Research was undertaken to design, develop, and evaluate interfaces for a signalized- and stop-controlled violation warning system. Both infrastructure-based warnings (Driver Infrastructure Interface, DII) and vehicle-based warnings (Driver Vehicle Interface, DVI) were considered. The developed interfaces were tested by placing a driver in an instrumented vehicle on a closed test course with a working signalized intersection. The goal of the effort was to determine which DIIs/DVIs were most effective based upon the time to intersection at which the DII/DVI elicited the correct driver response of braking by the stop bar. While the DIIs that were tested were shown to be largely ineffective for violation warning, results showcase the potential of several DVI modalities, by themselves or in combination, to provide effective warnings to a driver violating a signal- or stop-controlled intersection. Furthermore, results indicate that a DVI warning combined with a vehicle's enhanced braking capability (brake precharging and panic brake assist) may enhance the range of acceptable DVIs.
