Accessibility Optimization of Public Transportation in Historical Districts—A Study of Bei’lin District, Xi’an
Publication: CICTP 2023
ABSTRACT
With continuous improvement of urbanization and motorization, travel demand in historical blocks is higher than before. The contradiction between supply of transportation facilities and environmental protection is more serious. Traditional public transport planning methods aim to improve mobility. However, several existing studies do not put travelers at the first place, which ignore quantitative description of land uses and the characteristics of travelers. This paper intends to improve individual accessibility of public transportation in historical districts. Based on POI data, the calculation of accessibility combines the utility model and spatial interaction model. To optimize public transportation, the goal of improving individual accessibility is transformed into reducing residents’ travel negative utility. Using a real-world dataset in Bei’lin District of Xi’an, the performance of the proposed model is evaluated. This paper calculates the present accessibility and uses ant colony algorithm to optimize public transportation. The results demonstrate that the calculation and optimization of public transportation accessibility are practical, which are also valuable to public transportation planning and organization in historical blocks.
