The purpose of the Advanced Group Rapid Transit (AGRT) program was to develop an advanced automated guideway transit system capable of providing high passenger volumes, short waiting times, and high levels of passenger service. The transportation system developed consists of small, automated vehicles which operate on a single lane guideway at short headways with unmanned, off-line stations. The report summarizes the design and development of the Guideway Communication Unit (GCU) for the AGRT program. The GCU is a subsystem of the AGRT command and control subsystem. It functions as an interface between the vehicle command and control subsystem and the test track command and control subsystem. It contains an inductive communication link, a vehicle presence detection system, and magnetic guideway markers. The inductive communication link provides a two-way command and control data path between the wayside and vehicles. This link also provides a failsafe speed limit to the vehicle. The design utilizes eight bit microcomputers and incorporates unique self-exercised software to detect potentially unsafe latent failures within the hardware.
