| 摘 要： | 利用基于交通冲突的洛巴诺夫安全评价模型，对交通量在高峰小时超过10 000辆的四相位信号控制交叉口进行安全评价.根据冲突点的分布、交叉口特性及vissim仿真的交通流量确定模型的参数值；通过分析每个冲突点和整个交叉口的危险度，针对交叉口的特性提出了可靠的安全改善措施，并利用vissim对改善后的交叉口进行危险度仿真评价.作为实例验证，应用评价模型对济南经十纬十二交叉口进行了危险度评价.

| Abstract: | According to the Lebanon safety assessment model based on traffic conflict,this paper evaluates the safety of the 4-phase signal control intersection with more than 10,000 traffic volume during peak hours.It then determines the model parameters considering the distribution,type of conflict points and infrastructure characteristics and the traffic flow obtained by VISSIM simulation.The risks of each confliction and the entire intersection are analyzed and some measures are put forward to improve the intersection safety.The risk for the improved intersection is evaluated by VISSIM simulation.The case study of the intersection of Jingshiwei twelve in Jinan city is then conducted. |
