Descripción
The railway planning process, due to its complexity, is commonly divided in a set of successive stages comprising network design, line planning, scheduling, timetabling, rolling stock and personnel scheduling. From a practical point of view, frequencies are line by line obtained following a regular double direction schema with constant headways. After this, a synchronization process is followed to improve connectivity among lines. In the past few years a set of acceleration strategies for managing these congestion problems have attracted increasing interest, mainly those based on controlling the frequency of vehicles at stops (e.g. the so called short-turning and deadheading approaches). Usually, the output of these models is an optimal frequency plan including new cycles and deadheading trips between various critical stations. After this stage, the frequency plan should be finally converted into a concrete and compatible train schedule containing departure and arrival vehicle times at stops. This process can be viewed as a location problem where each service is represented as segment to be located in a time-space diagram subject to certain sets of constraints. In this paper we resent general integer linear programming model in order to obtain such schedules for a given frequency distribution previously obtained and taking into account network capacity and safety constraints with the objective of preserving regularity as much as possible.
