Twitter handle: Sorry, I don’t do twitter or any other social media
How often do you ride transit? Monday through Friday
Where do you ride to/from? Fuquay Varina Community Center and sometimes the Hilltop Food Lion Plaza in Fuquay Varina, if I have errands to run at the north end of town.
Why do you choose transit? Riding the bus gives me almost 2 hours of personal time. I read a book, write letters and even pay bills during the ride. I enjoy starting and ending my work day without the stress of driving in rush hour traffic.
– What do you like best? The personal time to gear up and unwind from the work day.
– Any downfalls? Schedule delays due to faulty equipment or lack of drivers. We have lost several riders because they just don’t feel like the service is dependable. Consistent on-time routes have to be a priority for bus transit or folks will simply get back into their cars to get to work on time and leave on time.
If transit wasn’t available what would you do? Would others be impacted? I would return to a van or carpool.
If rapid transit were available (rail or bus) how would it change the way you move through the community? It would entirely depend on where the terminal locations were. I would try to use it as much as possible.
Have you read the Expanded Transit Choices Report? Yes, I have.
What is something you learned from the report that you didn’t know before? The issue of how to balance ridership versus coverage. I am all about coverage for Wake County and the Triangle.
Anything else you would like to add? I very much appreciate the efforts being made by all the municipalities and transit authorities in Wake County and the Triangle to come up with transit solutions. In the short term I do think buses, that run consistent on-time schedules, and bus lanes could get more cars off the road quickly. Thanks for letting me participate.
Jarrett Walker, one of the consultants assisting us with our Transit Strategy, created the below blog post about the “Ridership Recipe.” This post, also published on his Human Transit blog, relates directly to Wake County as we contemplate the four alternatives, and in particular the tradeoff between focusing resources on ridership or coverage.
When transit is planned with the goal of high ridership, what does that mean? When you tell network designers like me to maximize ridership, what do we do?
Maximizing ridership is like maximizing the number of customers for any business. You have to think like a business, and the first thing businesses do is choose which markets they will enter. Unlike governments, businesses feel no obligation to provide their service in places where they would spend a lot of money to serve very few people.
(Businesses also want customers to pay more rather than less, but for our purposes here let’s hold fares or prices constant, and just think about how you get lots of customers.)
Everyone understands that McDonalds is a business, which means it is under no obligation to provide a burger restaurant within 1/2 mile of every citizen. If they were, every ranch (population 4) in North Dakota would need to have its own McDonalds at the end of the driveway. Obviously the company would go bankrupt staffing all of these shops dotted across the prairie, miles from the nearest town, each with a smiling team waiting (and waiting, and waiting) for a customer to appear.
So in the real world of business, a rancher in North Dakota may have to drive 50 miles to find a McDonalds, because the only one will be in a large town where there are enough customers. We don’t describe this situation as McDonalds being unfair to rural folks, because we know McDonalds is a business doing what businesses do. Businesses deploy their product or service where it will succeed.
Commentators sometimes criticize transit authorities for low ridership, as though transit were a failing business. But transit authorities are rarely directed to maximize ridership as their primary goal, so they’re not failing if they don’t. In democracies, whoever makes the decisions for a transit authority is accountable to voters. These officials listen to their constituents, and sometimes decide that to some degree, low-ridership services are necessary and important. This is usually because either (a) someone feels entitled to service (“We pay taxes too!”) or (b) someone needs the service really badly (“If you cut this bus, we’ll be trapped.”). Those can both be valid government purposes, but they lead to the creation of services where ridership is not the objective. The objective, instead, is to satisfy (a) and/or (b) above.
Services whose purpose is not ridership are called coverage services — or at least I’ve been calling them that for over a decade and the term is catching on. Coverage is an apt term because the result is usually to spread out service over a vast area so that everyone gets a little bit, no matter where they live.
However, spreading it out means spreading it thin. Any fixed service budget, divided over such a huge number of routes, yields low frequency, maybe a bus once an hour, and not many people find that useful for reasons we’ll explore below. So ridership is usually low on these services, exactly as we network designers expect. But since ridership isn’t the purpose, that can be fine.
So you will not begin to make clear transit choices until you are clear, at every moment, about whether you want transit service to have high ridership. To the extent that you do, you need to tell transit agencies to think like businesses, which means deploying the service not where people feel entitled to it, or where they need it badly, but where the maximum ridership will result. On the other hand, if you do want to respond to people’s expectations and needs, you need to carve out an exception to your desire for high ridership, because high ridership is not, in fact, what you’re advocating.
Did you just hear me say that we should deploy transit service for maximum ridership. If so, read the last paragraph again. There is no “should” in that paragraph. There is only a description of the consequences of choices that you, and your community, are free to make.
It’s not a yes-or-no question, of course. A more precise question is: “what percentage of our resources should our transit authority spend pursuing maximum ridership?” When transit authorities answer that question, then everyone knows what the purpose of the service is. The services that are trying to attract high ridership can be assessed for their ridership, and the coverage services, where ridership isn’t the goal, no longer count as failing because ridership is not what they’re trying to do. In our network redesign for Houston, for example, the Board said “deploy 80% of our budget pursuing ridership.” That’s what the plan does. We know which lines in the New Network are intended for high ridership, and those are the ones where we’ll expect that outcome. (For my peer-reviewed academic paper on this issue, see here.)
So for now, I’ll suppose that you do want a ridership-maximizing transit system. What does that look like? How do we network designers know that we’re designing one?
First, you really must understand transit frequency. It’s the elapsed time between consecutive buses (or trains, or ferries) on a line, which determines the maximum waiting time. People who are used to getting around by a private vehicle (car or bike) often underestimate the importance of frequency, because there isn’t an equivalent to it in their experience. A private vehicle is ready to go when you are, but transit is not going until it comes. High frequency means transit is coming soon, which means that it approximate the feeling of liberty you have with your private vehicle – that you can go anytime. Frequency is freedom!
At the opposite extreme, if you live in a single family house with a driveway and usually get around by car, imagine that there were an automated gate at the end of your driveway that only opened once an hour, on the hour. When it’s closed, you can’t get your car in or out. If that were your situation, your biggest transportation problem would not be traffic congestion, or how fast you can go on the freeway; it would be how to get this frigging gate to open more often. That’s how low frequency feels to a potential transit customer, and why frequency often swamps other factors, like speed, in determining whether transit is actually useful.
Frequency has three independent benefits for the customer, which helps to explain why high frequency is so critical to sustained high ridership:
It reduces waiting, which is everyone’s least favorite part of a trip. (No, a smartphone that tells you when the bus comes doesn’t solve the problem of waiting; we are still talking about time when you’re not where you want to be.) The basic sensation of being able to go when you want to go is the essence of frequency.
It makes connections easy, which makes it possible for a pile of transit lines become a network. In transit, this is huge. A transit line without good connections is useful for travelling in one dimension, along that line. A network of frequent lines makes it easy to travel in two dimensions – all over the city, or at least all over the part of it that supports frequent service. This network effect massively expands the usefulness of every line in the network, thus increasing each line’s ridership potential.
Finally, frequency is a backstop for problems of reliability. If a vehicle breaks down or is late, frequency means another will be along soon.
If you think about how these three things govern the real usefulness of transit, you can begin to see why frequency is such a ridership-driver. Here’s a simple scatterplot with a dot for each bus route in a whole bunch of US agencies where my firm has worked. Note that higher frequency (leftward on the X axis) correlates with high productivity (ridership per unit of service cost).
This is more amazing than it looks. Double the frequency of a line and you’ve doubled its operating cost, so you would expect high frequency to pull productivity down. And indeed, if you do that to a particular line at a particular moment, it usually does.
But overall and in general, high frequency correlates with high productivity, despite the high cost of the frequency. That’s because (a) frequency is such a powerful ridership-driver for the reasons outlined above and (b) frequency tends to be deployed where it will succeed.
How do we identify those places? Stay tuned.
Finally, the duration of service matters, and it works much the way frequency does. Service later into the evening, or on weekends, initially appears to be a bad investment, because we’re adding lots of service when there aren’t as many riders. But in the long run, its availability tends to correlate with high ridership. That’s because riders won’t use the service in one direction unless they can get back, so evening service, even if the buses aren’t full, is a key part of how we build high ridership all day. The same is true of weekends. If you commute five days a week including some weekend days – like many people in the retail, entertainment, or service sectors – you are unlikely to rely on transit unless it works for you on all of those days. One of the key features of our Houston redesign is bringing weekend service up to the same level as weekdays, so that except for the weekday rush hour, the bus comes the same time every day.
Diversity, Not Specialization
How do we network designers know where transit will succeed? You might assume that this is about detailed demographic analysis, detailed studies of travel behavior, and lots of conversations with citizens, finding out who people are and exactly what their needs are.
Well, we do a lot of that, and the data is interesting and helpful in resolving many details of a network plan. But in the end, it’s less important to high-ridership planning than a simpler question: “Where can we find lots of people, and places where lots of people are going, located in ways that are cheap for us to serve?”
The most successful transit, in terms of ridership achieved for a fixed operating budget, is called mass transit for a reason. They succeed precisely because they are not designed around the details of anyone’s needs. Riding them — a big city subway system, for example — you will not get much assurance that planners of the system understand you in particular, or know what trip you’re making now, or care much about your unique point of view. Instead, you’re likely to notice how many different people are finding the same vehicle useful. You’re likely notice diversity. We’ll come back to that.
At the opposite extreme, if you use a suburban or small town bus that never has more than five people on it, you may get very personal attention. The driver may even remember your name. But that charming fact is made possible by how low the ridership is.
As transit ridership potential goes up, responsiveness to each individual’s needs and desires goes down. The big-city subway doesn’t take care of your personal needs, but that’s inseparable from why it’s massively liberating to so many people.
It’s flattering to us, as individuals, to think that if transit just specialized more – just took better care of me or people like me – it would have higher ridership. That’s why we hear so much about it in the media — because it’s what we want to hear.
But specialization is simply not how the transit product succeeds at attracting great masses of people. Transit achieves high ridership by being useful and liberating to lots of people, not to any particular kind of person. High ridership arises from diversity, not specialization.
There are small exceptions, which happen when a large number of people are all doing the same thing at the same time. A big suburban school lets out at 3:00 PM, or the ball game ends at the stadium, or white-collar workers all want to get from an outer suburb to downtown at 8:00 AM. The “peak only” column in the scatterplot above shows some of those. But these exceptions are always about brief periods of time. What I’ve been talking about, everywhere but this paragraph, is the kind of ridership that’s sustainable all day and all week, and that supports continued growth into evenings and weekends to support an “18-hour” or even “24-hour” city. Specialization by time of day can fill some transit vehicles, but it’s a vastly smaller market (and a more expensive one to serve) than the kind of demand that’s happening all the time.
So Where Should We Run?
So to the extent that a transit authority is seeking sustained high ridership across long hours, it would focus its most powerful-but-expensive tools, high frequency and long duration, in the places where they can succeed.
Where are those places? Like any business, we need to put the service where
(a) there are lots of potential customers.
(b) those customers will be able to access our service easily and
(c) our costs of providing service are not too high, compared to the number of customers we’ll attract.
Now, let’s think about the high-ridership transit product. It’s simplest unit is a line or route with a number of vehicles running back and forth along it.
The cost of providing the service is based on the number of transit vehicles running along it (let’s call them buses, but all this is the same for trains or ferries as long as each one has employees on board. This number goes:
Up with frequency. Double how often a bus comes, and you’ve doubled the number of buses on each mile of the line, doubling the cost.
Up with distance. Double the length of the line and you’ve doubled its cost.
Down with speed. Double the speed of the service, and the buses take only half as long to cycle the line as they did before, so you need only half as many of them to deliver the same service. You’ve halved the cost.
For now, let’s hold frequency and speed constant, and focus on distance. The key question for high-ridership transit, then, is “how far do we have to go to be available to a given number of people?” This is transit’s version of the question any business asks about a particular venture, like opening a shop in a particular place: “How much will it cost to be useful and attractive to an adequate number of customers?”
In transit, the answer is: It depends on the pattern of development, and especially on four measurable things:
Let’s look at each in turn.
The image below shows two towns and a transit line running through them. The transit line in the two images is identical, so it has the same cost. But in the first town, the line is available to twice as many people, because the town is twice as dense. That means that if everybody in both towns had the same propensity to use transit, ridership would be twice as high on the first route as on the second. Since the costs of the two services are the same, the top town is twice as good as an investment for the transit agency.
It really is that simple. Density means that any given service investment is useful to more people, so of course it attracts more riders.
In fact, density is more powerful than that. In this image I contrast two neighborhoods where everything is the same except that one is twice as dense as the other. But in fact, this difference in density generates other important differences that also tend to increase ridership. Parking is more difficult or expensive, and because more things are in walking distance, people are more likely to walk or cycle short distances. People without cars (because they can’t drive, or can’t afford one, or simply don’t want one) also logically choose to locate in higher-density areas where transit, walking, and cycling are easier, and this further reinforces the ridership from these higher density areas. So in many cases, we find that the difference in ridership between these two towns is more than double. It’s double just because there are more people, but in addition, each of these people is also more likely to use transit, because of these other factors that also track with density.
So can we get high ridership out of low density ? Only if we can create artificial density of demand around a transit line or stop. Park-and-Ride, for example, is a way to get people from a low-density area to gather, densely, around a transit station, so that they justify intense service. Park-and-Ride raises other challenges because of the space it takes, but there is a huge range of potential non-transit solutions for giving people ways to get to a transit station, including bike-and-ride, roles for private sector demand-responsive service, and others. From the customer perspective these are called “last mile” solutions. But for a ridership-mazimizing transit authority, these are ways of creating the density of demand, at a transit stop, that makes good service viable, even though that density is not present in the land use.
In the drawing about density I assumed that people could walk to the transit line easily, but that’s not always true. The local street network, and the design of the street that transit runs on, determine whether it’s possible to get to the service. People who can’t get to the service aren’t going to be riders, so this impacts ridership directly.
In this diagram, the two circles on the left have a gray dot in the center, representing a transit stop. The circle is the area that is within a reasonable crow-flies distance of the stop (say 1/4 mile, but it doesn’t matter what you think this distance is).
The circle is a very crude measure of the area where people might find this transit stop useful. However, if you are only willing to walk a certain distance, say 1/4 mile, then the real limit is how far you can walk along the available streets and paths. The streets shaded in black indicates the parts of the neighborhood that are within 1/4 mile walk of the stop, not just 1/4 mile by air.
The local street network makes all the difference. In the neighborhood on the left, the gridded street pattern puts about 2/3 of the circle within walking distance, while the disconnected suburban street pattern on the right puts only 1/3 of the circle within walking distance.
So if all other things are equal, including density, the neighborhood on the right will have half the ridership potential as the one on the left. That means that a transit agency focused on ridership will deploy much more service to the neighborhood on the left than to the one on the right.
Another important dimension of walkability is whether you get to the transit stop in the correct direction. When transit runs on a major street or road, the stops in the two directions of travel are on opposite sides of the road. If you want to make a round trip by transit, you will leave from one side of the road in the morning and be dropped off on the other side in the afternoon. So it has to be possible to cross the road, as a pedestrian, at the stop.
Again, if this is impossible, because there are no signals or other crossing provisions near the stop, then you should expect a ridership-maximizing transit planner to run less service. Some transit professionals argue that transit should never stop where it’s not safe to cross the street, because when pedestrians are hit by cars in this situation, the transit agency is sometimes held liable for having put a stop in an unsafe location.
In the image below, two towns are made up of the same four centers of development. Maybe one is a college, one is a shopping center, one is a mass of apartments, or whatever. In any case, the two towns are identical except for the locations of the four centers.
In the first town they are in a reasonable straight line along a path that transit can follow. That means that a single transit line connects all four centers, in a way that feels reasonably direct for travel between any two centers.
In the second town, a single line connecting all four centers is maddeningly circuitous, and therefore much less attractive if you’re traveling between centers that are not adjacent. There would be another solution for the second town, which is to run a direct bus route between each pair of centers, bypassing the others. But that’s more route-miles, and hence less frequency and duration of service for a given service budget, and hence service that’s less likely to be useful to many people.
Putting development at the end of a long cul-de-sac makes it a worse prospect for ridership, which means a ridership-maximizing transit agency will give it less service. Remember: if you want good transit, locate “on the way” between other places that support good transit.
Finally, notice that you can create the same problem by slowing down a transit service, as road-dieters, traffic-calmers, and bike-lane advocates often inadvertently do. Look at the first town, but now imagine that the two centers in the middle of the line have slowed down the transit service as it runs through them. For ridership, this has exactly the same effect as the layout of the second town: it turns the middle centers into obstacles to travel between the outer centers, discouraging the use of transit for travel between them. (The outer centers will demand an express bus to get around the obstacle, but again, solving the problem with more lines means you can afford less frequency, so service is less useful, so ridership will be lower.)
In this image, two towns are identical except for the distance between the main residential area and the main business area. Longer transit lines cost more to run than short ones, so in the second town it will cost more to serve the same number of people. If a transit budget is the same in the two towns, the second town will have less frequent service or service for a shorter duration. That’s because the same resource is spread over more route miles, yielding less frequency. That, in turn, means lower ridership.
Summing It Up
If you come from a neighborhood that looks like the second town in one of these drawings, how did you react to these images and explanations? Did it sound like I was criticizing your home, or saying you shouldn’t have transit service?
No, those would be aesthetic or moral judgments, and that’s not my job. My job is to explain the how transit is designed if high ridership is the goal. I’m not saying that ridership should be the goal – a moral judgment again – but only that if it’s the goal, this is what transit would logically do. It would look for markets that offer density, walkability, linearity and proximity, and focus excellent service there. Where those features are absent, it would recognize that ridership potential is lower regardless of the service provided, so it would deploy little or no service.
This is how businesses behave, by choosing the markets they will enter, based on where the conditions are right for them to excel. Do you want transit to carry as many people as possible? To what extend do you want that? That’s up to you, and your community.
This Friday we have just two questions. Both have come up frequently as we’ve been out and about in the community.
1. How do the alternatives mesh with land use?
The two ridership alternatives (both Bus Rapid Transit and Rail Rapid Transit) serve the densest parts of the County with higher frequency service, where it is assumed that ridership would be highest. The two coverage scenarios serve a wider area of the County with lower frequency service, where it is assumed that while ridership may be lower, more citizens throughout the County would have access to transit.
All four alternatives provide service on the corridor between Research Triangle Park and downtown Raleigh, where planning for transit-oriented development (generally higher density residential and mixed use development) has occurred. All scenarios also provide some level of service between many of the outlying towns in the County, where a lot of lower-density housing is located, and Raleigh and/or Cary.
2. How do the various options impact private vehicle use? Bus lanes v. general use lanes?
At this time, it is hard to say for certain how the various options could impact private vehicle use. The rail transit lines in the Rail Rapid Transit (RRT) scenarios should not have much of an impact on private vehicle use, since the transit lines would be within the existing railroad corridors; however there may be some impact at existing at-grade crossings due to the higher frequency of trains in the corridor.
The proposed bus corridors in all four scenarios may include some conversion of existing general use lanes to bus lanes, particularly along the Bus Rapid Transit corridors in the two BRT scenarios, but that would be determined once the plan is adopted. If the final adopted scenario includes a BRT corridor, part of the planning and permitting for any BRT corridor would include an evaluation of the impact of converting any existing general use lanes to bus lanes, and that impact could be required to be mitigated.
If you have a question, comment on this blog post or drop us an email (email@example.com) or stop by one of our events. There are MANY scheduled. To find one that works for you, head over to the www.waketransit.com/meetings.
This week our Friday questions are all related to Research Triangle Park (RTP). We’ve held a few events out that way recently, and wanted to use today’s post to share some of the most frequent questions from those who work or frequently make the trip to RTP.
1. In the four scenarios that are currently being discussed, two show rail going to RTP. If this is the case, which corporate headquarters will have stops?
In the rail scenarios, Rail Rapid Transit is shown extending as far as NC 54 and Miami Boulevard (Durham County) in Research Triangle Park. This is an undeveloped property that is being reserved by RTP for transit-oriented development. No corporate headquarters are located there today, however, the property is in close proximity to several major employers. The proposed rail terminus is also within a mile of the Park Center, a major mixed use district soon to be constructed in RTP. The transit-oriented development areas would become the centers of RTP based transit services since employees and employers would need access to these locations for multiple reasons (meeting space, dining, etc.).
2. How do you expect RTP workers to get from a transit stop to work? Have you talked with any large employers about offering a shuttle?
Future services have not been planned in detail. RTP companies are involved and will stay engaged with the transit planning process, hearing updates progress and trade-offs and offering feedback through various channels. By and large, employers recognize the value of a robust transportation infrastructure that includes transit and they understand the specific challenges of transit in RTP. RTP employers have discussed the potential of operating shuttles and/or working together to fund shuttle service that would connect to the major transit corridors. The approach used today involves a series of shuttles operated by GoTriangle and several large employers. These connect various campuses to our regional bus station. Many RTP companies also have travel demand management programs in place which encourage employees to use alternative commuting modes (transit, carpooling, biking, etc). Enhanced transit service will benefit these programs.
3. How will this project work with major RTP corporations such as Cisco, IBM, etc. in planning efforts…. Especially in the way to attract more talents to the RTP area?
RTP companies have remained engaged with this process since the beginning, hearing updates on the Transit Choices Report and transit plan options, and offering feedback through various channels. By and large, employers recognize the value of a robust transportation infrastructure that includes rapid transit. This supports them in recruiting and retaining the best talent. Many RTP companies have travel demand management programs in place which encourage employees to use alternative commuting modes (transit, carpooling, biking, etc). Enhanced transit service will benefit these programs, making our companies more attractive places to work.

We’ve been getting great feedback on the questions and answers we’ve posted the last three Fridays. Including some more questions. We’ve answered several below and plan to have more for you next week. If you have a question, please post it in the comments to this post, email it to firstname.lastname@example.org or connect with us @WakeTransit on Twitter.
1) For those trips other than non-peak, what would be hours of service?, More buses?
Figure 3: Service Types Table on page 11 of the Expanded Transit Choices report provides details about span of service for all types of transit modes proposed in this plan.
While specific start and end times will not be proposed in the Wake Transit Investment Strategy, the plan proposes 6 hours of weekday peak service for every route regardless of technology (approximately 3 hours in the AM and 3 hours in the PM). The weekday base period will last roughly 9 hours for every route except 60-minute routes (8 hours), and evening span ranging from 2-5 hours. With the exception of peak-only routes the span of service for most routes in the system will range from 18-20 hours a day, a significant increase from present.
Under this plan Saturday spans will largely mirror weekday service (18-20 hours for most routes) and Sundays will be slightly less (17-18 hour). In both cases, every route will have Saturday and Sunday service, a major change to present services, and routes will run much more frequently and longer during the day.
2) Why does rail stop at 440?
Rail service stops at I-440 primarily because the plan was unable to identify enough revenue resources to pay for infrastructure and service investements during the 10-year plan horizon. This is part of the reason why the rail segment north from downtown Raleigh to I-440 will only operate at 30 minute headways rather than 15 minutes as proposed for the segment between downtown Raleigh and the Research Triangle Park. A future plan update may identify the need to extend the rail line beyond I-440 to the north, improve headways to 15 minutes or both.
3) As BRT routes circular (GORaleigh 12) or out and back style?
It is preferred that major transit corridors follow a linear path with bi-directional service. This is the preferred alternative for all corridors with major investment. The only exception may be the end of the line where a terminus point for the route is needed.
4) How will downtown Raleigh be impacted with future expansion of bus service?
Several questions this week are related to bus service in Raleigh. Remember, the name of the current service recently changed to GoRaleigh.
Downtown Raleigh will have an increase in bus service in all scenarios; however, some routes may route through the urban core in lieu of using a centralized transit hub such as the current Moore Square. The final details associated with routing in the urban cores of Raleigh and Cary will be defined once a final alternative is selected.
5) Why is the S. Saunders BRT only in the coverage alternative? Why does the Capital BRT stop so soon outside downtown?
The segment added along Wilmington and South Saunders Streets between downtown Raleigh and Garner is added to the coverage scenario and not the ridership scenario because investment in this corridor won’t yield high ridership results but will help improve travel time and reliability for local and express bus services from the rest of Wake County and which will benefit from being trunked along this corridor. The Wilmington / South Saunders BRT corridor would likely yield similar results under the BRT – Ridership scenario but due to resource prioritization constraints there isn’t revenue available to implement this particular project within the 10-year plan horizon.
Two weeks ago we started answering your questions about the Wake County Transit Strategy on Friday. This Friday, we’ve got more questions. These came in from the regional Choose Our Transit meetings the last two weeks.
If you have a question for us, leave a comment here on the blog, send us a message on Twitter, or an email. We’ll feature more of your questions next week!
1) Where are stations on the rail line? , With Rapid Rail/DMU trains, what is the stopping distance? How close together can stations be? How many stations are in the rail alternatives and approximately where would they be?, Where would the RRT stops be on both the coverage and frequency models?
Exact station locations will be decided in future stages of project development. However, we will follow good practice by locating stations in areas of high activity such as downtowns and universities, and other locations consistent with local community plans.
Station spacing for Rapid Rail Transit depends on many factors but typically is 1-5 miles between stations. This is determined in part by development patterns, but also by stopping distance which varies and depends on the desired speed, the number of railcars, and on terrain. There is an unavoidable trade-off between the access of more stops and the travel time among stops. More stops = better access and slower travel time; Fewer stops = lower access and faster travel time.
Many station locations will be considered and the public will have an opportunity to provide input on the locations before a final decision is made.
3) How do you get to Durham on RRT?, How would Wake Co RRT interface with proposed rail in Orange and Durham counties?
The adopted Durham County Transit Plan includes a commuter rail connection to Raleigh along the same North Carolina Railroad corridor shown in the RRT scenarios. If the adopted Wake Transit Strategy includes the regional RRT project, the parties will work together to ensure that there is a “single-seat ride” between Wake and Durham stops on the line. Connections to Orange County would require a timed-transfer to an express bus at the RTP Station, or a transfer to the Light Rail line under development between downtown Durham and UNC Hospital.
4) What are the estimated travel times with rail and bus from downtown Raleigh to Cary/Airport/RTP?
There is a lot of further analysis that needs to be completed before we have confident estimates of these travel times. It will also depend upon the location in downtown Raleigh and in RTP since the stations for the RRT and BRT are likely to be in different locations. However, at this time, we can share that the rail travel speeds are assumed to be significantly faster than the bus travel speeds (an average of 45MPH for RRT vs. 20MPH for BRT). This would result in shorter travel times between the downtown Raleigh station and downtown Cary or the RTP train station. The bus travel time to RDU Airport would be shorter because it would not require a transfer.
5) For all scenarios, will riders be able to track the next bus/train to come to the stop?
We know that this is a tremendously useful resource for our customers and expect to extend it to all future bus or train services. Currently, customers can track the location of all buses in the Triangle on their computers (live.gotriangle.org) or mobile devices using the TransLoc app. It is also easy to get the next bus arrival information using text messaging. High boarding locations will also be evaluated for digital message signs with real-time arrival information such as already exist at Cary Train Station, the Regional Transit Center, Moore Square, and several other locations.
The Wake County Transit Strategy is being developed for a 10 year time-frame. Many people are asking why. Here’s an excerpt from the Expanded Choices report that explains.
The 10 year timeframe – used for the purposes of sketching the four alternatives — was chosen for two key reasons:
Very long-range plans can sometimes seem excessively remote, and difficult for the public to connect their current daily lives to. A decade was selected as a time frame which provides for the opportunity to exercise a degree of long-term vision, but which is likely to still feel immediate and recognizable for people in Wake County.
10 years is probably enough time, given a successful and aggressive approach to application for federal funding, to build a major infrastructure project such as those shown in each alternative.
It is important to note that the plan would be phased in over many years. Some improvements will occur within a few years and others will be closer to or during the tenth year.
Building on the ten year plan developed through this process the final Wake County investment strategy will also identify further investments that can be made after the first phase. Future studies and future decision-makers can modify these later investments as needed to react to how individuals and the market respond to the first phase of investment.
The expanded choices report goes into even greater detail on infrastructure needs, funding and other variable that will be considered within the ten year period. You can read all about the 10 year approach starting on Expanded Choices Report.
After you take a look at the report, be sure to tell us what you think. Your input will help shape the future of Wake County.
Last Friday we responded to a few of the most frequently asked questions from the regional Choose Our Transit events. This week we have a few more questions (and answers). If you have a question, please send it our way!
Will all the buses be the non-polluting hybrid?
We have not determined what types of buses will be used. The decision about what type of buses to purchase will be based on purchase cost, maintenance cost and the service being run as we move into the next phase of the project. It is worth noting that all new buses must meet stringent pollution requirements. Hybrid vehicles are currently more expensive the traditional diesel vehicles and current hybrid vehicles (because of the heavy weight of a transit vehicle) only provide significant pollution benefits on low speed, frequent stop routes.
Will bus stops be improved with roofs and better seats?, Can you ensure there is at minimum a bench at every bus stop before you go high tech?, For all scenarios, will stops have shelters? Very important to make riders comfortable.
Bus stops for the Bus Rapid Transit service will be platforms with shelters and have pre-board payment and fare collection equipment. Bus stop shelter, benches, trash receptacles, bike racks, etc. for local bus service improvements will be determined by each transit system, so they may vary throughout our community.
Typically, stops that have a higher per day usage are at a higher priority for determining if shelters or benches are required. With the expected increase in the number of passenger trips as more frequent and improved bus service becomes available, it is highly likely that a large number of stops will have improved passenger amenities.
Will wheelchairs be able to roll onto rail, BRT, bus? What about walkers?
All transit service will comply with the Americans With Disabilities Act (ADA) laws. It is expected that all BRT stations will have level boarding for ease with those passengers in wheelchairs, mobility devices, and walkers.
So this would replace all existing service in Cary? No service to SAS or Weston Parkway? Will CTran Center remain in the four scenarios?
In all of the scenarios, SAS, Weston Parkway, and Regency Park are all included in Cary’s bus service scenarios. The Depot or an area close to the Depot will remain the primary hub for C-Tran.
We’ve held seven events in the last two weeks to start discussion the four transit plan options with the community. These events have been well attended, and we are really excited to have gotten the opportunity to talk with several hundred people in just two weeks!
As we have been talking with people in the community, we have noticed several questions that have come up over and over. Today we are answering a few of them here as well.
If you have a question, please send it to us. We will be answering more questions on social media and through this blog in the coming weeks.
How would the transit plan options impact current bus services?
The number of days and hours of bus operations would be increased from current service with any future transit strategy. There may also be changes to existing routes. However, route changes would not happen without significant community involvement.
Where will stops and stations be located?
The four transit plan options are intentionally lacking exact route, stop and station details because they have not been developed. The more important concept for community discussion right now is the types of transit that will work for our community and the areas within our community that would be served by each option.
Not having exact routes, stops and stations helps facilitate the discussion around the needs of our entire community – and will help each of us to think beyond our individual circumstances.
How would the various transit plan options connect to the Airport?
Generally the four transit plan options will provide a much higher level of service to the airport. Today 30 to 60 minute service is available on weekdays and less frequent service is available on weekends.
Both Bus Rapid Transit (BRT) options would provide service every 30 minutes all day via I-40 and every 30 minutes all day to Morrisville (connecting to BRT). The Rail Rapid Transit (RRT) Ridership option would provide service every 15 minutes all day to Morrisville (connecting to RRT) and the RRT Coverage option would provide service every 30 minutes all day to Morrisville (connecting to RRT).
Rail and Bus Rapid Transit connections to the Raleigh-Durham Airport would require significant infrastructure improvements, making it very difficult geometrically (our Transit Consultant Jarrett Walker does a nice job of explaining geometic transit here). These challenges will be evaluated closely as a final transit plan and routes are developed.
Were other types of rail were considered?
Light rail was discussed. This mode of transportation requires electrification and the Federal Railroad Administration (FRA) regulations require light rail to be separated from freight tracks. This would require additional land and bridges, making this mode of transportation more expensive than other rail options.
Light rail would be difficult to implement incrementally because large expensive segments need to be implemented at one time in order to be considered for federal funding. Because of the high cost to build and operate a light rail system the cost per passenger can be high.
It is possible to deliver more service to more people using a simpler and less expensive technology (Rapid Rail Transit) that can share space on the existing rail corridor. This concept would use Diesel Multiple Units (frequently called DMUs) and is being explored further.
Utilizing DMUs would require additional tracks within the existing rail right of ways so we can run high frequency service using diesel powered vehicles while still leaving room for freight, passenger service, and future rail traffic needs.
Another benefit of this technology is that while light rail’s high infrastructure cost means that it can only be used for very frequent service, the proposed DMUs can be used at any frequency, a hybrid blend between light rail and commuter rail.
How do the transit plan options serve lower income communities?
It is very important that low income communities have access to public transportation. We also know that lower income positively correlates to transit ridership, which is a goal for our transit strategy. This has made income and equality issues paramount throughout the planning process.
We welcome your thoughts and feedback on how each of the transit plan options would serve our key customers and improve service to communities that rely on transit.
The first of the Choose Our Transit events is just a few hours away. It will be the first public opportunity to review the four Transit Plan Options that have been developed for Wake County and, more importantly, the beginning of a new round of public feedback.
The four plans that will be unveiled this evening contrast each other and will help our community continue to discuss the choices and trade offs that we must make for the future. The goal is not to choose one of the alternatives, but to take the best of two or more options and combine them into a plan that will meet the needs of our entire community well into the future.
The feedback from this phase will lead us to a final plan later this fall.
