Document Type and Number:
WIPO Patent Application WO/2020/243979
Kind Code:
A1
Abstract:
Systems and methods for providing a reliability of passing time for a path in route planning．The methods may include obtaining a route planning request from a user terminal(510)；determining a plurality of candidate paths(520)；determining a first estimated travel time cost and a first variance for each link of a target candidate path(530)；determining a second estimated travel time cost for the target candidate path based on the first estimated travel time cost of each link；determining a second variance for the target candidate path based on the first variance associated with each link of the target candidate path(540); determining a reliability of passing time for the target candidate path based on the second estimated travel time cost and the second variance(550)；and directing the user terminal to display the target candidate path with the reliability of passing time(560)．
