4. Conduct evaluation of subsystems: In this task, the planned field evaluation method was
pilot tested through experimental evaluations of individual subsystems of the STC; this was
based on adapting the conceptual original equipment manufacturer (OEM) STC system to a
temporary, non-destructive platform that could be installed in participants’ own vehicles for
several weeks.
5. Build and demonstrate to NHTSA the prototype car: STC functionality was built into a
dedicated prototype vehicle; the car was demonstrated to NHTSA and agency feedback was
incorporated into refinements of the system.
6. Conduct stakeholder outreach and evaluations of prototype vehicles, develop parent/teen
information program: The prototype STC car was demonstrated to the expert community
through demonstration drives and feedback was provided. Feedback from automotive
OEMs was also solicited through phone and e-mail discussions. Subsequently, the full
integrated STC concept was field-tested with a group of teen drivers, again adapting the
conceptual OEM STC system to a temporary, non-destructive platform that could be
installed in participants’ own vehicles.
7. Document final specifications: Formal performance specifications for the STC were
developed and documented.
8. Generate final report and briefing: The final report was developed and a briefing was
provided to NHTSA.
