2005 – Oct – Lee & Tay – Tetra for Driverless Rapid Transit System

Edwin Lee Senior Systems Engineer (Communications) Lim Hock Tay Assistant Manager (Communications) Land Transport Authority This paper identifies the attributes of a radio communication system that are essential for the operation of a driverless rapid transit system, and discusses how these requirements may be fulfilled using a TErrestrial Trunked RAdio (TETRA) system. The design of the TETRA system in the Singapore Circle Line, a project that is currently under construction, is also briefly introduced. Some useful experiences that have been gained from the implementation of TETRA for the Singapore North East Line project, and how these are addressed in the CCL radio system design are also discussed.
