Abstract

ATO (Automatic Train Operation) systems which are equipment for automated driving control under protection of ATC (Automatic Train Control), continuous type of ATP, is introduced in specific types of line, such as AGT (Automated Guideway Transit ) systems or subway systems in Japan. There is a growing need for new type ATO system which is operated by a staff who is not required driver's license in order to reduce operating costs further. We have developed an ATO system based on ATS (Automatic Train Stop) -DK which is intermittent type ATP and equipped continuous speed check. In this paper, we show the concept of the ATS-based ATO system and report on the specifications of this system and functional field test results.

Article
The authors developed a new ATP (Automatic Train Protection) system in Japan: the ATS (Automatic Train Stop) system. The new system called ATS-Dx is based on the ATS-X system which is interoperable with the existing ATS-S system already deployed on almost all JR company conventional lines. ATS-Dx guarantees an even higher level of safety than the ATS-S system because it includes a function to compare actual vehicle speed with a permissible speed profile calculated by an on-board equipment. The ATS-Dx system can also reduce construction costs and the number of beacons usually required for providing reference speed limits in curves and for turnouts by virtue of an on-board database. In this paper, the authors describe the system's specifications and the results from field trials to test this function.
