Optimal Locations of Bus Stops Connecting Subways near Urban Intersections

Abstract EN

Unsuitable locations of bus stops which provide feeder transportation connecting subways near urban intersections usually lead to the low efficiency of public transport and level of passenger service.

A multiobjective optimization model to distribute such stop locations is proposed to attain the shortest total walk distance of passengers and minimum delay time of cars through intersections and travel time of buses.

The Pareto frontier and optimal solutions for the proposed model are given by the distance-based and enumerative methods.

The Xizhimen bus stop is selected to implement case studies for verifying the validity of the proposed model.

The analysis of sensitivity on possible solutions is also carried out in the case studies.

The results show that the proposed model is capable of optimizing the locations of bus stops connecting subways near intersections and helpful to improve the level of passengers service and operational efficiency of public transportation.
