入口匝道控制是缓解高速公路交通拥堵的有效手段。本研究提出了一种基于区域高速公路OD数据的交通控制方法,以缓解高速公路瓶颈处的交通超载。我们首先定位了高速公路瓶颈的主要司机来源,并确定了实施交通控制方案的匝道。其次,采用差分进化算法计算各交通控制匝道的最优控制时间。结果表明,造成高速公路交通瓶颈的主要驾驶员来源是有限的。通过自适应控制车辆在主要驾驶员源匝道上的等待时间,可以有效缓解高速公路瓶颈处的交通拥堵。
On-ramp control is an effective way to mitigate traffic congestion in freeways. In this study, a traffic control approach is developed based on the OD data of a regional freeway to alleviate the traffic overload in freeway bottlenecks. We first locate the major driver sources of the freeway bottlenecks and identify the on-ramps for implementing the traffic control schemes. Next, the differential evolution algorithm is employed to calculate the optimal control time at each traffic control on-ramp. The results indicate that the major driver sources of the freeway bottlenecks are limited. Traffic congestion in the freeway bottlenecks can be effectively mitigated by adaptively controlling the waiting time of vehicles at the on-ramps of their major driver sources.
