An example method involves identifying one or more potential road segments commonly connecting at least two locations, receiving spatio-temporal weather information predicting future weather conditions along each potential road segment, and for each potential road segment, evaluating a partial cost function that includes a sum of a set of road segment weighted cost factors, where the sum of the set of road segment weighted cost factors is less than the sum of the set of road segment weighted cost factors. The at least one road segment weighted cost factor includes an adverse weather risk factor based on future weather conditions along the potential road segment. The method further involves selecting a set of selected road segments and corresponding road segment target speeds for use when the vehicle travels between the at least two locations to avoid adverse weather conditions based on a minimization of a total cost function that is a sum of partial cost functions associated with a set of road segments commonly connecting the at least two locations.
一种示例方法涉及识别一个或多个共同连接至少两个地点的潜在路段,接收预测每个潜在路段沿途的未来天气状况的时空天气信息,以及对于每个潜在路段,评估部分成本函数,该部分成本函数包括一组路段加权成本因素的总和,其中,至少一个路段加权成本因素包括基于潜在路段沿途的未来天气状况的不良天气风险因素。该方法还涉及基于总成本函数的最小化,选择一组选定的路段和相应的路段目标速度供车辆在至少两个地点之间穿行时使用,以避免不良的天气状况,总成本函数是与共同连接至少两个地点的一组路段相关联的部分成本函数的总和。
