Abstract:

According to the characteristics of handover location technique in cellular wireless communication network, a map matching algorithm for inner suburban freeway has been developed. Based on a complete navigation digital map and reliable handover location database, a map matching belief function was developed according to Bayesian decision theory choosing the frequency of handover happening in a candidate link and the probability of route choice between two adjacent handover positions, and results of the map matching belief function and the connectivity criterion were combined together for solving the map matching of the flow of handovers. Field data collected from the surveyed tests were used to calibrate feasibility and validity of the proposed map matching algorithm.
