Abstract

A control technique for digital computer control of a safety warning system for urban freeways was developed and evaluated. Traffic energy was used as the control variable. Computer logic was developed centred about critical energy as the control parameter. The ability of the critical energy parameter to detect stoppage waves was studied and evaluations were made of the performance, reliability, stability, and sensitivity of the control logic.
