Combined with the consideration of the characteristics of city buses and the research of the latest positioning technologies and algorithms, we present a GPS-Free city bus real-time positioning system. This system contains the Optimized Residual Weighting positioning algorithm (ORwgh) which is robust to non-line-of-sight (NLOS) error in time of arrival (TOA) measurements and the dead-reckoning positioning method. It synthesizes the results of them according to different application environments. We have simulated the system by taking the line of No. 101 bus in Jinan for example. Simulation results show that the system has high accuracy of positioning which can meet the need of the positioning of city buses.
