Creating Bus Timetables Under Stochastic Demand

Local bus network is the most popular transit mode and the only availabletransit mode in the majority of cities of the world. increasing the utility of thismode which increases its share from urban trips is an important goal for cityplanners. timetable setting as the second component of bus network designproblem (network route design; timetable setting; vehicle assignment; crewassignment) have a great impact on total travel time of transit passengers.the total travel time would effect on transit utility and transit share of urbantrips. one of the most important issues in timetable setting is the temporalcoverage of service during the day. the coverage of demand is an objectivefor setting timetables which has not been well studied in the literature. in thispaper a model is developed in order to maximize the temporal coverage of busnetwork. the model considers demand variation during the day as well as thestochastic nature of demand. a distribution function is used instead of adeterministic value for demand. the model is then implemented to animaginary case.
