Improving Timetable Quality in Scheduled Transit Networks
نویسندگان
چکیده
This work deals with an original problem with regard to the traditionally sequential planning process in public transit networks. This problem aims at modifying the network’s timetables without rendering the vehicle and driver schedules obsolete. The objective is to improve the quality of service for passengers through number and quality of transfers. This approach goes in the opposite direction compared to the usual approach which schedules resources once timetables are set. We propose a model and a solution method based on tabu search and a neighborhood specifically developed. Experiments are led on five instances related to a real transit network. Important gains are obtained on the considered case study, allowing for better mobility of users inside the network and on the intermodal level.

A Transit Assignment Model on Stochastic Networks
In this paper, a transit assignment model has been developed on stochastic networks, with considering vehicle capacity and scheduled timetable. The stochastic network based transit assignment model is appropriate to apply for bus and metro networks altogether since it can distinguish between uncertain and reliable travel times characteristics by imposing stochastic parameters on links or lines....
متن کاملDemand-oriented timetable design for urban rail transit under stochastic demand
In the context of public transportation system, improving the service quality and robustness through minimizing the average passengers waiting time is a real challenge. This study provides robust stochastic programming models for train timetabling problem in urban rail transit systems. The objective is minimization of the weighted summation of the expected cost of passenger waiting time, its va...
متن کاملA Novel Method for Measuring the Quality of Temporal Integration in Public Transport Systems
Temporal coordination of services, as a crucial aspect of integration in public transport systems, has always been a big concern for transit planners and schedulers. One of the major issues in the way of coordinating transit services is the lack of a robust measure of effectiveness for assessing the quality of temporal coordination in public transport systems. Even though the network-wide summa...
متن کاملCreating Bus Timetables Under Stochastic Demand
Local bus network is the most popular transit mode and the only available transit mode in the majority of cities of the world. Increasing the utility of this mode which increases its share from urban trips is an important goal for city planners. Timetable setting as the second component of bus network design problem (network route design timetable setting vehicle assignment crew assignment) hav...
متن کاملIs Timetabling Routing Always Reliable for Public Transport?
Current route planning algorithms for public transport networks are mostly based on timetable information only, i.e., they compute shortest routes under the assumption that all transit vehicles (e.g., buses, subway trains) will incur in no delays throughout their trips. Unfortunately, unavoidable and unexpected delays often prevent transit vehicles to respect their originally planned schedule. ...
