Title:

Capacity of PRT Station Capacity

Abstract:

Approaches to maximize the throughput of personal rapid transit (PRT) stations under peak demand conditions are examined. Stations must be designed consistent with the limitations of the guideways they serve. It is shown that simple algebraic models can provide key insights into the design issues and limitations. The key design issue is the overall berth cycle time, including time for: door opening, passenger load or unload, door close time, trip initiation, and vehicle resupply. Measured data on the times for passenger loading on the ULTra vehicle are presented. Elapsed loading times are found to be dominated by the door opening times of 10 seconds. Passenger loading times, ignoring door opening and closing, are small, 4.4 seconds for 1 passenger and 8.2 seconds for 4. Unloading times reduce to 3.2 seconds for 1 passenger and 5.4 seconds for 4. These short times are consistent with published data on loading and unloading in other transit situations. Some possible station designs are shown. These have been designed to meet objectives of combining minimum size with maximum capacity. New station designs featuring forward rather than reversing berths provide a benefit in capacity at the expense of some increase in size. It is found that a 5 berth station with current levels of PRT technology can be expected to provide a capacity of 600 vehicles per hour, each loading 4 people. Delivered passenger clearance rates of one every 1.5 seconds compare favorably with bus loading rates of one every 2.5 seconds
