The Cacs Project: How Far Away are We from the Dynamic Route Guidance System?

The CACS project was carried out over 6 years by the Agency of Industrial Science & Technology, MITI, beginning in 1973. In this project, the dynamic route guidance system (DRGS) with considerable scale was experimentally implemented on the road network of Tokyo metropolitan area as the first challenge. Immediately after the project was completed, the Association of Electronic Technology for Automobile Traffic and Driving (JSK: Abbr. of Japanese name) was established by MITI and major private companies in order to follow up on the project.
