摘要

A large number of traffic safety and traffic efficiency problems can be solved by technology of V2X(Vehicle to X, X can be infrastructure, vehicle, pedestrian and so on). While map matching technology is the foundation of many V2X applications. This article focuses on V2I(Vehicle to Infrastructure) technology, one of the V2X technology. And it proposes a map matching algorithm based on technology of V2I. Nearby vehicles make information interaction by OBU(on board unit). OBU also obtains local logic map data by V2I. Candidate link set is established by local logic map data. And then the matching link can be determined by calculating the candidate link weight. At last, the real vehicle test was implemented in intelligent connected vehicle closed test area in Chongqing. The feasibility of the algorithm was verified by the test.
