Microcomputer Based Traffic Control System Monitoring and Enhancement. Executive Summary

摘要

Four procedures were developed to enhance the operation of microcomputer based traffic control systems: (1) A procedure for implementation of traffic signal timing plans directly from design and optimization programs; (2) A procedure for evaluating the trade-off between coordinated operation and isolated operation under late night low volume conditions; (3) A procedure for analyzing real-time detector and signal display status information to produce estimates of traffic volumes and performance measures; (4) A procedure for determining optimal threshold parameters for traffic responsive control. Each of these procedures involves a computerized technique which was developed specifically for that purpose. Each procedure strengthens the link between the traffic engineer and the control system.
