基于预测的城市交通拥堵传播与控制策略研究

Studies on Congestion Propagation and Control Strategies of Urban Transportation Based on Prediction

  • 摘要: 为缓解城市交通拥堵,提高城市交通网络的运行效率,提出了预测型交通拥堵控制策略的理念. 运用改进的中观交通仿真模型模拟城市交通流的运动规律,采用类似随机动态交通分配的方法对动态的OD进行网络加载,得到了交通状态的预测,从而提前判断交通拥堵的发生,制定相应的交通拥堵控制策略,防堵于未然. 仿真结果验证了本文提出的方法可以有效地控制交通拥堵.

     

    Abstract: For eliminating the traffic jams and improving the operating efficiency of urban transport network, a predictive control strategy for traffic congestion was developed. The improved mesoscopic traffic simulation model was presented to simulate propagation of the urban traffic flow, using a method which was similar with stochastic dynamic traffic assignment to establish transportation network OD loaded model in order to acquire the traffic states in advance. Simulation results also validate the proposed method can control traffic jams.
