This section gathers all the private vehicle scenarios and the commercial vehicle scenarios that were chosen as illustrators of particular characteristics for the task analysis. The purpose of this section is to illustrate the task breakdown for each individual scenario, so that it is easier to integrate the nature of the interactions between the ATIS-related tasks and the driving-related tasks.

To facilitate the reader's understanding, this section has been divided into two major portions: (1) all the private vehicle scenarios, and (2) all the commercial vehicle scenarios. For each scenario, the following information is provided: (1) a summary of the scenario's purpose and a brief description of the systems and functions used, (2) a graphical representation of the function interactions, (3) an Operational Sequence Diagram (OSD) of the scenario, and (4) a task breakdown summarizing the driver's activities believed to occur during the scenario.

Assumption. In some of these scenarios, it is assumed that some of the pre-drive activities have already been completed due to the nature of the scenario's environmental conditions. However, the elements pertaining to ATIS may be included if they will be used as part of the scenario's conditions. In addition, in some cases, the scenarios do not describe the driving to destination and, as a consequence, the driving activities have not been included.
