The Weakest Link: A Model of the Decline of Surface Transportation Networks

Xie, Feng; Levinson, David - Networks, Economics and Urban Systems Research Group … - 2007

This study explores the economic mechanisms behind the decline of a surface transportation network, based on the assumption that the decline phase is a spontaneous process driven by decentralized decisions of individual travelers and privatized links. A simulation model is developed with a...
