Abstract:The report covers the activities of Phase I which involved the installation and test of a HI3 AVM System in Philadelphia, Pennsylvania, during the winter of 1976-1977. A summary report on all systems tested is Experiments on four different techniques for automatically locating land vehicles (PB-270 951). Phase I tests were divided into two primary categories: (1) random-route tests (police, paratransit, taxi, etc.), and (2) fixed-route (transit). In the random-route tests, the system showed the capability of locating the vehicle to within 282 feet, at 95 percent of the sample points under a wide range of urban and environmental conditions. In the fixed-route tests, an odometer and 15 signposts provided the vehicle's location to within 105 feet at 95 percent of the sample points along a 13-mile route. The time of passage of designated bus schedule 'timepoint' was automatically determined to within 11 seconds 95 percent of the time. Phase I consists of two volumes: Volume I: Test Results contains a description of all test configurations, test procedures, location algorithms, data processing, and test results; Volume II: Appendix contains the test log sheets, test data, and data processing results corresponding to all Phase I tests.
