Recently, the traffic congestion in modern cities has become a growing worry
for the residents. As presented in Baidu traffic report, the commuting stress
index has reached surprising 1.973 in Beijing during rush hours, which results
in longer trip time and increased vehicular queueing
在实时自适应交通信号控制方面,提出了一种启发式调度算法,该算法采用了基于车道的模型,通过估算通过不同车道接近交叉口的所有车辆的到达时间,计算出最小化所有接近车辆产生的累积延迟的时间表,并应用状态空间、局部修剪和 A * 搜索等技术实现了实时调控,并且在模拟测试环境和实际现场测试中,由于启发式的有效性,该方法的运行性能优于较少表达的动态规划方法和以前基于 A * 的方法。
