摘　　要：To alleviate the resulting increase in energy consumption and emissions and other issues caused by the traffic congestion ahead of the expressway toll station, a novel traffic flowcontrol method is put forward based on the environment-friendly conception. The technical thinking of inducing the slowly moving traffic into a batch pass is determined based on the conclusion of the research, traffic flowtheory and traffic sensing detection technology. The model of stop times is established and the parameters of the system are optimized in accordance with the principle of minimizing the fuel consumption. The optimal location selection of traffic control lights and Detector 2 for queue of different lengths at toll stations are calculated based on the model. Finally, the effect of the congestion flowcontrol system is verified via the Paramics simulation system. The result shows that the control system is capable of reducing90% of fuel consumption for vehicles going through toll stations.以缓解因高速公路收费站站前路段拥挤车流并由此带来的能源消耗加剧与排放物激增等问题,基于环境友好理念,提出了一种新型控制办法.首先,基于调查结论、交通流理论和车辆感应技术,确定了将缓慢行进车流向分段放行车流引导的技术路线.建立了停车次数模型,以燃料消耗最小化为目标,对模型中的参数进行了优化,并对收费站前车辆不同排队长度情境下的交通控制信号灯、检测器2的最佳布局位置进行了计算.最终,通过Paramics仿真软件对此拥挤车流控制技术的效果进行了验证.结果显示,此控制系统可以有效减少收费站通行车辆90%的燃料消耗.
