This service package supports roadway service patrol vehicles that monitor roads that aid motorists, offering rapid response to minor incidents (flat tire, accidents, out of gas) to minimize disruption to the traffic stream. If problems are detected, the roadway service patrol vehicles will provide assistance to the motorist (e.g., push a vehicle to the shoulder or median). The service package monitors service patrol vehicle locations and supports vehicle dispatch to identified incident locations. Incident information collected by the service patrol is shared with traffic, maintenance and construction, and traveler information systems.

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 Emergency Vehicle (i.e., the service patrol vehicle) determines its location (position fix) and reports its position and status to the Emergency Management dispatch function (emergency vehicle tracking data). Service patrol vehicle location and status is reported to the Emergency System Operator (emergency operations status). When necessary, the Emergency System Operator can enter commands (emergency operations inputs) that result in emergency dispatch requests to the service patrol vehicle. The dispatched vehicle can acknowledge the dispatch request (emergency dispatch response).
At the scene of an incident, the service patrol vehicle can report the incident status to the Emergency Management dispatch function, which can relay the status as incident information to Traffic Management (e.g. reporting the severity and estimated duration of an incident), Information Service Providers (e.g. to report the incident information to their clients) and Maintenance and Construction Management (e.g. for incident cleanup) as appropriate.
