Advanced coordination between a traffic control center and its supporting units

Abstract

This paper describes a new Central Traffic Control System (CTCS), implemented in several sites in Europe, and also in Haifa, Israel. The CTCS implemented in Haifa contains enhanced capabilities. While it incorporates the general philosophy of on- and off-line traffic signalization control, the CTCS also coordinates its control strategies with supporting units, namely, electronic signs for drivers, closed-circuit TV system, priority for transit vehicles, and for emergency vehicles. In addition, this CTCS allows for coordination with advanced optimization software aimed at optimal online traffic signalization control, for both congested and uncongested traffic flow situations.<>
