| 中文摘要 |
| 为了提高高密度路网地区的交通管理水平, 针对高密度路网特点, 提出了一种分布式信号控制模型, 用于控制交叉口的排队管理. 该模型建立了多目标函数, 包括了平均出行延误最小和平均排队占比最小; 模型约束包括了排队长度估计、信号控制参数约束. 此外, 为了避免排队回流现象的产生, 还建立了具有高优先级的排队回流约束. 仿真结果表明, 该模型提高了高密度路网地区的交通通行效率, 并有效避免交叉口排队回流现象. |
| 英文摘要 |
| To improve the traffic management in a high-density network, we propose a distributed traffic signal control model to manage the queues in the intersections, based on the characteristics of high-density network. This model minimizes the average travel delay and the average queue ratio under the constraints on the queue dissipation and the signal control parameters. In addition, to avoid queue spillbacks, a high-priority queue spillback constraint is built. Simulation results illustrate the improvement of the traffic travel efficiency in high-density networks, and the effective avoidance of queue spillbacks. |
