【摘要】 为提高交通拥堵治理工作的精细化管理水平,并为城市内部街道社区级行政区域提供交通评价方法,解决交通运行评价指标的评价维度细化问题,设计了适用于街道级小区域的交通指数计算方法。首先总结国内外交通运行评价指标研究现状,引出城市动态交通运行的评价指标,以及对于评价指标的评价效果的判定指标。然后建立街道级小区域的交通指数计算方法,通过比较不同评价指标计算基础之间的区别,选择出了适用于评价街道级小区域的交通特征性评价指标;参考学者的研究,建立了有效样本路段的筛选准则,对评价街道级小区域城市道路网进行筛选;通过比较小区域交通运行状态的评价时间粒度,结合判定指标结果,选择出适合于街道级小区域交通运行状态评价标准的评价时间粒度;结合上述计算算法设计出小区域交通指数计算方法。最后以北京市中心城六区为例,对算法进行了案例分析,并将小区域交通指数反映出来的交通特征与街道社区的交通特征进行对比分析。案例计算结果表明:该方法可以较准确的表达街道级小区域的交通运行特征。更多还原

【Abstract】 In order to improve the fine management level of traffic congestion control work, provide traffic evaluation method for urban administrative region of residential districts, and solve the problem of refinement of evaluation dimensions of traffic operation evaluation indicators, a traffic indicator calculation method suitable for residential districts is designed. First, we summarized the research status of traffic operation evaluation indicators at home and abroad, and introduced the evaluation indicators of urban dynamic traffic operation and the criterion of the evaluation effect of the evaluation indicators. Then, we established the calculation method of traffic indicator for residential districts, and selected the traffic characteristic evaluation indicators suitable for evaluating residential districts after comparing the difference between the calculation basises of different evaluation indicators. Referring to the researches of scholars, we established the screening criteria of effective sample sections, and screened the urban road network of the evaluated residential districts. By comparing the evaluation time granularities of traffic operation status of the residential districts and combining with the result of criterion, we selected the evaluation time granularity suitable for the evaluation criteria of traffic operation state of residential districts, and designed the calculation method of residential district traffic indicators based on the above calculation method. Finally, taking 6 districts of Beijing central city for example, we analyzed the calculation method by case study, and compared the traffic characteristics reflected by the traffic indicator of the residential districts with those of street community. The result of case calculation shows that this method can accurately express the traffic operation characteristics of residential districts.更多还原
