ABSTRACT
Minimum parking requirements create too much parking, reduce the supply of housing, and increase traffic congestion. In 2004, London reversed its parking requirements, eliminating the minimums and putting new maximums on parking supply for all developments in the metropolitan area. The London parking reform was part of a national agenda to transform transportation policy in the United Kingdom that began years. Because density and transit accessibility are integral to parking policy, authors examined how the parking requirements and actual supply vary in relation to these factors using the post-reform dataset. The number of parking spaces supplied after the 2004 parking reform fell by approximately 40 percent when compared to the number of parking spaces that would have been supplied with the previous minimum parking requirements. This means that from 2004 to 2010, the new parking requirements led to a total of 143,893 fewer spaces.
