Train rescheduling model with train delay and passenger impatience time in urban subway network

摘要

This paper considers the train rescheduling problem with train delay in urban subway network. With the objective of minimizing the negative effect of train delay to passengers, which is quantified with a weighted combination of travel time cost and the cost of giving up the planned trips, train rescheduling model is proposed to jointly synchronize both train delay operation constraints and passenger behavior choices. Spacea??time network is proposed to describe passenger schedulea??based path choices and obtain the shortest travel times. Impatience time is defined to describe the intolerance of passengers to train delay. By comparing the increased travel time due to train delay with the passenger impatience time, a binary variable is defined to represent whether the passenger will give up their planned trips or not. The proposed train rescheduling model is implemented using genetic algorithm, and the model effectiveness is further examined through numerical experiments of reala??world urban subway train timetabling test. Duration effects of the train delay to the optimization results are analyzed. Copyright ?? 2017 John Wiley & Sons, Ltd.
