    • The disclosed approaches for processing traffic signal priority requests include receiving traffic signal priority requests from a vehicle. The number of stopped vehicles at the intersection and on an approach to the intersection is determined in response to receiving each priority request. An activation threshold is computed as a function of an estimated-time-of-arrival (ETA) threshold and the number of stopped vehicles. A vehicle ETA of the vehicle at the intersection is determined in response to each priority request. In response to the vehicle ETA being less than the activation threshold, the priority request is submitted for preemption service processing at the intersection. In response to the vehicle ETA being greater than the activation threshold, submission of the priority request is bypassed for preemption service processing at the intersection.
    • 所公开的处理业务信号优先级请求的方法包括从车辆接收业务信号优先级请求。 响应于接收到每个优先级请求,确定交叉路口处的停止的车辆数量和交叉路口的接近程度。 作为估计的到达时间(ETA)阈值和停止的车辆的数量的函数计算激活阈值。 响应于每个优先权请求确定车辆在交叉点处的车辆ETA。 响应于车辆ETA小于激活阈值,优先级请求被提交用于交叉路口处的抢占服务处理。 响应于车辆ETA大于激活阈值,绕过优先级请求的提交用于交叉路口处的抢占服务处理。

    • Approaches for managing transit signal priority (TSP) requests are disclosed. The arrival of a first transit vehicle at a transit stop is detected, and a first value indicative of an actual arrival time is stored in a memory in response to the arrival of the first transit vehicle at the transit stop. A processor determines from the first value whether or not the actual arrival time of the first transit vehicle satisfies a scheduling parameter. In response to the actual arrival time of the first transit vehicle not satisfying the scheduling parameter, a priority request device is enabled to make TSP requests. In response to the actual arrival time of the first transit vehicle satisfying the scheduling parameter, the priority request device is disabled from making TSP requests.
    • 披露了管理过境信号优先级(TSP)请求的方法。 检测到第一过境车辆在过境站处的到达,并且响应于第一过境车辆在过境站处的到达而将表示实际到达时间的第一值存储在存储器中。 处理器根据第一值确定第一转接车辆的实际到达时间是否满足调度参数。 响应于不符合调度参数的第一中转车的实际到达时间,优先请求装置能够进行TSP请求。 响应于满足调度参数的第一中转车的实际到达时间,禁止优先请求装置进行TSP请求。
