VDOT ESS Weather Platform

Status:

Existing

Definition:

This element is a ESS weather platform that obtains environmental conditions information from sensors along primary roadways. Weather conditions measured include Air Temperature, Relative Humidity, Wind Speed and Direction, Precipitation Type and Intensity, and Visibility/Air Quality. This information is available to those systems needing it. There are plans to add a Surface Transportation Weather and Road Conditions Platform element providing data to this element in the future.

Stakeholder:

VDOT Central Office

National ITS Architecture Functional Requirements
associated with VDOT ESS Weather Platform:

MCM Environmental Information Collection

1. 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.
2. The center shall remotely control environmental sensors that measure weather conditions including temperature, wind, humidity, precipitation, and visibility.
3. The center shall respond to control data from center personnel regarding environmental sensor control and weather data collection.
4. The center shall collect fault data for the roadside and vehicle-based environmental sensor equipment for repair.
5. The center shall collect operational status for the roadside and vehicle-based environmental sensor equipment.
6. 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.
7. The center shall remotely control environmental sensors that measure road surface temperature, moisture, icing, salinity, and other measures.
8. The center shall provide weather and road condition information to weather service providers and center personnel.

MCM Environmental Information Processing

1. The center shall respond to control data from center personnel regarding environmental information processing.
