闭环交通控制系统可以通过一天的时间（TOD）模式或交通响应计划选择（TRPS）模式操作。当正确配置时，TRPS模式具有提供最佳操作的潜力，因为其能够适应异常交通状况，例如事故、特殊事件和假日交通。TRPS模式还可以减少对信号配时计划进行频繁重新设计/更新的需要。到目前为止，还没有任何正式的准则来选择稳健和最佳的TRPS系统参数和阈值。因此，交通工程师通常恢复到TOD操作模式，以便于设置。本报告提供了一种新的方法，用于可靠和最佳地选择TRPS参数和阈值。该报告提出了TRPS系统设置的创新框架，采用了综合方法，结合了多目标进化算法和监督判别分析。为便于执行，已制定的准则以简化表格形式列出。使用硬件在环仿真验证了准则。与优化过程中遇到的最糟糕的解决方案相比，最终解决方案同时节省了53%的延迟和19%的停止。
Closed-loop traffic control systems can be operated by either Time-of-Day (TOD) mode or Traffic Responsive Plan Selection (TRPS) mode. When properly configured, the TRPS mode has the potential to provide an optimal operation due to its ability to accommodate abnormal traffic conditions such as incidents, special events, and holiday traffic. TRPS mode can also reduce the need for frequent redesign/updates to signal timing plans. To date, there have not been any formal guidelines for selection of robust and optimal TRPS system parameters and thresholds. Consequently, traffic engineers usually revert to the TOD mode of operation for its ease of setup. This report provides a new methodology for robust and optimal selection of TRPS parameters and thresholds. The report presents an innovative framework of TRPS system setup following a comprehensive approach that incorporates a multi-objective evolutionary algorithm and a supervised discriminant analysis. The developed guidelines are presented in simplified tables to facilitate their implementation. Guidelines were verified by using hardware-in-the-loop simulations. Compared to just the worst possible solutions encountered during the optimization, the final solution provided a concurrent savings of 53% in delay and 19% in stops.
