摘要Cities are shaped by transportation infrastructure. Older cities were anchored by waterways. Nineteenth century cities followed the path of streetcars and subways. The 20th century city rebuilt itself around the car. The close connection between transportation and urban form is natural, since cities are defined by their density. Physical proximity and transportation investments serve the common cause of reducing the transportation costs for goods, people and ideas. The close connection between transportation and urban form suggests the need for spatial equilibrium models that embed a full set of equilibrium effects into any evaluation of transportation spending. Their connection implies that restrictions on land use will change, and often reduce, the value of investing in transportation infrastructure. Future transportation innovations, including autonomous vehicles and telecommuting, are likely to also change urban form, although cities often take decades to adapt to new forms of mobility.
