MC11-Environmental Probe Surveillance (Service Package*)
This service package collects data from vehicles in the road network that can be used to directly measure or infer current environmental conditions. It leverages vehicle on-board systems that measure temperature, sense current weather conditions (rain and sun sensors) and also can monitor aspects of the vehicle operational status (e.g., use of headlights, wipers, and traction control system) to gather information about local environmental conditions. It includes the on-board vehicle systems that collect and report environmental probe data, the infrastructure equipment that collects the probe data and the centers that aggregate and share the collected probe data.

The following discusses how the National ITS Architecture provides the transportation service described by this service package. Each numbered item describes the operation of that portion of the service package identified with the corresponding number on the transaction set diagram.
Vehicles monitor the operational status of the Basic Vehicle equipment (basic vehicle measures) to sense when the headlights are on, wipers are activated, traction control systems have been engaged, etc. The Vehicle Subsystems is also equipped with environmental sensors measuring temperature, precipitation, and other conditions from the Roadway Environment (environmental conditions) as well as the geometric features of the roadway, e.g., sharp turns, lane positioning, etc. (roadway characteristics). The Vehicle subsystem takes this collection of data from on-board and passes the (environmental probe data) to the Roadway Subsystems' roadside equipment using Field-Vehicle Communications or directly to an Information Service Provider (ISP) over a wide area wireless network.
The Roadway Subsystem (RS) takes the collected environmental probe data from the passing vehicles and forwards it on to the ISP. In some cases, the roadside equipment that has collected this probe data may be able to send its data directly to a Maintenance and Construction Management Subsystem (MCMS) to support its collection of environmental data or directly to a Surface Transportation Weather Service or Weather Service terminators.
The ISP collects all of the environmental probe data from the probe vehicles within its network and aggregates the data in order to send road network environmental probe data to the MCMS, a Surface Transportation Weather Service, or the Weather Service.
