基于GIS的公交换乘网络构建及可达性分析.

To improve the bus transfer efficiency and optimize the bus system, the bus transfer network was constructed based on GIS software, and the network was used to measure and analyze the transfer accessibility. Combined with Space-P model and network analysis method, the same-station transfer sub-network was constructed based on the basic information of bus route paths, stations and intersections in Chengguan District of Lhasa City. Combined with the information of bus station service scope, pedestrian. path and intersection, the different-station interchange sub-network was constructed. The two sub-networks were collaborated to realize the construction of bus transfer network based on ArcGIS, and the passenger on-board time and the transfer coefficient of bus routes were measured and analyzed based on the constructed transfer network. The results show that the constructed network can measure the passenger on-board time well, and the maximum value of passenger on-board time is 68.68 min with the minimum value of 2.00 min and the average value of passenger transfer on-board time of 29.90 min. This network can well measure the interchange coefficients to obtain 90 300 effective interchange routes with the maximum interchange coefficient of 4 (62 routes) and the minimum value of 0 (1354 routes). Using the accessibility metric model, the good measurement and analysis of bus stop time accessibility and transfer accessibility can be realized. [ABSTRACT FROM AUTHOR]
