Network Equilibrium and Pricing

摘要: Traffic equilibrium models are commonly in use for the prediction of traffic patterns on transportation networks that subject to congestion phenomena. Even though their application various planning contexts has increased dramatically over past twenty five years, due development efficient solution algorithms and increasing power computing platforms, they based concepts have been stated more than seventy years ago. The idea originated as early 1924, when Knight gave a simple an intuitive description postulate behavior under congested conditions, follows: Suppose between two points there highways, one which is broad enough accommodate without crowding all may care it, but poorly graded surfaced, while other much better road, narrow quite limited capacity. If large number trucks operate termini free choose either routes, will tend distribute themselves roads such proportions cost per unit transportation, or effective returns investment, be same every truck both routes. As narrower develops, until certain point it becomes equally profitable broader poorer highway.
