Research for Practical Use of Smartway and Deployment of ITS Spot Services

The Ministry of Land, Infrastructure, Transport and Tourism (MLIT) has been conducting research and development (R&D) of “Smartways,” which allow various information to be exchanged between vehicles, drivers, pedestrians, and other users. Based on past R&D, intelligent transportation system (ITS) spots (DSRC antennas) have been installed at more than 1,600 locations nationwide by the end of March 2011 and IT spot services will commence throughout Japan. This paper outlines the MLIT’s R&D on Smartways, shows some examples of ITS Spot services deployed as road-vehicle cooperative systems in large scale, and reports on ongoing R&D on interactive information services.
