Dynamic traffic information estimation based on floating car data

Abstract

The road traffic information changed by authority frequently which effect the public travel due to they can’t obtain this information timely. Fortunately the floating car data can be used to analyze and estimate such traffic information timely. This work first proposed an advanced map matching method combined both local and global road map information. Second we presented an automatic algorithm based on the substance of road intersection to estimate the road traffic control information in real time. We take the floating car data of Fuzhou city to verify the efficient of our method. Experiments result indicates that the traffic information on intersection can be estimated accurately.
