Summary
This document summarizes the Urban Mass Transportation Administration's program to evaluate automatic vehicle monitoring (AVM) systems for transit and law enforcement operations. It reviews the international history of AVM development and details a two-phase UMTA program designed to refine and demonstrate the technology. Phase One involved field-testing four location technology concepts in Philadelphia, while Phase Two focuses on deploying a complete multiuser system in Los Angeles. The report describes system components, including location technologies and digital communications, and outlines the objectives of quantifying costs and benefits. It concludes that AVM offers potential improvements in fleet control, schedule adherence, and emergency response capabilities.
Key finding
The UMTA program successfully demonstrated that various location technologies for automatic vehicle monitoring are feasible for transit and police applications, leading to the deployment of a comprehensive system in Los Angeles for further evaluation.
