Abstract:

According to the strategic highway safety plans (SHSP) (American Association of State Highway and Transportation Officials (AASHTO) 2005), evaluating the impact on the performance of highway safety is required for any new safety device or treatment. Deployment of backlit LED illuminated STOP signs (BLS) has been proposed recently to improve safety at locations with known history or potential collision risk. While these signs are expected to affect traffic operations and road safety, the effects of such treatments are not yet fully understood. This research study investigates the effects of BLS on ameliorating traffic safety at stop-controlled intersections (SCI). This study benchmarked BLS with three other STOP signs with enhanced conspicuity properties at low visibility ambiance. An unbiased experiment was design in order to make a pairwise comparison of surrogate crash measures. A procedure for calibration and validation of a micro-simulation model was carried out to replicate the field observation. The number of conflicts at SCI with different treatment was estimated for rear-end and crossing movements. Overall the study demonstrated the usefulness of all four treatments while the LED and BLS having the highest impact on vehicle speed and compliance to the control device. Thus this research may represent a point of reference for engineers in adjusting or consideration of these type of treatment at hot spot SCIs.
