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.

  1. The driver activates or deactivates or adjusts performance parameters (e.g. sensitivity or contrast) of the system (driver inputs).

  2. The vehicle senses characteristics of the roadway (roadway characteristics) and environment and presents this as an enhanced image to the driver (driver updates).
