Alexandria, Virginia: A New Network Plan

At about 15 square miles, the City of Alexandria is relatively small, but it is firmly within the core of the Washington metropolitan region with key job centers like the large Department of Defense facility at Mark Center, a historic Old Town that draws many tourists, burgeoning employment centers like Eisenhower East, and many leafy suburban neighborhoods. It grew and changed dramatically, along with the rest of Washington region, in the latter half of the 20th Century, much of it in an auto-oriented design. And like many of the inner suburban areas of the Washington region, Alexandria is trying to find its way to a more transit-focused future, because in the nations 6th largest metro area, there’s just not room for everyone to get around by car.

When looking at Alexandria in the context of the ridership recipe, a key feature is that most of the density is around the edges of the city, along the Metrorail lines to the east and south, and along I-395 to the north. But not all of that density is equally suited to high transit ridership. In the western parts of the city, much of the development is auto-oriented, with less connected streets and poor walkability. In the middle of the city is a large area of primarily low density residential that is not dense or walkable. This doughnut pattern makes the transit network design and planning work particularly interesting and challenging for Alexandria.

In that context, we’ve been working with the City, its local transit agency (DASH), and the regional transit agency (WMATA), on the Alexandria Transit Vision since 2018. The City recently released the Draft Recommended Networks that we helped design.

The networks are designed around the policy direction from the DASH Board that, by 2030, 85% of resources should go toward high ridership service. The plan includes a short-term network that could be implemented as soon as 2022, with no new service hours. It also includes an option to improve evening and weekend service in the short-term with new investment. Plus, the plan includes the ambitious Vision Network, a 2030 plan to expand the frequent network and evening and weekend service to substantially increase access across the city, seven days a week.

A major focus of the plan is building up a frequent network from what is mostly a low frequency system with lots of one-seat rides today. That means some trips that a person can make today on one bus might require two buses in the future, but the frequency of service means that total wait time is the same, or less, than today.

The slices of the network maps below show the western part of the city, where today many overlapping routes provide low frequency service to many destinations, but you can’t get anywhere soon with such long waits. The 2022 and 2030 networks dramatically simplify service and increase frequency to expand liberty and access through connections to other frequent routes.

Outcomes

The 2022 Recommended Network would increase the number of jobs that the average person could reach in 45 minutes at midday on weekdays by 13%. That is with a network with zero increase in service hours, just reallocating existing DASH and WMATA services in the city.

An 8% increase in service in the short-term (2022) could improve evening and weekend service so more people could get more places all week long. Specifically, it would increase the percent of residents near frequent service on Saturdays from 36% to 65% and on Sundays from 15% to 59%.

The longer-term Vision Network for 2030 would increase job access even more, helping the average resident reach 18% more jobs in 45 minutes at noon on weekdays. Plus, it would increase evening and weekend service, brining frequent service to 79% of residents on Saturdays and 74% on Sundays.

The vast majority of people and places in Alexandria see substantial improvements in overall access and freedom via transit with these networks, but like any change there are some trade-offs. Some parts of the city, particularly in the lower density center, see a decrease in service and also a decrease in access by transit.

These trade-offs were part of the concepts phase where we helped the public, stakeholders, and city leadership think through what goals they wanted to prioritize for transit in Alexandria. The outcome of that phase was the Board policy direction telling us to put 85% of resources toward Ridership Goals and 15% toward Coverage goals.

Your Liberty

We’ve also put together an interactive webmap that you can use to explore the networks and see how they affect your liberty and access to opportunities: http://alexandriatransitvision.com/. The tool compares travel time isochrones for each concept and shows you the change in jobs reachable in 30 or 45 minutes.

In these maps, blue areas are newly reachable with the network concept, purple areas are reachable with both the existing network and the concept, and red areas are where you can travel with the existing network that is no longer reachable with the concept. You can also click the “View Routes” button to explore the network structure.

Here’s a quick comparison for the Landmark Mall vicinity showing the area that would be reachable in 45 minutes with the 2030 Recommended Network:

The City is working with developers to remake this area of the City, adding new housing and commercial development. With the 2030 network, someone living here would be able to reach 76,800 more jobs than with the existing network. Of course, those jobs aren’t just places you could work, they also represent the shopping, education, recreation, and other opportunities you could reach in a reasonable amount of time.

More Information

There’s much more detail in the Draft Recommended Network Report and at the city’s website, including individual neighborhood details.

If you live, work, or visit Alexandria, you should consider these changes and take the survey about them here. At this stage there is no decision about whether to implement a plan such as this one.  Any final plan will be revised based on public comment that comes in over the next couple of weeks.  That means that if you like the plan, it’s important to comment to that effect, as well.

Miami: Starting a Network Redesign

We’re excited to get started on a bus network redesign in Miami!

Miami-Dade Transit runs a large network of about 100 routes, running over 750 buses across a huge area over 40 miles long. Over the last five years, the Metrobus system has lost about 1/4 of its riders, which has caused Miami-Dade leadership to question the current bus network and how well it’s serving the county.

Like many other Sunbelt cities, Miami is growing and a lot of that growth is in a few places: around downtown, on the beaches, and in a few key centers such as Coral Gables. These densifying centers are reaching the point where cars simply don’t work anymore, and transit is essential to the continued growth and prosperity, not to mention equity. Thus, there are increasing demands for more useful service in these core areas.

As in many cities, the edges of the region are also seeing new development designed almost entirely for car dependence. And many people moving to the edges are doing so because they have limited incomes and the housing is cheap. But the land use design and distance means that the cost to serve them with transit is very high. These trends are stretching Miami-Dade Transit farther and farther geographically on a limited budget. This combination of forces is putting great demands on transit in opposite directions and is heightening the difficulty of the ridership-coverage tradeoff.

A key question in the process will be the different roles of different transit agencies. Many municipalities have begun running their own municipal bus routes. Some, like the Miami Beach network, are extensive. As Miami-Dade has lost riders municipal systems have seen big ridership increases, rising from 7.4 million riders per year in 2013 to 10.9 million in 2017. Where these municipal routes compete with county-wide Miami-Dade routes, many people are choosing the municipal routes, in part because they are free. These trends are causing greater segmentation of transit services across the county and adding to the complexity that an average rider must manage when trying to figure out how to make a trip or trying to understand the whole system.  They also represent a degree of duplication that could potentially be reallocated to create more frequent and useful service.

As always, public input (including but not limited to riders) will be essential to figuring out what direction Miami-Dade wants to go. For that effort, we are especially excited to partner with Transit Alliance Miami, a local non-profit organization advocating for walkable streets, bikeable neighborhoods and better public transit. Transit Alliance advocated this project for years, and now they are actually leading the process on behalf of Miami-Dade County, with a big emphasis on involving the community in decision-making throughout the process. We think this is the first US bus network redesign that is led by a community advocacy group.

We expect there will be some early outreach on key choices in the summer. In the fall, we expect to release two concepts for how the future network could look, and this will be a key point for public input. All of that input will guide us on a final plan, which we expect will be voted on this winter. Keep an eye on the Transit Alliance twitter feed and website for regular updates throughout the redesign process and opportunities to provide input and respond to concepts.

Cleveland: Tell us what you think about these alternative networks!

Our work on Greater Cleveland’s transit network is now available online, and we’re looking for people from the area to provide their input through this online survey.  The transit agency, GCRTA, hired us this year to help develop transit network alternatives that would illustrate what the transit network could look like if it shifted its focus more towards attracting higher ridership, and what it what the network would look like if it shifted towards extending coverage, as well as what the possibilities may be with different levels of funding.

The local newspaper, the Plain Dealer, has a great article about the networks and what they are intended to illustrate.

Cleveland is fortunate to have a relatively dense, and walkable pre-war era development pattern across much of the city, but as with most places in the United States, the trend over the past half-century has been the continual spread of residents and jobs to far-flung locations across the region. Since the region as a whole is growing very slowly, or not at all, this slow dispersal of the tax base poses a long-term challenge for the stability of transit resources and travel markets as more people and jobs flee to the margins of Cuyahoga County, or beyond.

When operating resources are limited, as in GCRTA’s case, the ridership/coverage tradeoff is put front and center in any discussion of what transit can do. Today’s network extends to most, but not all, of the developed area of the county, and provides little high-frequency service within the dense, walkable core of the region. Reaching more of Cuyahoga County would mean curtailing frequency in dense areas even more. But building a robust frequent network would require pulling back from many of these lower-density suburban areas, as there is little waste or duplication to reallocate in the current service design of RTA’s network.

In this context, RTA has brought us in to help explore what the transit network could look like today, if different policy priorities were emphasized more strongly in network design. Further on in the project, we’ll also be developing alternatives for different financial scenarios. Right now, RTA is conducting outreach on two alternatives: a High Frequency Alternative which brings frequent service to most of the dense, walkable central areas of Cleveland and the inner-ring suburbs, and a Coverage Alternative, which spreads low-frequency service to more of county.

The purpose of these alternatives is to illustrate for the public, stakeholders, and the agency’s Board of Trustees the potential outcomes of a policy choice to focus more on ridership or on coverage. (You can click each map below to explore a larger annotated version).

The High Frequency Alternative concentrates service so that lines run more frequently, reducing waiting times and making travel by transit more convenient. The network would reach fewer places, but where it does reach, trips would be faster than with the Existing Network.

As a result, over 40% more jobs would be accessible by the average county resident in an hour with the High Frequency Alternative. But on the other hand, the reduction in overall network extent reduces the number of people within a ½-mile walk to transit by over 20% from current levels.

You can compare the structure of the network on Cleveland’s east side to see this principle in action:

GCRTA Existing Network (left) compared with the High Frequency Alternative (right)

On the other hand, the Coverage Alternative spreads out service across the county, but spreading it out means spreading it thin. Frequencies would be lower throughout the network. This means that the network reaches more places but some trips would take much longer. Because these are budget-neutral alternatives, expanding the reach of the network requires reducing service levels on other routes, some routes that run every 45 minutes today would run every 60 minutes, and RTA’s single existing 15-minute bus service would run every 20 minutes. About 25,000 more people would be within a ½-mile walk of a transit stop, about a 5% increase from the Existing Network.

We hope these alternatives clearly illustrate the ridership/coverage tradeoff as it applies to Cuyahoga County and Cleveland. If you live in the area, please tell us what you think! You can learn more about the project and alternatives here.  Then, if you live, work or study in Cuyahoga County, be sure  take this short online survey.

 

 

 

 

 

 

 

 

Richmond, Virginia: our Redesigned Network starts June 24!

On Sunday June 24, 2018 Richmond, Virginia will wake up to a new transit system, including its first Bus Rapid Transit line — the Pulse.   The redesigned network for the whole city is the result of a design process that our firm guided, in cooperation with the local office of Michael Baker International, for the City of Richmond and Greater Richmond Transit Company (the transit agency).

The redesign process began in early 2016 with our team leading city staff, stakeholders and the public in a conversation sparked by our Choices Report. We focused on key trade-offs, like ridership versus coverage and the right balance between peak service and all-day service.  Importantly, this project was led by the City of Richmond, not the transit agency, so it was closely aligned with the city’s own goals for itself, including its redevelopment.

We then developed three concepts of how to redesign the City’s bus network around the new BRT line and guided a conversation around those concepts and the goals they represented. The Familiar concept represented little change.  A Coverage concept focused on covering every part of the city even where ridership would be low.  A Ridership concept focused more on high-ridership services, like frequent lines in high-demand corridors.  Response from the public and stakeholders leaned toward the Ridership concept, though there was a wide diversity of opinion.

The top map shows the original proposal for the east end of the city.   Red = every 15 minutes.  Blue = every 30 minutes. Residents told us they preferred shorter walking distances and lower frequency, so we revised the proposal to the map below.

By January 2017 we published a draft recommended network with six new high frequency lines in addition to the BRT, clockface frequencies, more through-routing (instead of terminating) downtown, and a network that maintained nearly all existing coverage of people and jobs.

While response to the draft recommendation was very positive, the East End of the city raised some concerns. We had designed a high frequency line (Route 5 in the map) that required a longer walk for some residents. After more thought and review, the community and the city decided they would prefer to have shorter walks and longer waits. So, we revised the network design to have two lower frequency lines (Routes 5 and 41 in the map) instead of one higher frequency line.

We published the final network plan in March 2017 and since then the City and GRTC have been working hard to prepare for the big day when everything changes overnight, including additional tweaks and updates to the network in light of new information and additional community feedback. But overall, the basic network structure that will be implemented on June 24 is what was in the final plan from March 2017.

You can see how the new network drastically simplifies things by comparing the existing system

The top map shows the network before the redesign and the lower map shows the network after the redesign.

map to the new map in near west part of the city, which includes the Fan and Museum District neighborhoods. Previously, many routes piled together onto Broad Street to create a lot of service there, but it was not well organized and led to more bunching of buses than useful frequency. The new network is radically simpler, with more direct lines and frequent lines focused on the major east-west corridors in this part of the city. So there are now two major frequent lines in this area, the BRT line on Broad Street and the frequent Route 5 on the Main/Cary couplet.

And there is a new orbital line (Route 20) connecting the north, south and west parts of the city without requiring a transfer downtown. This is really important for Richmond because of the prevalence of jobs in the western part of the region while most lower cost housing is in the north, south, or east.  We wanted this line to be every 15 minutes, and we hope it will be soon; for now, budget constraints are holding it to a 30 minute frequency.

Also, GRTC has taken this opportunity to improve the communication in its system map. In the old map colors represented which parts of the city each route served. In the new map, colors represent frequency, which makes it much easier to see where the useful service is. (The new map is by our friends at CHK America, but the red-blue-green color scheme for frequency is one we’ve been using for years.)

Throughout the process we led the network design and guided the stakeholder conversations. We worked closely with our local partners at Michael Baker International who led the public outreach and key local government coordination. And the City provided strong leadership throughout to ensure the process led to a clear and convincing direction when City Council unanimously approved the policy direction for the plan in February 2017.

We’ve had fun working with GRTC, the City and surrounding counties on a ten-year plan for transit improvement. We’ve been leading an intensive effort on the network design in Henrico County, which covers Richmond’s northern suburbs, including concepts for a major expansion of transit into the county.  That is all leading toward a new Transit Development Plan for GRTC which will be completed in the next few months. Meanwhile, Henrico County has already taken major steps to implement parts of the plan. Starting in September, there will be evening and weekend service on three routes in Henrico (currently they do not have any service in the evening or on weekends). They will also extend service to the airport and along West Broad Street to Short Pump to serve the one of largest suburban office parks in the region and the largest shopping mall in the region.

When local governments start leading on transit, big things can happen. The fast movement on so many fronts in the last two years is due, in part, to the City of Richmond and Henrico County taking a much stronger role in guiding and planning for transit in coordination with GRTC, instead of leaving all the advocacy to the transit agency.

We’re pleased to have helped shepherd the conversation to this point, but much credit goes to all the GRTC, City, County, State, and regional agency staff (and other supporting consultants) who have worked hard on these issues for years and to the local transit advocates and organizers who have built grass roots support for more transit across the region.

So, get excited, Richmond and Henrico, for your new transit system is coming soon. And for those of you from other places who are interested in experiencing a transit redesign first hand, perhaps you should plan a long weekend trip to Richmond for the June 24 opening. You could even volunteer to help with the changeover!

New York: Bus Network Redesign on the Horizon!

by Christopher Yuen

MTA New York City Transit has just unveiled a plan today to completely revamp its bus network.   Some elements of the plan that will be especially impactful (from their press release) include:

A completely redesigned bus route network.  NYC Transit is performing a top-to-bottom, holistic review and redesign of the entire city’s bus route network – the first in decades – based on public input, demographic changes and travel demand analysis.  Route changes will provide better connectivity and more direct service in every neighborhood, with updated stop spacing and the expansion of off-peak service on strategic routes.

Collaboration with NYCDOT, NYPD, & local communities.  NYC Transit will collaborate with NYCDOT [the city’s Department of Transportation] to expand the implementation of bus lanes, exclusive busways, queue jumps, bus stop arrival time displays and bus priority technology on traffic signals and buses known as “traffic signal priority.”  Many of these changes will also require robust community outreach.  NYC Transit will also advocate for strengthened [police] enforcement of bus lanes, dedicated transit-priority traffic teams, and legislative approval to expand bus-mounted cameras beyond 16 existing routes to help enforce bus lane rules in more locations.  (Most of the big wins in urban transit require transit agencies and city governments to work together.)

Speeding up boarding by using all doors.  NYC Transit is pursuing new approaches to speed up bus boarding, particularly using upcoming electronic tap-to-pay readers to facilitate all-door boarding.  While purchasing fare media with cash will always be an option with the new fare payment system being developed by the MTA, NYC Transit will also explore cashless options to speed up boarding time in select circumstances.

Transit routes are often tweaked in response to infrastructure changes, local desires, and complaints. Some of these changes serve specialized markets and may work well for some people’s specific trips, but over time, they erode the ability for a system to work well for the everyone else.  It takes a clean-slate redesign approach to create a network of simple, frequent and reliable lines.  The result, as has been the case in Houston, Coloubus, and Anchorage, is usually less routes in total, but more routes at higher frequencies all day, 7 days a week.

It’s also promising to see the New York MTA include measures to improve the speed and reliability of buses.  Since the speed of urban transit is not determined by how fast vehicles go, but by how often they have to stop, increased stop spacing, all-door boarding and properly enforced bus-only lanes will help keep people moving, especially during rush hour when traffic congestion and crowding has its worst impacts.   It’s also important to note that for transit, time is money, so faster service means more service for the same operating budget.

New York’s plan is ambitious, and potentially very impactful, so this will be an interesting story to follow over the coming years.
