Problem Description
Unexpected sharp curves can be a safety hazard for speeding or inattentive motorists. Safety engineers know these road segments need special treatment because of higher accident rates.
Of particular concern are trucks approaching sharp curves, exit ramps or other hazardous road segments. Judging a safe approach speed may be difficult for drivers unfamiliar with the road. As a result, speeds may be excessive and truck roll-over is possible.
Solution
The Canoga Traffic Monitoring Card in combination with 701 Microloops, 702 Non-invasive Microloops or inductive loops can detect a critical traffic event and provide an output for the activation of a system that can alert drivers.
A critical traffic event can be a combination of a vehicle exceeding:
- safe speed criteria (a speeding vehicle)
- specified length criteria (for example, a truck)
- safe speed and the specified length criteria (a speeding truck)
When a critical traffic event is detected, the traffic monitoring card:
- generates an output pulse with a user-defined duration
- logs the event condition and occurrence in the event history log
The output pulse can be used to activate different driver alert systems such as flashers or variable message signs.
