交通交叉口控制中的运行方式与慢即快效应
Operation Regimes and Slower-is-Faster-Effect in the Control of Traffic Intersections
摘要：
众所周知，城市地区交通流的效率主要取决于信号灯的运行。在这里，信号控制的元素进行了讨论，基于最小化的总行程时间或车辆排队。有趣的是，我们发现了不同的运行方式，其中一些涉及“慢即快效应”，其中延迟切换会减少平均行驶时间。这些运行机制表征了城市道路网络中不同的交通流组织方式。除了优化一个阶段的方法，我们还讨论了优化多个阶段的过程和优点。提升车辆排服务，支持“绿波”自组织，拟考虑新到车辆停靠价格。
英文摘要：
The efficiency of traffic flows in urban areas is known to crucially depend on signal operation. Here, elements of signal control are discussed, based on the minimization of overall travel times or vehicle queues. Interestingly, we find different operation regimes, some of which involve a "slower-is-faster effect", where a delayed switching reduces the average travel times. These operation regimes characterize different ways of organizing traffic flows in urban road networks. Besides the optimize-one-phase approach, we discuss the procedure and advantages of optimizing multiple phases as well. To improve the service of vehicle platoons and support the self-organization of "green waves", it is proposed to consider the price of stopping newly arriving vehicles.
