The Los Angeles Time seems surprised to report that Los Angeles’ 9-mile-long Expo Line has failed to relieve congestion in the corridor it serves. Rail and bus boardings increased about 6 percent after the line opened in 2012 (at least some of which would be due to transfers of passengers from bus to rail who previously could go the entire distance of their journey by bus), but the rail line had no “significant or consistent impact” on auto traffic.
Many people believe rail transit depends on population density, and if so then the Expo Line should be a perfect candidate, as the area it serves has 26,000 people per square mile (about the same as New York City and nearly ten times the average urban density in the United States). On one hand, even that’s not dense enough for rail to attract a lot of riders. On the other hand, light rail is really low-capacity transit, so is truly the wrong solution for areas of high transit demand.
As the L.A. Times observes in other articles, rail does benefit some people. First, it gives perverts opportunities to engage in anonymous sexual harassment. Second, it gives politicians opportunities to spend a lot of money: with the prompting of Governor Jerry Brown, Los Angeles is considering spending billions of dollars on six more rail lines.
One thing building rail doesn’t do is get many people out of their cars. In 1980, before building any rail, Los Angeles transit carried 5.9 percent of commuters to work. Today, after building six light-rail, one heavy-rail, and seven commuter-rail lines, transit’s share of commuting is all the way up to 6.0 percent–and only 13.5 percent of those transit commuters take the train.
