摘要
为缓解道路拥堵,提出了1种基于含两车道的双通道单出口路网模型的反馈策略——畅通指数反馈策略,通过与3种传统信息反馈策略对该路网模型交通流特性参数影响的对比,探究了畅通指数反馈策略的优越性。仿真结果表明,与前3种传统信息反馈策略相比,畅通指数反馈策略下,道路上车辆平均速度、车辆数及交通流量随时间变化较为稳定,道路通行能力得到更好地提高。
To alleviate road congestion,a smooth index feedback strategy of dual channel with two lanes of the road network model was proposed,which was based on a single export.With 3 kinds of traditional information feedback strategies on the comparison of road network model of traffic flow characteristic parameters influence,the superiority of the strategy index smooth feedback was explored.The simulation results showed that compared with the first three traditional information feedback strategies,under the smooth index feedback strategy,the average speed of vehicles,the number of vehicles and the traffic volume change steadily with time,and the road capacity were improved.
