What is it?
- Weather Detection Systems include sensors that
measure atmospheric water vapor, pavement temperature, fog density,
and ice and snow levels.
- These sensors are often integrated with other
technologies that can forecast weather, disseminate traveler information,
maintain roads, and control traffic in adverse weather. See our
Telecommunications Diagrams on Weather
Detection for more information.
Key Results
- Sensors for different types of weather are successful
at detecting and transmitting weather information.
- Highway personnel use weather sensor information
to make decisions about road maintenance.
- Drivers use weather sensor information in order
to practice safe driving (i.e. decreasing speeds on icy roads).
Benefits
- Weather-related road accidents are reduced when
weather conditions are detected and road users are prepared for
potential road hazards.
- Highway personnel can respond efficiently to
adverse road weather conditions when they are fully informed of
current weather conditions.
Costs
- RWIS: Capital Cost: 25k, Operation and Maintenance:
0.4-2.5k per year
- ESS: Capital Cost: 10-50k, Operation and Maintenance:
1.9-4.1k per year
- VMS: Capital Cost: 10-50k, Operation and Maintenance:
1.9-4.1k per year
- HAR: Capital Cost: 16-32k, Operation and Maintenance:
0.6-1k per year
Implementation and Operational Challenges
- Poor communication lines can hinder coordination
of weather detection and traveler information dissemination technologies.
Where are Weather Detection Systems Implemented?
- Weather Detection Systems are implemented across
the United States.
