基于GIS空间分析的交通劣势区识别

Transport Disadvantage Area Identification Based on GIS Spatial Analysis

以许昌市魏都区为研究区域,以下辖街道为基本研究单元,以路网密度、交通干线影响度、区位优势度、500 m交通站点覆盖率4个指标集成交通劣势风险评价体系。运用ArcGIS空间分析,交通劣势风险值识别出交通劣势区,并对识别结果进行评价分析,提出发展建议和措施。结果显示:魏都区的交通劣势区为许昌经济开发区和丁庄街道,潜在交通劣势风险区为高桥营街道、七里店街道和半截河街道。根据4个评价指标的分析结果,对魏都区未来发展规划提出建议。

Weidu District in Xuchang City is taken as the research area and its subdistrict is the basic research unit.Road network density,impact degree of traffic arteries,location predominance degree,and 500m coverage rate of transport stops are integrated into the risk value of transport disadvantage.Spatial analysis in ArcGIS is applied to identify the transport disadvantage area based on the risk value of transport disadvantage.The development suggestions and measures are put forward based on the identification results analysis.The results show that the transport disadvantage areas of Weidu District are Xuchang Economic Development Zone and Dingzhuang Street.The potential transport disadvantage areas are Gaoqiaoying Street,Qilidian Street,and Banjiehe Street.According to the analysis results of four evaluation indicators,this paper proposes useful suggestions for future development planning of Weidu District.
