I-95/NW 7TH AVENUE BUS/CAR POOL SYSTEMS DEMONSTRATION PROJECT REPORT I-8. EFFECT OF THE BUS PRIORITY SYSTEMS OPERATION ON PERFORMANCE OF TRAFFIC SIGNAL CONTROL EQUIPMENT ON NW 7TH AVENUE

This report deals with the effects of a bus preemption system on the traffic control system operation on NW 7th Avenue in Miami. The quantities examined in detail were the operating parameters of the signal system, i.e., cycle length, bus phase length, non-bus phase length, etc. Substantial variation in these parameters was found throughout the course of the Project. However, most of the variation was attributable to misoperation of detectors and other signal equipment and to changes in the design parameters which were necessary throughout the course of the Project. The bus preemption system performed satisfactorily from a reliability point of view. No difficulties were experienced either with the failure to recognize buses or with false alarms. Preemption equipment problems accounted for only 3 percent of the maintenance calls. The traffic control system itself, however, presented somewhat of a maintenance problem. The rate of maintenance calls for this particular system was approximately double the county-wide average. The introduction of the computerized signal system on NW 7th Avenue compounded the general maintenance problem.
