Michael Manville, associate professor of urban planning, spoke to Curbed LA about measures being taken to combat traffic congestion in Los Angeles. According to a newly released index on congestion and mobility, the typical Los Angeles driver logged 103 hours of traffic in 2019. The index also found that the metro area is home to the two most congested stretches of road in the country, on sections of the 5 and 134 freeways. Among other strategies to lighten traffic, transit agencies plan to expand rail lines. While this would provide an alternative to driving, it may not reduce traffic, Manville cautioned. “It basically allows people to avoid exposure to congestion. But if you want to actually improve congestion on the 405, the unfortunate truth is that you have to toll the 405,” he said.
