Functional Areas

MCM Environmental Information Collection

• The center shall remotely control environmental sensors that measure road surface temperature, moisture, icing, salinity, and other measures.
• The center shall remotely control environmental sensors that measure weather conditions including temperature, wind, humidity, precipitation, and visibility.
• The center shall assimilate current and forecast road conditions and surface weather information using a combination of weather service provider information (such as the National Weather Service and value-added sector specific meteorological services), data from traffic and traveler information providers, and environmental data collected from sensors deployed on and about the roadway as well as the fleet of maintenance and construction vehicles and the broader population of vehicle probes.
• The center shall provide weather and road condition information to weather service providers and center personnel.
• The center shall respond to control data from center personnel regarding environmental sensor control and weather data collection and processing.
• The center shall collect operational status for the roadside and vehicle-based environmental sensor equipment.

Roadway Environmental Monitoring

• The field element shall include surface and sub-surface environmental sensors that measure road surface temperature, moisture, icing, salinity, and other measures.
• The field element shall include environmental sensors that measure weather conditions including temperature, wind, humidity, precipitation, and visibility.
• The field element's environmental sensors shall be remotely controlled by a maintenance center.
• The field element's environmental sensors shall be remotely controlled by a traffic management center.
• The field element's environmental sensors shall be remotely controlled by weather service providers such as the National Weather Service or value-added sector specific meteorological services.
• The field element shall provide environmental sensor equipment operational status to the controlling center or maintenance vehicle.
• The field element shall provide environmental sensor equipment fault indication to the controlling center or maintenance vehicle.
