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 collect operational status for the roadside and vehicle-based environmental sensor equipment.
• The center shall collect fault data for the roadside and vehicle-based environmental sensor equipment for repair.

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 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.
• The field element shall provide weather and road surface condition data to centers.

Roadway Traffic Information Dissemination

• The field element shall include dynamic messages signs for dissemination of traffic and other information to drivers, under center control; the DMS may be either those that display variable text messages, or those that have fixed format display(s) (e.g. vehicle restrictions, or lane open/close).
• The field element shall provide operational status for the driver information systems equipment (DMS, HAR, etc.) to the center.
• The field element shall provide fault data for the driver information systems equipment (DMS, HAR, etc.) to the center for repair.

TMC Environmental Monitoring

• 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 roadway maintenance operations, and environmental data collected from sensors deployed on and about the roadway.
• The center shall provide weather and road condition information to weather service providers and center personnel.

TMC Traffic Information Dissemination

• The center shall remotely control dynamic messages signs for dissemination of traffic and other information to drivers.
• The center shall collect operational status for the driver information systems equipment (DMS, HAR, etc.).
• The center shall collect fault data for the driver information systems equipment (DMS, HAR, etc.) for repair.
