Recently several systems have been proposed as the mobile mapping system. However it is thought that the inspection of measurement accuracy is not sufficient. In this research, the experiments on the measurement of road associated facilities were executed by LANDMark system which is one of the mobile mapping system varying the running speed and the range to the object. As the results, it was proved that the system has the capability to measure the road associated facilities within 4m from the vehicle at the speed of 40km/h.
