摘　　要：为提高城市区域路网交通运行状态评价的准确性,选取平均行程速度、时间占有率、交叉口饱和度、每车平均延误、平均最大排队长度作为评价指标,将城市区域路网交通运行状态划分为优良差劣4个等级.考虑不同时间节点对路网交通整体运行状态影响的差异,应用基于动态综合评价的城市区域路网交通运行状态评价方法,对天津市高新区路网进行动态评价.结合现行规范标准确定各评价指标的阈限值,根据实测交通数据确定不同时段路网交通状态等级;根据评价结果提出关键路段交叉口信号优化方案,应用动态综合评价法对仿真结果进行验证.结果表明本文提出的评价指标与评价方法可有效判别区域路网交通运行状态.To improve the accuracy of the evaluation on the traffic operation status of the road network in urban areas,the average travel speed,time occupancy,intersection saturation,average delay per vehicle,and average maximum queue length were selected as the evaluation indicators,and the traffic operation status of the road network in urban areas was divided into four levels:excellent,good,average and poor.Considering the differences in the influence of different time nodes on the overall operation status of road network traffic,this study applied the evaluation method of urban regional road network traffic operation status based on dynamic comprehensive evaluation to dynamically evaluate the road network of Tianjin High-tech Zone.Combined with the current norms and standards,the threshold limit value of each evaluation index was determined,and the traffic status level of the road network at different times was determined according to the measured traffic data.According to the evaluation results,the signal optimization scheme of key road sections was proposed,and the dynamic comprehensive evaluation method was applied to verify the simulation results.The results show that the evaluation index and evaluation method proposed in this paper can effectively determine the traffic operation status of regional road network.
