摘要
针对路径诱导方案在城市交通拥堵控制方面的不足,在传统A？算法中引入了实时的动态权值,提出了带动态权值的DA？算法。通过实验证明,DA？算法在道路拥堵严重的情况下,能节省20%~46%的车辆行驶时间。该算法具有预防拥堵、增加道路利用率等理论价值和实际意义。
In order to solve the problem of traffic congestion in the city, the A？ algorithm for traditional route guidance scheme in congestion control was modified while real time dynamic weight was introduced. A DA？ algorithm with dynamic weights was proposed. Experiments proved that the DA？ algorithm can effectively save the 20% -46% vehicle travel time in road congestion in severe cases. It can prevent from congestion and therefore increase the utilization of roads.
