Liu Ru-cheng · Computer Engineering and Applications Journal · 2007
To overcome the lack in data of current location and utilizes effectively historical information,a Frechet distance measure is introduced for defining a distance between two curves on the basis of analyzing some previous map-matching algorithm and distance measures.And a cloud controller was designed to perform the uncertain cloud reasoning for map-matching algorithm,which have a higher degree of uncertainty related with the map-matched locations.Then,the credibility P is derived as an estimate index of map-matching.This algorithm could provide a warning to user and a means of fast recovery from failure.The results of the experiments demonstrated that the total matching preciseness of the proposed algorithm is better than that of the current position matching.
