Annotation: THIS REPORT DESCRIBES A COMPREHENSIVE TEST OF A DIRECT PROXIMITY ELECTRONIC SIGNPOST AVM SYSTEM WHICH WAS CONDUCTED UNDER OPERATIONAL CONDITIONS IN DOWNTOWN PHILADELPHIA.
Abstract: TESTS INVOLVED OPERATION OF A TEST VEHICLE AS A RANDOM ROUTE VEHICLE (POLICE, TAXI) AND FIXED ROUTE VEHICLE (A TRANSIT BUS). DURING RANDOM ROUTE TESTS, THE VEHICLE OPERATED ON AN UNRESTRICTED BASIS IN A DESIGNATED AREA IN WHICH THE HOFFMAN OVERLAPPING SIGNPOST AVM SYSTEM WAS INSTALLED. THE VEHICLE'S LOCATION WAS COMPUTED EVERY 0.5 SECONDS BY THE AVM SYSTEM AND COMPARED WITH ITS ACTUAL LOCATION AT DESIGNATED 'CHECKPOINTS' IN THE RANDOM ROUTE AREA. 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 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 'TIMEPOINTS' WAS AUTOMATICALLY DETERMINED TO WITHIN 11 SECONDS, 95 PERCENT OF THE TIME. VOLUME II IS AN APPENDIX CONTAINING THE TEST DATA AND DETAILED DATA PROCESSING RESULTS. (AUTHOR ABSTRACT MODIFIED)
