According to the low positioning precision and high cost of traditional vehicle positioning technologies, and combined advantages of the newly arisen visible light communication like no extra transmitter needed, no electromagnetic interference and free license, this paper proposed a vehicle positioning method based on traffic light, which could generate the vehicle's position with the time difference of arrival of the signal light. Also its improved methods based on plan revolution theory were discussed to overcome the deficient in non-coplanar condition and improve the positioning precision. Simulation results showed that these methods, with simple computation and low implementation cost, could realize a real-time high-precision positioning performance, and could meet the requirements of the intelligence transportation system.
