OptaSense and VicRoads Monash Freeway Project 2015
The Monash Freeway project utilizes Optasense's Distributed Acoustic Sensing (DAS) technology to provide real-time traffic monitoring over 40 km using existing fibre optic infrastructure. The system enables various functionalities such as incident detection, speed estimation, and congestion monitoring, all while minimizing installation requirements and costs compared to traditional methods. This innovative approach offers enhanced situational awareness and safer traffic management without the need for extensive physical infrastructure.
