信号交叉口对城市交通效率和车辆燃油经济性起着重要作用。提出了一种互联自动驾驶车辆的交通信号控制和车速优化协同方法，该方法同时优化交通信号配时和车速轨迹。该方法包括两个层次，即，路侧交通信号优化和车载车速控制。前者计算最优交通信号配时和车辆到达时间，以最小化所有车辆的总行程时间;后者优化发动机功率和制动力，以最小化单个车辆的燃油消耗。分别将枚举法和伪谱法应用于路侧和车载优化。仿真研究进行了比较所提出的方法与基准方法。结果表明，采用协同方法可以显著提高运输效率和燃油经济性。
Signalized intersections play an important role in transportation efficiency and vehicle fuel economy in urban areas. This paper proposes a cooperative method of traffic signal control and vehicle speed optimization for connected automated vehicles, which optimizes the traffic signal timing and vehicles’ speed trajectories at the same time. The method consists of two levels, i.e., roadside traffic signal optimization and onboard vehicle speed control. The former calculates the optimal traffic signal timing and vehicles’ arrival time to minimize the total travel time of all vehicles; the latter optimizes the engine power and brake force to minimize the fuel consumption of individual vehicles. The enumeration method and the pseudospectral method are applied in roadside and onboard optimization, respectively. Simulation studies are conducted to compare the proposed method with benchmark methods. The results show significant improvement of transportation efficiency and fuel economy by the cooperation method.
