论文摘要
我们引入了一种实时自适应交通信号控制的启发式调度算法，以减少交通拥堵。该算法采用了基于车道的模型，该模型估算了通过不同车道接近交叉路口的所有车辆的到达时间，然后计算一个时间表（即信号正时计划），从而最大程度地减少所有接近车辆所产生的累积延迟。描述了状态空间，修剪检查和可允许的启发式启发式，并显示能够实时生成相交时间表（即每秒）。由于启发式方法的有效性，在模拟的测试环境和实际现场测试中，所提出的方法的表现优于不太表现力的动态编程方法和以前的运行时性能方法。
We introduce a heuristic scheduling algorithm for real-time adaptive traffic signal control to reduce traffic congestion. This algorithm adopts a lane-based model that estimates the arrival time of all vehicles approaching an intersection through different lanes, and then computes a schedule (i.e., a signal timing plan) that minimizes the cumulative delay incurred by all approaching vehicles. State space, pruning checks and an admissible heuristic for A* search are described and shown to be capable of generating an intersection schedule in real-time (i.e., every second). Due to the effectiveness of the heuristics, the proposed approach outperforms a less expressive Dynamic Programming approach and previous A*-based approaches in run-time performance, both in simulated test environments and actual field tests.
