| 摘 要： | 为提高高速公路交通安全水平,有效利用先进的智能交通设施,分析高速公路可变情报板安全问题和布局策略,建立可变情报板与事件发生点的前置距离模型,提出系统性的可变情报板选址方法.方法综合考虑了特殊路段与事件发生点的安全影响,建立的可变情报板前置距离模型应用元胞传输模型,以相邻元胞速度协调性好为目标,最优化前置距离.最后,以福建省某条高速公路交通事件发生区为算例,算出可变情报板前置距离为268m.计算结果表明,所提出的可变情报板前置距离模型与选址方法有利于可变情报板的合理布局.

| Abstract: | To improve the traffic safety condition in the expressway and make use of the advanced ITS facilities efficiently,the safety problems of variable message signs in the exressway were analyzed and the location strategy was illuminated. Then the model of distance between variable message sign and incident point was brought forward. A systematic location selection method for variable message signs was advanced. The method considered the safety impact of particular highway segments and incident points. The cell ... |
