Examination of Driver Performance and Distraction with In-Vehicle Signing

The Minnesota Department of Transportation (MnDOT) conducted a demonstration project as part of the Connected Vehicles Program to design, build, and test new software applications to run on a commercially available mobile device (e.g., smartphone or personal navigation device). The goal of the overall project was to improve safety and mobility for drivers. As part of this work, the HumanFIRST Lab at the University of Minnesota tested three conditions in a driving simulator using a smartphone interface to display in-vehicle signing information (speed limit changes, construction zones, and school zone and curves) with and without navigation information present. In all conditions, the static roadside signs also appeared in the simulation in the appropriate locations on the roadway. One question not answered in the three conditions funded by the MnDOT contract was how drivers performed in the absence of the roadside signs. There is some evidence to suggest that in-vehicle alerting can augment the presence of roadside static signs but do not work well as a complete replacement. To answer this question, the HumanFIRST Lab funded a fourth condition in which the static roadside signs were removed from the simulation and the driver was required to complete the simulated drives with only the in-vehicle signing information. Because of funding constraints, the researchers were unable to continue the work and finish the data analysis. However, the interest in the work completed for MnDOT at the Transportation Research Board's Annual Meeting in 2013 suggested a need to determine how well drivers perform with just in-vehicle information. This need exists because the Vehicle-to-Infrastructure (V2I) Program includes the possibility that more roadway signs and information can be conveyed in-vehicle, thus eliminating the need for placement and maintenance of certain roadside signs. Providing drivers with safety-critical road information inside the vehicle rather than through dynamic signing offers an opportunity to meet USDOT goals for the Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) Programs.
