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 mod-el was proposed ,which was based on a single export .With 3 kinds of traditional information feedback strategies on the compari-son of road network model of traffic flow characteristic parameters influence ,the superiority of the strategy index smooth feed-back 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 .
