    • A method includes determining candidate schedules for plural vehicles traveling in a transportation network comprising and identifying a gridlock area in the transportation network by simulating travel of the vehicles according to the candidate schedules. The gridlock area includes a geographic subset of the transportation network during a time window having at least a predetermined number of failed candidate schedules that result in a decrease of a throughput parameter. The throughput parameter represents flow of travel of the vehicles in the transportation network. The method also includes determining an alternate schedule that differs from the candidate schedule for one or more of the plural vehicles (e.g., a first vehicle of the plural vehicles) that is traveling through the gridlock area. The alternate schedule dictates travel of the one or more of the plural vehicles (e.g., the first vehicle) without decreasing the throughput parameter of the transportation network.
    • 一种方法包括确定在运输网络中行驶的多个车辆的候选时间表,其包括根据候选时间表模拟车辆的行驶并识别交通网络中的锁定区域。 在具有导致吞吐量参数的减少的至少预定数量的失败的候选时间表的时间窗口期间,所述网格锁区域包括所述运输网络的地理子集。 吞吐量参数表示运输网络中车辆的行驶流程。 所述方法还包括确定与所述多个车辆(例如,多个车辆中的第一车辆)中的一个或多个的候选时间表不同的替代时间表,所述多个车辆正在行驶通过所述锁定区域。 备选时间表指示多个车辆(例如,第一车辆)中的一个或多个的行驶,而不减少运输网络的吞吐量参数。
