基于城市居住区POI数据的昆明市公共交通站点可达性分析

Accessibility Analysis of Public Transportation Sites in Kunming Based on POI Data of Urban Residential Areas

本文利用2016年昆明市主城五区的POI数据,采用GIS分析工具,构建昆明市可达性分析模型,基于昆明路网建立步行交通网络数据集,通过最小阻抗和出行范围的两种可达性评价展开研究。通过针对服务于居民的居住区片区公共服务设施的空间布置方法,尝试通过考虑交通的转弯和通达性、时间成本以及距离等因素进行可达性分析,以昆明市公交站点和住区点为基础对昆明市公共交通可达性进行分析评价。

This study uses the POI data of the five districts of the main city of Kunming in 2016,uses the GIS analysis tool to construct the accessibility analysis model of Kunming,and establishes the pedestrian traffic network dataset based on Kunming Road Network,which can pass the minimum impedance and the range of travel.The evaluation of the achievement was carried out.Through the spatial arrangement method of the public service facilities in the residential area of the residential area,the accessibility analysis is carried out by considering the turning and accessibility of the traffic,time cost and distance,etc.,based on the bus station and residential area of Kunming.Analyze and evaluate the accessibility of public transportation in Kunming.
