A Compute Method of Road Travel Speed based on Mobile Phone Handover Location

Abstract

It is a focus to obtain traffic information from mobile phone location data in recent years. Based on mobile phone handover location technology, and considering the characteristics of the handover location data and drawbacks of the existing map matching algorithms, a new algorithm of road matching based on Fuzzy Logic is proposed. The general principle of this method is to firstly find out the candidate roads considering the constraint of handover cells, and then use fuzzy logical and other constraints to narrow the range of candidate road, and finally obtained the optimal road by the judgment of membership function. At the last of this paper, real mobile phone handover location data, road network data and the base station data of Kunming, the capital city of Yunnan province of China, are used to test the performance of the algorithm, and the travel speed of an experiment road is calculated and the result is satisfactory.
