Integrated road weather systems for effective driver messaging
Challange
Drivers may not be aware of the road conditions that are ahead and drive at inappropriate speeds for the conditions. It can be difficult to notify drivers with timely information at the correct location and time
Solution
Use RWIS to turn weather and road data into meaningful insights. Integrate the RWIS meteorological data to trigger the signs to alert drivers via navigation app or signage about notable hazards.
Benefits
By advancing a system to enable driver messaging, information is spread widely to the public in a timely manner. Thus, increasing driver awareness and preventing accidents due to inclement weather.
Our team of experienced project engineers and skilled technicians is there to explore individual solutions for your road weather monitoring challenge. Advanced RWIS for Driver Messaging The North Dakota Department of Transportation (DOT) in partnership with OTT HydroMet and Haas developed a complete solution for effective messaging in a notoriously difficult weather corridor. The solution integrates several sensors to capture the road conditions with intuitive software platforms to feed the data into a navigation app for immediate notification.
- Trusted suite of road weather instruments from the OTT HydroMet product brand Lufft
- Easy integration to activate signage with the help of flexible software solutions
- Successful collaboration to deliver a customized solution that can be redeployed to other areas
