Abstract
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.
Highlights
The demand of urban traffic in China has been dramatically increasing with the rapid development of economy, urbanization, and mobilization for last decades
Severe traffic congestion is challenging to the operation and management of urban traffic
More people have realized that urban public transit is an effective way to mitigate traffic congestion and improve the sustainability of transport development
Summary
The demand of urban traffic in China has been dramatically increasing with the rapid development of economy, urbanization, and mobilization for last decades. Due to reliable running time, efficient transport service, and energy consumption, urban rail transit which can carry a great number of passengers has been playing a very important role as the skeleton of urban traffic system. The efficiency of urban rail transit depends on its operational performance and on good cooperation with other transportation modes, especially with those buses which are able to provide feeder service for passengers arriving at or leaving urban rail stations. As the connecting points between buses and urban rail transit services, are important spaces for passengers to alight or board [1]. The bus stops near intersections are often considerable for passengers transferring between urban rail transit and buses, which have a great impact on level of passenger service and attraction of public transit. The above three criteria reflect the interests of different stakeholders involved in operators (bus companies), bus users (passengers), and other users (private cars, taxis), respectively, which are imported into this study
