摘要
为了保障公路施工区的交通安全,通过分析施工区不同区段的安全状况,提出了以冲突率和速度偏差变化系数作为安全评价指标,并构建VISSIM仿真模型,根据有限的交通信息,运用灰色聚类法对施工区各区段进行冲突率和CVSD指标的安全评价。所得结果能够反映施工区各区段的总体安全程度,进而为公路施工者提供改进的依据。
In order to improve the traffic safety of highway work zone, the security situation of different sections of work zone was analyzed. The security evaluation indices based on collision rate and coefficient of variation of the speed deviation were put forward. The VISSIM simulation model was built. Based on limited traffic information, gray clustering method was used to evaluate the safety in work zone of each section with collision rate and CVSD. The results reflect the overall security level of work zone and provide road builders with improvement basis.
