1 5 RTRI report Vol. 24, No. 3, Mar. 2010 JR ATS-Dx Development of ATS-Dx with Permissible Speed Profile Using an On-board DatabaseHiroyuki FUJITA Hideki ARAI Kazutoshi SATOM asaaki KADOWAKI Michiya SADAKARI The authors had developed the basic train control system of ATS (Automatic Train Stop) -X which is interoperablewith the existing ATS-Sx system already introduced into almost all the conventional lines of JR companies. Thesafety level of ATS-X system is higher than that of ATS-Sx system because ATS-X system has function to com-pare train speed with a permissible speed profile calculated by on-board device. This time, the authors developeda new ATS system called ATS-Dx system which uses a database installed in the on-board device, and is based onthe ATS-X system.
2 The ATS-Dx system is able to reduce the construction costs and the number of beacons withrespect to the function of limited speed reference for curves and turnouts. In this paper, the authors report on thespecifications of this system and the functional field test results.
