摘　　要：为了研究施工区上游过渡段的行车风险,保障施工区的行车安全,应用Vissim仿真软件模拟施工区交通流的运行状态,分析过渡段长度、交通量、行驶速度对施工区行车风险的影响;利用冲突率作为评价指标,将路段行车风险分为5个等级,运用模糊综合评判理论进行综合评判。研究结果表明:过渡段长度、交通量是影响施工区上游过渡段行车风险最主要的因素,影响程度超90%,因而合理控制过渡段长度和交通量对降低施工区行车风险具有重要作用。In order to study the driving risk of the upstream transition section of the construction area and to ensure the traffic safety of the construction area, the Vissim simulation software was used to simulate the operation status of the traffic flow in the construction area, and the influence of the transition section length, traffic volume and driving speed on the driving risk was analyzed. Using the conflict rate as the evaluation index, the road traffic risk was divided into five grades, and the fuzzy comprehensive evaluation theory was applied to conduct a comprehensive evaluation. The results show that the length of the transition section and the traffic volume are the most important factors influencing the traffic risk of the transitional section in the upstream of the construction area. The influence degree is over 90%. Therefore, it is important to control the length of the transition area and the traffic volume to reduce the traffic risk.
