Manville Points to a ‘Shortage of Road’

The Financial Times quoted Associate Professor of Urban Planning Michael Manville on the growing issue of urban congestion. According to Manville, congestion is caused by “a shortage of road: There is more demand for road space than there is space available.” Manville drew a parallel between roads and other utilities like water and gas, explaining that “the big difference between road networks and other utilities is that we don’t meter for use. Consequently, roads are the only type of infrastructure that suffer from regular shortages.” Manville recommends congestion pricing to encourage drivers to make fewer trips or take public transport. He argued that “Americans just drive more than they need to” because of the lack of associated costs of driving. Congestion pricing has been successful in London, Stockholm and Singapore, and New York is planning to implement the policy in 2021.
