Wachs Defends Controversial Plan to Combat San Diego Traffic

Martin Wachs, distinguished professor emeritus of urban planning, spoke to the San Diego Union-Tribune about the county’s newest plan for improving traffic. The San Diego Association of Governments (SANDAG) proposed a controversial plan to invest in a high-speed commuter rail and implement congestion pricing on existing freeways. The proposal shelves planned freeway expansions, which experts have found does little to solve traffic congestion. According to Wachs, “the only proven way to reduce traffic is congestion pricing.” While the policy has been politically unpopular in the U.S., it has “increased highway capacity in the 30 or 40 places it’s been done around the world.” While the rail would not necessarily reduce traffic congestion, it would accommodate population growth in the region while reducing greenhouse gases from cars and trucks. “Transit enables higher density development and reduces vehicle miles traveled in relation to the population, whereas highways are associated with more dispersed growth,” Wachs explained.


Wachs Discusses Freeway Tolls and Traffic Congestion

UCLA Luskin’s Martin Wachs, distinguished professor emeritus of urban planning, commented in a Los Angeles Times article about freeway tolls and other revenue-generating methods that could get drivers off the road and help reduce traffic congestion. The issue has prompted L.A. Metro officials to push for a study of congestion pricing in Los Angeles, which includes controversial steps such as converting some carpool lanes to toll lanes and charging drivers by the number of miles they travel. The anticipated billions of dollars in revenue could help expand the region’s transit network. “This would take a very dynamic leader and a very committed leader, and most American politicians back away when they see the opposition,” said Wachs, who said he supports the idea as a good first step. The story also mentions a new study by UCLA Luskin’s Michael Manville that analyzes the reasons that people support transit projects.
