基于车路协同技术的城市交通状态评价分析

Evaluation and Analysis of Urban Traffic State Based on Vehicle-Road Coordination Technology

由于受到城市交通时变性和评价过程中的主观性影响,当前现有城市交通状态评价方法得出的评价结果与实际存在较大偏差,评价结果一致性较低,影响评价结果利用价值。针对这一问题,引入车路协同技术,开展对评价方法的设计研究。通过基于车路协同的城市交通状态数据实时获取、城市交通状态评价指标参数选择与评价体系建立、城市交通状态等级层次化评价与分析,提出一种全新的评价方法。通过对比实验证明,新的评价方法与以往评价方法相比,得出的结果与实际城市交通状态变化趋势一致,评价结果一致性更强,可为城市交通协同管理提供更有利的评价依据。

Due to the temporal variability of the current urban traffic and the subjectivity of the evaluation process,the evaluation results obtained by the current existing urban traffic state evaluation methods have large deviations from the reality,which makes the evaluation results less consistent and affects the utilization value of the evaluation results.In response to this problem,the vehicleroad collaboration technology is introduced to carry out the design research on the evaluation method.Through the real-time acquisition of urban traffic state data based on vehicle-road collaboration,the selection of urban traffic state evaluation index parameters and the establishment of an evaluation system,and the hierarchical evaluation and analysis of urban traffic state levels,a new evaluation method is proposed.Through comparative experiments,it is proved that the results obtained by the new evaluation method is consistent with the actual urban traffic status change trend compared with the previous evaluation method,and the evaluation results are more consistent,which can provide a more favorable evaluation basis for the coordinated management of urban transportation.
