How Good Is the Transit Where You Live? Measure It With AllTransit

The top ten rankings are great conversation fodder, but the real strength of AllTransit is its deep reservoir of data, enabling multifaceted analysis of transit quality at many different scales. Table via AllTransit.

Do you have the sense that transit in your city could be a lot better, and you want to show your local elected officials what needs to improve? Look no further: Chicago’s Center for Neighborhood Technology has produced a new tool called AllTransit that assesses the quality of transit down to the neighborhood level.

AllTransit lets you evaluate your local transit system in several ways. You can look up how many people in your city live within a half mile of transit service, for instance, or how many jobs are conveniently accessible via transit from your neighborhood compared to your city as a whole.

The tool combines route and schedule information from 805 American transit agencies with a wealth of Census data, making a broad spectrum of uses possible. With AllTransit, you can compare different facets of transit service across neighborhoods, cities, regions, states, or electoral districts.

To help people summarize complex comparisons, AllTransit offers an overall “performance score” incorporating several factors, including the extent of frequent service and how well transit connects people’s homes to jobs and other destinations.

The emphasis on frequency is unprecedented, said Linda Young, director of research for CNT. “Frequency is so important because it’s really the determinant of how people are going to use transit,” she said.

Here are a few ways you can use the tool, with Madison, Wisconsin serving as an example. Keep in mind that this is by no means a comprehensive list. Below are the city’s performance score and top-level stats — click to enlarge.

You can drill down and look at transit accessibility from a number of perspectives. Employers looking to see how many people could get to a potential workplace via transit in a reasonable amount of time, for instance, can call up this view:

You can also layer in demographic data to see how well different populations are served by transit. This map shows the share of black residents in Madison who live within half a mile of transit:

AllTransit’s ranking feature lets you look up the top performance scores within a given area. Madison rates sixth among Wisconsin cities and towns with more than 5,000 residents:

This only scratches the surface of what you can do with AllTransit.

CNT and TransitCenter, which funded the project, see AllTransit as a powerful tool to help local transit and housing advocates, public officials, business leaders, and other interested parties understand the strengths and weaknesses of transit in their communities and make compelling arguments to improve it.

Introducing a New Streetsblog Series: Getting Transit Right

|
With more American cities raising impressive sums to expand transit, the question of how to invest effectively is increasingly essential. So far, few places have hit on a policy combination that makes transit more useful to more people. To help cities "get transit right," Streetsblog is launching a new series about which transit strategies are working and which are not.

Why Is Transit Ridership Falling?

|
Transit ridership took a turn for the worse in 2016. In all but a handful of cities, fewer people rode trains and buses, and it's not just a one-year blip, either. In many American cities, the drop in transit ridership is an established trend. The big question is why.

Many Americans Live Near Transit, But Few Live Close to Good Transit

This chart tells an eye-opening story about access to transit in the United States. Using the new data tool AllTransit, TransitCenter dug into who has access to transit in American cities, making a crucial distinction between residents near any transit whatsoever and residents with access to convenient, frequently running service. The analysis encompassed the nation’s 25 largest cities and […]

How Much Driving Is Avoided When Someone Rides a Bike?

|
If Jane Doe rides her bike a mile to the post office and then back home, is it fair to assume she just avoided two miles of driving? And can we then assume that she prevented 2.2 pounds of carbon dioxide from being emitted? That’s more or less the way most agencies calculate averted vehicle-miles traveled. One […]
