【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。
[Abstract]:In order to study the traffic risk of the upstream transition section of the construction area and ensure the traffic safety of the construction area, the Vissim simulation software is used to simulate the running state of the traffic flow in the construction area, and the length and the traffic volume of the transition section are analyzed. The influence of driving speed on driving risk in construction area; The conflict rate is used as the evaluation index, the traffic risk is divided into five grades, and the fuzzy comprehensive evaluation theory is used to evaluate the traffic risk. The results show that the length of the transition section and the traffic volume are the most important factors affecting the traffic risk in the upstream transitional section of the construction area, and the degree of influence exceeds 90%. Therefore, reasonable control of the length of the transition section and traffic volume plays an important role in reducing the traffic risk in the construction area.
