A SUGGESTED MODEL FOR ESTIMATING THE PRACTICAL PERFORMANCE OF TRANSIT SYSTEMS

The model suggested is developed as an exploratory tool for estimating the practical performance of transit systems of both existing and new technologies. A constant jerk-rate type of equation is shown to give excellent agreement with existing New South Wales suburban railway rolling stock. By development of the envelope, use of this equation may be extended to examine the effects of reduced station dwell, increased initial acceleration and increased maximum speed etc. It is shown that for initial accelerations above 5 km/h/s very little benefit is likely to accrue on on suburban systems, but major benefits are likely to stem from increasing station separation, skip-stop scheduling and reduced station dwell, all of which are feasible with existing technology systems. The method is shown to be particularly useful in the estimation of journey speed, journey time and station-to-station time when coding transit networks for modal-split analysis. (A). /TRRL/
