SEGMENT DEFINING METHOD, TRAVEL TIME CALCULATION DEVICE, AND DRIVING SUPPORT DEVICE |
摘要 |
A section defining method separates a road between a departure point and a destination point into a plurality of links under a predetermined condition and defines a section based on a link cost, which is an index indicating ease of travel and set for each link. The section is used to generate guide information provided to a driver of a vehicle. The section is defined by combining, among the plurality of links between the departure point and the destination point, at least two continuous links that yield a decrease in standard deviation, which is based on sums of the link costs. |
