该研究评估的多模式智能交通信号系统（MMITSS）的基础上，利用从MMITSS原型和仿真分析收集的数据进行现场数据分析的潜在网络范围的影响。对智能交通信号系统（I-SIG）、公交信号优先（TSP）、货运信号优先（FSP）以及TSP和FSP的组合应用进行了评价。MMITSS旨在通过使用先进的通信和数据的信号走廊来提高机动性，以促进客运车辆，行人，过境，货运和紧急车辆通过该系统的有效旅行。现场数据分析表明，MMITSS应用有效地改善了装备车辆的行程时间和延误。特别是，与基本情况相比，FSP将联网卡车的延迟减少了20%，I-SIG将行程时间可靠性提高了56%。模拟研究发现，I-SIG实现了车辆延误减少高达35%，TSP有效地节省了运输和客运车辆在TSP运行的走廊上的旅行时间，但偶尔会增加系统范围内的延误，由于减少绿色时间的小街。FSP仿真结果表明，FSP成功地减少了连接的卡车的旅行时间，但也增加了系统范围内的延误，由于增加了侧街的延误。模拟研究发现，TSP和FSP应用程序的组合是有效的分配优先级的卡车的基础上预定义的层次结构的控制。该研究得出结论，MMITSS I-SIG、TSP、FSP以及TSP和FSP应用的组合改善了测试设施上配备的乘汽车、卡车和运输车辆的车辆行驶时间、延误和行驶时间可靠性，但代价是它可能产生整个系统范围的负面影响。
The study evaluates the potential network-wide impacts of the Multi-Modal Intelligent Transportation Signal System (MMITSS) based on a field data analysis utilizing data collected from a MMITSS prototype and a simulation analysis. The Intelligent Traffic Signal System (I-SIG), Transit Signal Priority (TSP), Freight Signal Priority (FSP), and the combination of TSP and FSP applications were evaluated. MMITSS seeks to improve mobility through signalized corridors using advanced communications and data to facilitate the efficient travel of passenger vehicles, pedestrians, transit, freight, and emergency vehicles through the system. The field data analysis demonstrated that MMITSS applications effectively improved the travel time and the delay of the equipped vehicles. In particular, FSP reduced the delay of connected trucks by up to 20% and I-SIG improved travel time reliability by up to 56%, compared to the base case. The simulation study found that I-SIG achieved vehicle delay reductions up to 35% and TSP effectively saved travel time for both transit and passenger vehicles on the corridor where TSP was operated; but occasionally increased the system-wide delay, due to reduced green times on the side streets. FSP simulation results indicated that FSP successfully reduced travel times for connected trucks, but also increased system-wide delay, due to increased delays on side streets. The simulation study found that the combination of TSP and FSP applications was effective in assigning priority to trucks based on a pre-defined hierarchy of control. The study concludes that the MMITSS I-SIG, TSP, FSP, and the combination of TSP and FSP applications improve vehicle travel time, delay, and travel time reliability for equipped passenger cars, trucks, and transit vehicles on the test facility, but the tradeoff is that it may produce overall system-wide negative impacts.
