| 摘 要： | 在出口匝道接地点离交叉口距离过近时, 为避免衔接交叉口的拥堵易回溢至快速路主线, 提出一种基于CTM的出口匝道与衔接交叉口的整合控制模型。在出口匝道存在超长排队时, 实行相位绿灯延长或绿灯提前激活策略; 在出口匝道不存在超长排队时, 以出口匝道及衔接信号控制交叉口车均延误最小化为目标, 实时动态优化衔接交叉口的周期和绿信比。仿真结果表明: 采用控制模型, 衔接交叉口的车均延误虽然增加了1.74s, 但可以将排队长度从大于200m降低至160m以内, 从而可以保证出口匝道衔接区域和快速路主线的畅通, 因此, 控制策略及模型合理有效。

| Abstract: | In order to keep the queues of intersection and off-ramp from backupping to expressway mainline, an integrated control model of off-ramp and correlative intersection was proposed based on cell transmission model(CTM). When overfull queue appeared at off-ramp, red truncation strategy or green extension strategy was adopted. When overfull queue did not appear at off-ramp, the cycle and green signal ratio of intersection were optimized dynamically to minimize the average vehicle delays of off-ramp and correlat... |
