| 中文摘要 |
| 针对路网车流分布不均衡的问题, 本文提出基于一致性思想的路网边界流量控制策略. 首先, 基于车辆守恒宏观模型, 描述了区域边界车流的动态演化; 以区域内路段占有率一致作为控制目标, 边界交叉口配时参数为控制输入, 进行区域边界反馈控制设计, 并推导出边界车流输入与内部路段放行比例的解析关系; 最后, 通过路网实测数据验证了边界控制策略的适用性. 结果表明: 边界控制策略不仅能够有效改善路网交通流分布不均衡的状况, 还能够有效降低路网的平均延误、排队长度等指标, 提高路网运行效率. |
| 英文摘要 |
| In view of the unbalanced distribution of traffic flows in urban traffic networks, this paper proposes a perimeter control strategy of road networks based on consistency thought. Firstly, the evolution of traffic flows in regional boundary links is modeled by vehicle conservation equation, and the perimeter feedback control approach is proposed with the occupancy consistency of the links in network as control objective, and the signal timing of boundary intersections as control input. And then the analytical relationship between the traffic flow input of boundary links and the discharging proportion of internal links is deduced. Finally, chose the measured data of the road network to verify the applicability of the perimeter control strategy, which shows that the perimeter control strategy can not only effectively improve the unbalanced distribution of traffic flow in the road network, but also reduce the average delay, queue length and other indicators and improve the operation efficiency of the network. |
