• Abstract:
  The goal of the study was to examine the influence of in-vehicle signing (IVS) pertaining to four types of changing ; driving conditions and determine the utility and potential safety costs associated with the IVS information. Signage ; displayed on a personal navigation device was presented for specific zones within the simulation to assist drivers’ ; preparation for transitioning to new driving conditions ahead. These zones included: speed zone changes within the ; same roadway, notification of school zones, notification of work zones, and notification of curves. Driving ; performance measures known to be related to distraction as well as subjective usability and workload measures ; were used to help identify potential distraction associated with the IVS information. Moreover, risk analysis was ; conducted to evaluate the safety associated with IVS technology compared to the known safety levels with standard ; roadside signage. The objective measures collected in this study (both driving performance and risk analysis) ; indicated that implementing IVS technology would impact driving performance in the following manner: ;  When IVS was deployed in the absence of external signs, speeding behavior significantly increased relative ; to baseline levels. IVS technology was not observed to impact speeding behavior when external signs were ; also present. ;  Risk analysis suggested that IVS technology (when used in conjunction with external signs) can improve ; the safety associated with frontal-impact crashes; however, risk analysis proved that safety across all crash ; types was significantly reduced below baseline levels when IVS was used without external signs. ; Moreover, subjective usability results reinforced the driving performance findings.
