TL;DR: In this article, the authors describe an algorithm for scheduling passenger transportation systems under the realization that travel demand will both vary with time of day and depend on the schedule, using a combination of dynamic programming and heuristic search to generate scheduling policies which attempt to balance the demand attracted and served against the costs of attracting and serving this demand in a manner consistent with the system's objective.
Abstract: This report describes an algorithm for scheduling passenger transportation systems under the realization that travel demand will both vary with time of day and depend on the schedule. The control variables used are the number of departures per day on each link, the times of these departures, and the number of units dispatched at each departure. The algorithm uses a combination of dynamic programming and heuristic search to generate scheduling policies which attempt to balance the demand attracted and served against the costs of attracting and serving this demand in a manner consistent with the system's objective. The algorithm can accept a wide variety of demand models and objective functions and may be feasibly applied to networks containing several hundred links.

TL;DR: In this article, a flow field about an internally propelled vehicle in steady motion at subsonic speed, analyzed by method of characteristics, is presented. But the analysis is limited to the case of a single-passenger vehicle.
