Method of detecting transportation network database errors and devices thereof

摘要

A method of detecting errors in road characteristics in a transportation network database includes collecting sequential location measurements from probes traversing between two end points, fitting trace segments having a curved or linear shape between the sequential location measurements collected from the probes to form a probe trace, comparing a position of the probe traces with a position of a calculated path between the two end points, where the calculated path is formed from linked transportation network segments each of the linked transportation segments having a curved or linear shape, where the calculated path follows the road characteristics defined by the attributes associated with the linked transportation segments, and identifying a potential error in the attributes if a probe trace deviating in position from the calculated path is greater than a deviation threshold.

1. A method of detecting errors in road characteristics defined by one or more attributes associated with a transportation network database, comprising:
in a server computer, performing operations for:
collecting a plurality of sequential location measurements from each of a plurality of probes traversing between two end points;fitting trace segments having at least one of a curved and linear shape between the plurality of sequential location measurements collected from each of the plurality of probes to form a probe trace for each of the of the plurality of probes;comparing a position of at least one of the plurality of probe traces with a position of a calculated path between the two end points, where the calculated path is formed from a plurality of linked transportation network segments, each of the linked transportation segments having at least one of a curved or linear shape, where the calculated path follows the road characteristics defined by the one or more attributes associated with the one or more of the linked transportation segments; andidentifying a potential error in the one or more attributes if a number of the plurality of probe traces deviating in position from the calculated path is greater than a deviation threshold.
