信息反馈策略对含两车道的双出口路网影响研究

智能交通系统可以实时反馈路况信息以及诱导出行,从而缓解交通拥堵。最早提出的双通道信息反馈策略主要是针对备选路径完全相同的单车道路网模型。针对现有研究的不足,建立了含两车道的双通道双出口路网模型,并通过数值模拟研究了平均速度、车辆数、交通流量以及随机度信息反馈策略对该道路模型中交通流参数的影响。仿真结果表明,平均速度和车辆数反馈策略的引入将降低道路平均流量,相反随机度反馈策略的引入可一定程度的提高道路平均流量,使得路网道路上车辆通行状况更好。故随机度反馈策略用于含两车道的双通道双出口路网较优。

Research on the Influence of Information Feedback Strategy on Double Export Road Network with Two Lanes

Intelligent traffic system can feedback traffic information and induce travel in real time, thus alleviating traffic congestion. The first proposed dual-channel information feedback strategy is mainly for the alternative path is exactly the same bike road network model. In this paper, a dual - channel dual - exit road network model with two lanes is established for the shortcomings of existing research. And the influence of average speed, vehicle number, traffic flow and random degree information feedback strategy on the traffic flow parameters in the road model is studied by numerical simulation. The traffic flow parameters Impact. The simulation results show that the average speed and the number of vehicle feedback strategies will reduce the average traffic of the road. The introduction of the random feedback strategy can improve the average traffic of the road and make the traffic on the road network better. So the randomness feedback strategy is used for two-lane dual-channel dual-exit road network.
