TEMPORAL AND SPATIAL DIMENSIONS OF RUNNING TIME IN TRANSIT SYSTEMS. (ABRIDGMENT)

Transit running time is examined during various times of the day, in different directions of travel, and at different points along the route by using empirical data from Cincinnati, Ohio. Simple models relating running time to temporal and spatial dimensions are also reported that could serve as practical transit sketch planning tools. Several conclusions are drawn from the empirical analyses. It was found that transit running times are highest and most variable during the afternoon peak period. Daytime and evening off-peak service also have reliability problems. Finally, regardless of the time period, it is apparent that variation in running time increases with distance from route origin so that service deteriorates as the vehicle proceeds downstream. The implications of these results are that the afternoon peak should be examined more thoroughly in terms of causes of unreliable service and techniques that can be used to improve service predictability. Further research into fluctuations in daytime off-peak travel and the reasons for low predictability of evening off-peak service is also suggested.
