The U. S. Department of Transportation/Urban Mass Transportation Administration (DOT/UMTA) is developing an automatic vehicle monitoring (AVM) system which will accommodate both fixed and random-route users. This is a two-phase program. Phase I is testing four location subsystems in Philadelphia. Phase II contemplates selecting one contractor to develop, fabricate, install, and test a completely functional system that can be shared by users with diverse requirements. Location subsystems fall into one of four general categories: signpost, radio frequency, dead-reckoning, or a hybrid system of some combination of the first three. Within each type, subtypes exist. The objectives of the DOT/UMTA system are to 1) develop and deploy a multiuser AVM to improve the level of service, safety, and efficiency of bus service, and improve the dispatch efficiency of random-route vehicle fleets; 2) quantify the benefits to transit and other users; and 3) establish technical and economic bases for future AVM deployments. The AVM system performance specifications contained in the DOT Request for Proposals consist of system capacity, location accuracy, communication, data processing and display, and an overall system specification.
