I-95/NW 7TH AVENUE BUS/CAR POOL SYSTEMS DEMONSTRATION PROJECT REPORT I-6. EFFECTS OF NW 7TH AVENUE BUS PRIORITY SYSTEMS ON NW 7TH AVENUE TRAFFIC STREAM FLOW AND PASSENGER MOVEMENTS

The purpose of this report was to document the effects of several bus priority systems implemented on NW 7th Avenue in Miami, Florida, on traffic stream flow and passenger movement characteristics. Data were collected regarding traffic volume, vehicle occupancy, system delay (air photos), violations of the reserved lane, auto travel time and accidents. Analyses were conducted to determine the effects of each bus priority system on the operational characteristics of automobile traffic and passenger movements on NW 7th Avenue. Some of the general conclusions were: (1) none of the implemented bus priority systems produced an adverse effect on auto traffic and, in fact, the auto traffic was generally improved under all bus priority systems; (2) the bus priority system consisting of a reversible, exclusive bus lane and traffic signal progression produced better operation for the automobile traffic than did the systems which used the exclusive bus lane and traffic signal preemption; (3) the initiation of the exclusive lane was associated with a significant increase in bus accident rates; after a 'start up' period, the bus accident rate decreased somewhat but still remained higher than the bus accident rate before the initiation of the bus lane; (4) the rate of violation of the reserved lane was relatively low (about 5%); there was an indication that the violation rate decreased with time as drivers learned of the reserved lane and left turn restrictions.
