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 Commercial Vehicle Administration Subsystem (CVAS) maintains the required safety reports in support of a roadside safety inspection. CVAS can communicate with Other CVAS' to exchange safety inspection reports (safety inspection report) with other jurisdictions. CVAS will send the safety inspection report to the Commercial Vehicle Check Subsystem (CVCS) and the Enforcement Agency. On an asynchronous basis, the Enforcement Agency can provide CVCS with information about commercial vehicle violations (information on violators). In addition, regional or national Alerting and Advisory Systems can provide both CVAS and CVCS with alerts and advisories.

The Commercial Vehicle Administration Subsystem (CVAS) maintains the required safety status, the safety portion of the CVISN "snapshot", in support of a roadside safety inspection. CVAS can communicate with Other CVAS' to exchange safety status information with other jurisdictions. CVAS will make safety status information available to the Commercial Vehicle Check Subsystem (CVCS) to ensure it has the most up-to-date information to support the roadside safety inspections. To further support the safety inspections, CVAS can also provide CVCS with accident reports and citation data that it has collected as well as providing the most recent updates of the credentials information and credentials status information. CVAS will also send information about a carrier's involvement in enforcement programs (carrier participation report) and commercial drivers licensing to the roadside (cv driver record).
-
On an asynchronous basis, the Commercial Vehicle Driver can send driver and vehicle information to the Commercial Vehicle Subsystem (CVO driver initialization).
-
The entire process is under the asynchronous monitoring (CVO inspector information) and control (CVC Override Mode) of the CVO Inspector.
-
On an asynchronous basis, the Commercial Vehicle Check Subsystem (CVCS) can detect and identify the Basic Commercial Vehicle using non-ITS equipment to visually determine the identity of the vehicle (USDOT number, license plate, etc.) (identification information) and the vehicle characteristics (size, number of axles, use of trailer, etc.) (CVO weight and presence). Alternately the CVCS can request data from CVS to be transmitted electronically, including identity and credentials data (request tag data), safety information (safety inspection request), or information concerning the freight or cargo (electronic lock data request). The commercial vehicle driver's credentials can be read directly from an electronic Driver Identification Card (cv driver credential) and CVS will send the identity/credentials data it maintains on-board including tag data, inspection data (safety inspection record), or cargo data (electronic lock data). At the end of the inspection, CVCS can send the results back to the CVS (safety inspection record).
-
After analyzing the safety data, a decision is made to either allow the vehicle to pass or require it to be stopped. The Commercial Vehicle Check Subsystem can send the decision to the Commercial Vehicle Subsystem (pass/pull-in), which will forward the data to the Commercial Vehicle Driver (CVO pass/pull-in message). Alternately the Commercial Vehicle Check Subsystem can send the decision directly to the Commercial Vehicle Driver (CVO pass/pull-in message) using a roadside sign.
-
If the commercial vehicle was pulled-in for inspection, the CVO Inspector can perform a safety inspection and send the results to CVCS, CVO inspector input. After the safety inspection, CVCS can send the report to CVAS (safety inspection report), which can be sent to the Fleet and Freight Management Subsystem (FFMS), safety inspection report. FFMS will take the necessary actions and submit a cv repair status to CVAS to indicate what maintenance items were performed.
-
If any statutes or regulations were violated, the Commercial Vehicle Check Subsystem can send information on violators to the Commercial Vehicle Administration Subsystem and Enforcement Agency (violation notification). CVAS will also forward the notices to the Enforcement Agency (violation notification).
-
Similarly, if a citation was issued during the inspection process, the Commercial Vehicle Check Subsystem can send this data to the Commercial Vehicle Administration Subsystem (citation) for distribution to the Enforcement Agency (citation) and the Fleet and Freight Management Subsystem (citation).
-
Similarly, if an accident report was generated during the inspection process, the Commercial Vehicle Check Subsystem can send this data to the Commercial Vehicle Administration Subsystem (accident report) for distribution to the Enforcement Agency (accident report) and the Fleet and Freight Management Subsystem (accident report). On an asynchronous basis, the Commercial Vehicle Check Subsystem will update the Commercial Vehicle Administration Subsystem with a record of daily activities, including summaries of screening events and inspections (daily site activity data).
