摘　　要：为实现大规模城市路网下的交通运行效率评估,立足于深圳市福田区、南山区以及罗湖区的浮动车轨迹数据,提出了一种结合交通可达性与道路交通流特性的评价方法。通过地图匹配与网络重构获得路网重构图,对其进行社区发现与聚类以挖掘路网内在联系并进行交通运行效率评价。该评价方法兼顾路网结构与交通属性,在考虑路网内在关联性的情况下进行城市路网交通效率评价,并通过评价结果对实际路网提出针对性改进建议。相比传统方法,该文提出的评价方法能够识别出道路间相互影响关系,在局部路网的尺度下修正评价结果,使评价结果体现出实际路网不同区域内交通效率的内在联系。In order to realize the evaluation of traffic efficiency under the large-scale urban road network,based on the floating car data of Futian District,Nanshan District and Luohu District of Shenzhen,this study proposed an evaluation method combining traffic accessibility and road traffic flow characteristics,and obtained the reconstructed road network through map matching and network reconstruction.Community discovery and clustering are carried out to explore the internal connection of the road network and evaluate the traffic efficiency.This evaluation method takes into account the road network structure and traffic attributes,evaluates the traffic efficiency of urban road network under the condition of considering the internal correlation of road network,and propose targeted improvement suggestions for actual road network through?E evaluation results.Compared with the traditional method,the evaluation method proposed in this paper can identify the interaction between roads and modify the evaluation results under the scale of the local road network,so that the evaluation results can reflect the internal relationship between the traffic efficiency in different areas of the actual road network.
