METHOD AND SYSTEM FOR DETERMINING A DEVIATION IN THE COURSE OF A STRETCH OF A ROAD |
摘要 |
A method and system for identifying a lateral deviation in the course of a road segment is described. Positional data is collected from a plurality of vehicles travelling along a road stretch. A map matching error associated with the position data is used to determine an average map matching error and average absolute map matching error for travel along the road stretch. A lateral deviation in course is identified when the average map matching error measures are both above a given threshold, and where the detected deviation is of a given minimum length. Other indicators of deviation can be considered including a direction of the possible deviation, and impact on travel in the opposite driving direction. Data relating to the determined deviation is generated, including a speed of travel through the deviated region, and used to enhance traffic information. |
