The state of public transit in the 100 largest American cities

Posted on by

The Brookings Institution just released a new report, Missed Opportunity: Transit and Jobs in Metropolitan America, examining the mass transit systems in the 100 largest American cities. Here are some of the findings:

Nearly 70 percent of large metropolitan residents live in neighborhoods with access to transit service of some kind…

The typical metropolitan resident can reach about 30 percent of jobs in their metropolitan area via transit in 90 minutes…

About one-quarter of jobs in low- and middle-skill industries are accessible via transit within 90 minutes for the typical metropolitan commuter, compared to one-third of jobs in high-skill industries…

Fifteen of the 20 metro areas that rank highest on a combined score of transit coverage and job access are in the West…

With the primary focus of the report on jobs, there is a lot of interesting data. Here are a few things I noticed in going through the full report:

-Page 3 highlights three trends for metropolitan areas: “metro growth and expansion” with both city and suburban growth during the 2000s, “employment decentralization” (with a figure that only roughly 20% of metropolitan jobs are within 3 miles of the city center), and the “suburbanization of poverty.”

-Page 4 notes some of the problems of mass transit in today’s metropolitan regions: “old hub and spokes” which don’t work as well since “39 percent of work trips are entirely suburban” (a problem in the Chicago region, hence the need for the Star Line), “serving low-density areas” (a problem in many suburban areas and a recurring problem in the western suburbs of Chicago such as Naperville), and “spatial mismatch and the costs of transportation” (the idea that the people who work in certain jobs/industries don’t necessarily live near these jobs).

-Page 13 has an explanation for why they chose a 90-minute one-way commuting threshold in the study. If you change the threshold, the percent of jobs available changes quite a bit: “[A]cross all metro areas, the typical worker can reach about 30 percent of total metropolitan jobs in 90 minutes. At a 60-minute commute threshold, only 13 percent of jobs are accessible for the typical worker. For a 45-minute commute, the share drops to 7 percent.” This seems to be quite a high threshold but as they note, more than half of metropolitan commutes are longer than 45 minutes (according to 2008 American Community Survey data).

-Page 18 has a graph comparing the availability of high/medium/low skill jobs within 90 minutes by city or suburban setting. Interestingly, a higher percentage of jobs accessible from the city were high-skill while a higher percentage of accessible suburban jobs were low-skill.

-Pages 20-21 look at some of the differences between the West, with the most accessible mass transit and higher percentage of accessible jobs, and the South, the region at the other end of the spectrum. The findings about the South are not too surprising as it is known for sprawl but the finding that the West dominates the list of cities (15 of the top 20) is interesting. Does this suggest that these Western cities have made much more concerted efforts to provide mass transit?

If you look at the more specific data for the Chicago region, it appears to be fairly average compared to the other 100 metro areas.

The importance of the railroad to Will County’s projected growth

Posted on by

When Will County officials look at a map of Metra commuter rail lines in the Chicago region, they see limited services for a growing region. Indeed, communities like Joliet and Plainfield are quickly growing. Will County officials came together Monday to praise a new study that will look into improving train options for this area:

Several communities have pegged developments to improved service on the Heritage Corridor. But those suburbs have been frustrated in recent years by the slow pace of adding Metra trains.

Local officials said Monday they were pinning their hopes on the Heritage Corridor to help residents get downtown now and in the future.

“I truly believe the need is there more than ever, and the consensus is we are going to see Will County in the next 20 years jump to (more than) 1 million people to become the second-most populated behind Cook,” said Will County Executive Larry Walsh.

The study will help establish the line as part of the proposed high-speed rail corridor between Chicago and St. Louis, Hannig said.

Several pieces of information are interesting:

1. Many might think that the railroad ceased to be important for suburbs around the time that interstates were built (late 1950s in the Chicago area). But these railroad lines still play an important role: they are a commuting option but also give suburbs a flow of people in and out of the downtown as well as a center for which development can be anchored. Along other Metra lines, numerous communities have built condos and mixed-use developments.

2. Will County will have more than 1 million residents in 20 years? This would require growth rates like the county has experienced since the 1950s: in every decade except the 1980s, the county has experienced at least 30% growth. I wonder what DuPage County, the current 2nd most populous county in the region, thinks of this projection.

3. There is some Metra service to Chicago but the options are limited. The article suggests that this limited service leads to limited use: this line is “Metra’s least-used line, with an average weekday ridership of 2,600 passengers.” (A little comparison with these numbers: I believe both Naperville train stations easily exceed this each weekday.) So if the rail service is improved, will this necessarily lead to more riders as the political leaders suggest? Why can’t the officials look at some commuting data to figure out how many Will County residents work in Chicago versus in other suburbs?
