Train control system using radio communication - Part 1: General requirement and functional requirement
 N JIS E 3801-1

Annotation

This Japanese Industrial Standard specifies the general requirements and functional requirements of a train control system using radio communication (Japan Radio Train Control system, JRTC) that transmits control information related to safety on railways between the wayside and train using radio communication.

However, this Standard may also be applied to specialized railways such as guiderail system railway.

Functions of the train control system that ensure safe movement of trains or car (hereafter referred to as "trains, etc.") are divided into the following five functions :

a) Ensure safe route to prevent derailment or collision of trains, etc. at crossings, turnouts, or other locations.

b) Ensure safe separation of trains to prevent trains from moving outside safe route and colliding with each other.

c) Ensure safe speeds to prevent derailment of trains due to excessive speed or to keep safe separation of trains.

d) Ensure safe movement of trains passing through level crossings.

e) Ensure safe movement of trains against obstacles on the track, etc.

This Standard applies to a system with automated four functions other than the e). However, it does not apply to automatic train operation with operation staff 1) and automatic train operation without onboard staff.

Furthermore, this Standard also applies to systems that perform automatic operation regarding acceleration, coasting, and deceleration between stations and stopping within constraints of the above functions.
