Under certain conditions giving priority to trucks at signalized intersections will benefit all vehicles because of elimination of extra delays associated with stop and go trucks due to their size and slow deceleration and acceleration rates. In this paper, we develop, analyse and evaluate a traffic light control system for signalized intersections that takes into account the differences in dynamics and characteristics between trucks and passenger vehicles. The proposed traffic light control system combines simulation-based optimization techniques timing the baseline traffic signals and model-based active strategy giving priority to trucks when it is to the benefit of all vehicles involved. In order to overcome the computational constraints of the simulation-based approach, a multiple agent-based solution utilizing multiple simulators has been proposed for large scale road network applications. The evaluation results show consistent improvements in reducing the truck traffic delays (5% to 10%) and the number of truck stops without delaying passenger vehicles whose travel time and number of stops have also been reduced. The reductions of vehicle delays and number of stops lead to reduction in emission levels and fuel consumption for both trucks and passenger vehicles.

卡车优先交通信号灯控制的联合仿真,优化控制方法

在某些情况下,在信号交叉口优先使用卡车将使所有车辆受益,因为消除了因停放卡车的尺寸,缓慢的减速和加速率而引起的停驶卡车的额外延误。在本文中,我们开发,分析和评估了信号交叉口的交通信号灯控制系统,该系统考虑了卡车和乘用车之间的动力学和特性差异。拟议的交通信号灯控制系统结合了基于仿真的优化技术,对基线交通信号进行计时以及基于模型的主动策略,以便在涉及所有车辆的情况下优先考虑卡车。为了克服基于仿真的方法的计算限制,已经提出了用于大型道路网络应用的,使用多个模拟器的基于多代理的解决方案。评估结果表明,在减少卡车交通延误(5%到10%)和卡车停靠点数量的同时,不延迟旅行时间和停靠点数量有所减少的乘用车方面,一直都有改进。车辆延误和停车次数的减少导致卡车和客运车辆的排放水平和燃油消耗的减少。
