ABSTRACT
This chapter contains four main parts. First, I address and formulate the problem of generating headway-based timetables, in which the number of simultaneous vehicle arrivals at connection (transfer) points is maximized. This is a maximum synchronization problem in time and space that is meant to enable the transfer of passengers from one route to another with minimum waiting time at the transfer points. Second, a heuristic procedure (i.e. a procedure or algorithm that does not result for sure in an optimum solution) is proffered, in which the setting of departure times follows efficient rules. Third, I improve the results (i.e. increasing the number of meetings between vehicles on different routes) by allowing a shift in departure time within given boundaries. This improvement uses defined efficient rules imbedded in the second heuristic procedure. Fourth, I provide detailed examples to illustrate the two proposed procedures explicitly. These examples follow the two procedures step-by-step and can help practitioners gain a better grasp of the analysis and results. Overall, this chapter asserts that, basically, a non-coordinated transit network is simply the unfolding of a miscalculation.
