Functional Areas
MCM Environmental Information Collection
- 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), da
- The center shall collect environmental probe data (air temperature, exterior light status, wiper status, traction control status, etc.) from short range communications equipment that communicates with appropriately equipped probe vehicles.
- The center shall collect fault data for the roadside and vehicle-based environmental sensor equipment for repair.
- The center shall collect operational status for the roadside and vehicle-based environmental sensor equipment.
- The center shall provide weather and road condition information to weather service providers and center personnel.
- The center shall remotely control environmental sensors on-board maintenance and construction vehicles that measure road and weather conditions including air and surface temperatures, wind speed, humidity, precipitation, visibility and other measures.
- 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 respond to control data from center personnel regarding environmental sensor control and weather data collection and processing.
Roadway Environmental Monitoring
- The field element shall include environmental sensors that measure weather conditions including temperature, wind, humidity, precipitation, and visibility.
- 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 provide environmental sensor equipment fault indication to the controlling center or maintenance vehicle.
- The field element shall provide environmental sensor equipment operational status to the controlling center or maintenance vehicle.
- The field element shall provide weather and road surface condition data to centers.
