통행 배정을 고려한 철도 노선 계획 최적화 모형

초록

Most line planning models in railway network assume that demands for each train-type are in advance given from a transit assignment model such as 'system split'. System split is a procedure to distribute passenger demands over an entire network. This distribution is based on a value assigned to a route which is primarily determined from the total travel time, the number of transfers and maximum headway (or minimum frequency) of a route. However Such stepwise approaches have a critical shortcoming that the line frequencies assumed in transit assignment does not coincide with the line frequencies found by line planning model. Such inconsistency results in inaccurate demand and line frequencies. We present a new line planning model considering stochastic transit assignment in order to overcome the inconsistency between line plan and transit assignment.
