SIMULTANEOUS OPTIMIZATION OF OFFSETS, SPLITS, AND CYCLE TIME.

This paper describes a new computer method, mixed-integer traffic optimization, designed to optimize simultaneously all the traffic control variables of the network. The method has been programmed in conjunction with the mixed-integer routine of IBM's MPSX optimization system and thus provides a globally optimal procedure. It was applied to several traffic signal networks and is shown to offer certain advantages over existing methods. An example is presented to illustrate the input requirements, output format, and application of the program.
