Systems and methods for determining an estimated time of arrival (ETA) for a service request are provided. The method comprises obtaining a service request comprising a start point and an end point (510); determining a preset path from the starting point to the ending point (520); for each of the at least two preset road segments, determining a corresponding vector representing a topological relationship between the at least two preset road segments (530); an ETA of the service request is determined using a machine learning model based on the vectors corresponding to the at least two preset segments (540).
本申请提供了确定服务请求的预估到达时间(ETA)的系统和方法。所述方法包括获取包括起点和终点的服务请求(510);确定从起点到终点的预设路径(520);对于至少两个预设路段中的每一个预设路段,确定表示至少两个预设路段之间拓扑关系的对应向量(530);使用机器学习模型,基于对应于至少两个预设路段的向量,确定服务请求的ETA(540)。
