Michael Manville, associate professor of urban planning, was featured in a Sierra Club article about the prospect of congestion pricing in major U.S. cities. Earlier this year, paralyzing traffic delays in New York City prompted the state to approve a plan to implement congestion pricing by 2021, and Los Angeles recently approved a two-year study to investigate the feasibility of the traffic-management strategy. By charging people to drive on traffic-clogged roads, congestion pricing encourages people to drive at different times, carpool or take public transit, all while reducing carbon emissions and raising revenue for transportation projects. Manville explained that congestion pricing is “the only thing that has ever been demonstrated to reduce [congestion]. So either we can do this or everyone has to stop complaining.” Manville reiterated his support for congestion pricing as one of the most viable solutions to traffic gridlock in a Shift article.
