optasense and vicroads monash freeway project 2015
TRANSCRIPT
Distributed Acoustic Sensing (DAS)
The fibre is the sensor - Real-time situational awareness via light
Achieved via the utilization of existing VicRoads fibre optic assets - OptaSense© provides a real time, linear sensing capability to better and more safely manage traffic conditions.

• Speed Estimation
• Incident Detection
• Congestion Monitoring
• Journey Times
• Vehicle Counting
• Bridge and Tunnel monitoring
• Low flow monitoring
• Fibre Break
• Personnel Intrusion Detection
• Rock Fall
• Seismic activity
Connected to a single dedicated core on the VicRoads Fibre Optic network, OptaSense is deployed in less than a week to monitoring 40 km of the Monash Freeway traffic in real time.

OptaSense Installation
Geo-referencing, Mapping and User Interface
Fibre optic cable is located by a work crew via GPS and matched to the optical distance on the fibre.
Safe to Install and Operate
• No roadside infrastructure
• Minimal installation requirements for work crews on carriageways
• Maintenance activities required on rack mounted equipment only
VicRoads Freeway Condition Thresholds loaded into OptaSense. Settings updated remotely as the system evolves.
