摘要
为了合理分析城市公共交通发展现状并对其发展提供可参考的依据,本文利用地理信息系统空间分析和统计方法,在确立多个评价指标的基础上,对城市公共交通覆盖度情况进行不同角度、不同方面的评价。以沈阳市内部分区域为研究对象,提取研究区域基础地理数据,结合人口数据以及公共交通线网缓冲区,选取城市主次干道为边界划分分析单元,将人口密度与道路数据相结合,将评价体系与数据进行对比分析。根据评价指标,得到研究范围内城市公交资源的分布状况。实验结果表明,该方法能够较好地分析城市公共交通分布特征,为城市交通规划设计提供思路。
In order to analyze the status quo of urban public transport development and better use of geographic information system spatial analysis methods,select a different level,more aspects of the evaluation,assessment of spatial coverage of urban public transport,the grading and quantitative indicators and threshold analysis is complete. Taking part of Shenyang city as the research object,extracting the basic geographic data of the study area,combining the population data and the public transportation network buffer,selecting the urban primary and secondary trunk road as the boundary division analysis unit,using the population density distribution characteristics for spatial analysis,and It is unified into the analysis unit. According to the established spatial coverage evaluation index system,the public transportation spatial coverage evaluation index of the study area is calculated,and the indicators of the analysis unit are evaluated according to the classification threshold,thereby reflecting the spatial communication of the research area public transportation resources. Distribution characteristics. The experimental results show that the method can better analyze the distribution characteristics of urban public transportation and provide ideas for urban transportation planning and design.
