Title:
METHOD AND SYSTEM FOR MATCHING TRAJECTORY DATA WITH ROAD NETWORK
Document Type and Number:
WIPO Patent Application WO/2023/068430
Kind Code:
A1
Abstract:
A road network matching system of the present invention comprises: an input unit for receiving trajectory data; a matching server for deriving matching candidate links, which can be matched to the input trajectory data by using a grid index, and matching location data and any one of the matching candidate links while sequentially transitioning the state of the location data included in the trajectory data; an output unit for outputting a set of links matched to the location data included in the trajectory data; and a database for storing a link currently matched, by the matching server, to the location data.
