| 摘 要： | 为了制定安全高效的应急疏散预案,分析了SCOOT和BOTTLENECK算法的适应性,提出一种基于路口和路段入口综合控制的优化算法.新算法利用SCOOT算法对路口进行信号协调控制,利用BOTTLENECK算法对路段入口交通进行汇入控制,并通过严格控制延误目标将两种算法进行优化整合,确保主要疏散方向上的优先通行权,同时减少汇入交通对疏散车辆的干扰和延误,从而最大限度挖掘路网在应急状态下的疏散通行能力.仿真结果表明:在应急疏散交通条件下采用优化算法,能够将疏散车辆平均行程时间缩短近60%,平均速度提高约1.5倍,因此,提高了应急疏散效率,算法可行.

| Abstract: | In order to establish an efficient predetermined plan of emergency evacuation,the adaptabilities of SCOOT and BOTTLENECK algorithms were analyzed,and an optimal algorithm was proposed based on the integrating control of signal intersections and arterial accesses.New algorithm controlled signal intersections with SCOOT algorithm,and controlled entering traffic at arterial accesses with BOTTLENECK algorithm.In order to insure the routing priority of main evacuation direction,the two algorithms were optimized ... |
