Study and Test for Countermeasures against Interference with Radio Information Transmission of Train Operation Assist Equipment

Abstract

Recently, systems using radio communication for train control or operation assistance have been widespread, and they are contributing to advancement of operations, improvement of safety and others. On the other hand, security of information transmission has become very important. NTSEL carried out a case study using our original equipment for preventing level crossing accidents as a model in order to consider methods of detections and countermeasures against accidental or artificial interference on information transmission. The results of the study were verified by actual train running tests.
