OPTIMIZATION OF LARGE TRAFFIC SYSTEMS.

A program for optimizing most of the significant traffic engineering quantities while allowing for the fact that drivers can and do change their routes and modes of travel is proposed. The program requires the person origin-destination table as input and gives the best traffic-signal settings, reserved-lane assignments, and ramp-metering rates as outputs. the optimization can be for minimum person time, for minimum fuel consumption, or for a combination of both. The optimization was coded by using arbitrary but reasonable models for the components and run for a hypothetical network. Sample results are given.
