DESIGN ANALYSIS OF STATIONS AND INTERSECTIONS OF HIGH-CAPACITY PERSONAL RAPID TRANSIT NETWORK

This paper describes an effort to develop geometric designs for high-capacity personal rapid transit links, stations, and intersections and to predict and evaluate their performance under quasi-synchronous control at different design and operating conditions. The system assumed 1-way routes and vehicle accelerations and decelerations only on the off-lines. The geometric design of off-lines at stations and intersections considers recommended normal and centripetal acceleration and jerk rates, allowable radius of curvature, required maneuver zone length, and required capacity of the off-line and the line spacing chosen. Typical conditions for a large urban area are considered. In the PRT system, vehicle queues are formed on the upstream and downstream sides of station platforms and intersection turns. The modeling, analysis, and simulation of these queues are described. The excess capacities and the sizes of queuing zones needed can be obtained from simulation results for stations and intersections of different capacities. The resulting average waiting time, the probability of vehicle rejection on the upstream side, the probability of forced switching to prevent the stopping of vehicles on the downstream side, and the achievable guideway density are given as functions of design and operating parameters. The possible trade-offs among design capacity, traffic density, length of queuing zone, and user costs involved at stations and intersections are discussed.
