According to the Access Across America: Auto 2018 study, the Minneapolis-St. Paul metro area ranked sixth in terms of job accessibility but 28th in the reduction in job access due to congestion. In fact, Minneapolis-St. Paul this year edged above the much-larger Houston, which ranks seventh and has a million more jobs.
"Every year I look at these results, it’s stunning how well Minneapolis-St. Paul does in making it easier to get to work compared to other major U.S. metros," says Andrew Owen , director of the Observatory. "We have a well-designed and well-managed transportation network that connects people to lots and lots of jobs."
By contrast, Philadelphia ranks sixth nationally in total jobs but ranks 13th in access to those jobs and in congestion delays. The Boston metro, which ranks 10th in total jobs, also faces significant challenges, ranking fifth in congestion delays and 17th in accessibility.
The rankings focus on accessibility, a measure that examines both land use and transportation systems. Accessibility measures how many destinations, such as jobs, can be reached in a given time.
Key factors affecting the rankings for any metro area include:
- the number of jobs available and where they are located;
- the road network structure, traffic management practices;
- the provision of alternate transportation modes;
- and, population size, density, and location.
Better coordination of transportation systems with the location of jobs and housing will improve job accessibility by auto.
The findings have a range of uses and implications. State departments of transportation, metropolitan planning organizations, and local government agencies can apply the evaluations to performance goals related to congestion, reliability, and sustainability. In addition, detailed accessibility evaluation can help in selecting between project alternatives and prioritizing investments.
The annual study, part of the Access Across America study that began in 2013, ranks the 50 largest (by population) metropolitan areas in the United States for connecting workers with jobs by auto and measures the delay getting to those jobs due to traffic congestion. Cars, trucks and other private motor vehicles are used for an estimated 86 percent of commuting trips in the United States, making it the most widely used commute mode.
Rankings of the top 10 metro areas for job accessibility by auto in 2018 changed only slightly from the previous year, with Los Angeles, New York, and Dallas topping the list. Rankings for the top 10 metro areas for loss in job accessibility due to congestion are topped by Los Angeles, Riverside, and New York. The Washington, D.C., metro area fell to eighth, likely due to the unavailability of census data on federal workers.
This year’s report also includes detailed block-level maps that illustrate the spatial patterns of accessibility within each area.
