| 摘 要： | 为了研究车道分配对路网容量的影响,通过分配道路的双向车道数和设置交叉口的信号配时参数,建立了双层规划的路网备用容量模型.上层模型用于路网车道分配和信号配时参数联合优化,以使路网容量最大;下层模型是用户均衡分配模型,可预测司机对于某种路网车道分配和信号设置的择路行为.用基于灵敏度的启发式算法进行了算例分析.结果表明,该模型可以合理调节路网路径的阻抗,使交通量的分布更均衡,路网备用容量比现有模型增大了32%. |
| 关 键 词： | 可变车道 备用容量 信号配时 用户均衡 双层模型 |

| Abstract: | To study the influence of lane allocation on road network capacity,a bi-level programming model of network reserve capacity was established by allocating lane numbers in both directions of two-way roads and setting traffic signal-timing parameters at individual intersections.The upper-level problem is the integrated optimization of lane allocating and signal timing to maximize the reserve capacity of road network.The lower-level problem represents a network equilibrium model,which predicts the reaction(i.e.... |
