AVSS06-Pre-Crash Restraint Deployment (Service Package*)
This service package provides in-vehicle sensors and on-board communications to monitor the vehicle's local environment, determine collision probability and deploy a pre-crash safety system. It will include on-board sensors to measure lateral and longitudinal gaps and together with weather and roadway conditions will determine lateral and longitudinal collision probability. It will exchange messages with other equipped vehicles to determine the precise location of surrounding vehicles. It will deploy a pre-crash safety system when a crash is imminent.

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.
The physical presence of potential obstacles and basic vehicle measures (e.g. speed, acceleration in all 6 degrees of freedom) are combined to identify conditions where a collision is likely, and to then deploy vehicle restraints (e.g. pre-tension safety belts) in advance of the collision.
The VS will also exchange vehicle safety data with other equipped vehicles within the range of the Vehicle-Vehicle Communications. VS will use this information to help calculate probability of a collision and determine the need to deploy any pre-crash restraints.
