考虑个人出行意愿及出行需求的区域公共交通可达性分析

Analysis of regional public transport accessibility considering personal travel willingness and travel demand

综合考虑个人出行意愿阈值、不同时段居民出行需求以及相关可达性评价指标,建立城市区域公共交通可达性模型。以哈尔滨南岗区为研究对象,通过手机信令数据提取出行需求数据,并在出行阈值的条件下基于高德地图API接口获取实时可达性评价指标,计算各交通小区区域公共交通可达性水平。研究结果能较全面地综合反映城市区域公共交通系统的可达性水平,为规划城市公共交通网络、优化公交线网布局、解决城市交通问题提供参考。

This paper comprehensively considers the threshold of personal travel willingness,residents’travel needs in different time periods,and related accessibility evaluation indicators to establish an urban regional public transportation accessibility model.Taking Nangang District of Harbin as the research object,the travel demand data is extracted through mobile phone signaling data,and the real-time accessibility evaluation index is obtained based on the API interface of AutoNavi map under the condition of travel threshold is obtained to calculate the accessibility level of public transportation in each traffic area.The research results can comprehensively reflect the accessibility level of urban regional public transport system,and provide a basis for urban public transport network planning,bus optimization and solving urban traffic problems.
