A TELEMETRIC MONITORING AND ANALYSIS SYSTEM FOR USE DURING LARGE SCALE POPULATION EVACUATIONS. SECOND INTERNATIONAL CONFERENCE ON ROAD TRAFFIC MONITORING

This paper describes the on-going development of an operational, prototype real-time traffic monitoring and analysis system (RTMAS) whose purpose is to record and warn of the build-up of significant urban population evacuations in times of threat. In tracking an evacuation build-up, RTMAS is being developed to collect and cumulate net traffic movements (i.e. Net regional outflows), building up a quantitative picture of the timing and directions of an evacuation. The system runs on an IBM PS2/model 80 microcomputer. Traffic counts are brought into rtmas via modern and conventional telephone lines, using software initiated direct dial-up to each traffic counter in turn. Four major software components are utilized (Guru, Autobox, Crosstalk, and a traffic pattern recognition program). A fifth component, a dynamic network traffic assignment model, used to simulate the selection of evacuation routes, and to update its predictions during the course of an evacuation, is under development. Details of Guru, Crosstalk and Autobox are provided, as is a description of the methods used to estimate net traffic flows and to select traffic counter locations. (TRRL)
