There is a growing demand to optimise road networks and to address the freight task, safety issues and traffic congestion. 

Traffic sensors are installed at intervals of 500m and connected in real time to a freeway management system. 

TIRTL is a traffic sensor that provides high reliability operation (>99.95% availability) with virtually no maintenance and the lowest life-time sensor costs (>25 years). 

TIRTL is integrated into CMCS (Serco) in NSW, Australia, and into STREAMS (Transmax) in South Australia.
