Using already laid fibre, ideally on both sides of the highway, new levels of traffic flow monitoring, management incident detection and hard shoulder monitoring are all achievable with the whole OptaSense “network” interfacing in real-time to traffic command and control systems.
This single buried sensor will replace all or most of the current roadside point sensors and immediately provides:
Traffic is monitored at 10 metre points in real time along the whole length of the deployed roadside fibre.
The constant data output can be integrated into a client’s existing command and control systems which in turn instructs their various roadside traffic signage as well as providing the infrastructure operators and maintainers with a set of clear Graphical User Interfaces to allow for effective monitoring and decision making.
A client can choose various speed limits that require alerts to be generated.
Average Journey Times
Journey times between selected points and junctions are monitored and reported dynamically.
The sensing system will detect when moving traffic comes to a halt as part of the Traffic flow application above and provide an accurate location of the incident.
In addition, any associated noise created by an incident in close proximity to the fibre, is separately detected and will add to the understanding of the severity of the incident.
Hard Shoulder Monitoring and All Lane Working
With a fibre installed close to or in the hard shoulder the sensing system has the capability to monitor traffic flow as well as stopped traffic.
To compliment incident detection and hard shoulder monitoring, the sensing system will detect personnel walking in close proximity to the fibre.
In addition to Real Time data outputs the Pattern of Life across the infrastructure can be analysed over longer periods of time. This Pattern of Life view will assist an operator in understanding and planning for:
- Busy traffic periods
- New road builds
- Better highway access and egress
- Effective incident response and traffic management
- Provision of evidence to support incident investigation
- Effective positioning of cameras and physical security barriers.
