Evaluation Method for Supply and Demand Matching in Subway-Bus Transfers:A Case Study of Shenzhen City
Realizing convenient transfers between subway and regular bus systems is fundamental to advancing the integration and development of these two transportation networks,which is crucial for constructing a multi-modal and accessible public transportation system.This paper takes Shenzhen as a case study and innovatively combines mobile phone signal data with IC card data to identify the transfer characteristics between subway and regular bus systems.These characteristics include temporal and distance aspects,which effectively illustrate the daily travel patterns of transfer passengers.Through a detailed analysis of the overall transfer characteristics,this study establishes a distance threshold to estimate potential transfer demand and the gap in transfer demand at each subway station.Furthermore,this paper uses the Entropy Weight-TOPSIS Model to conduct a preliminary evaluation of the transfer supply conditions at various subway stations.Based on the evaluation results of the matching between transfer supply and demand,as well as the size of the transfer demand gap,this study proposes corresponding optimization strategies for subway stations,providing an effective method for identifying inefficient stations.The research findings indicate that,in Shenzhen,the subway stations with high potential demand for transfers to regular buses are mainly located near densely populated residential areas.The central urban area exhibits a high degree of matching between transfer supply and demand,with some old urban areas experiencing an oversupply due to the well-developed public transportation infrastructure.However,peripheral stations commonly face a situation where demand exceeds supply,necessitating focused attention on improving transfer supply conditions at these sites.Regarding the transfer demand gap,even among subway stations with the same level of transfer supply,variations in the size of the demand gap exist.Stations with insufficient transfer supply but efficient operations offer valuable lessons,while stations with large demand gaps and inefficient operations should be targeted for specific improvements based on their individual supply and demand matching situations.The results demonstrate that evaluating the alignment between potential subway-bus transfer demand and the level of transfer supply using multi-source data,and formulating optimization strategies in conjunction with the transfer demand gap,is of significant importance for enhancing the refined management level of subway and bus transfer services.Overall,the theory and calculation methods of transfer potential demand and transfer demand gap proposed in this study provide a new perspective and reference for transfer research,public transport planning,and urban planning in the field of public transportation.
