• Abstract:
  Work zones present an increased risk to drivers and the work crew. To mitigate these risks, this study investigated the ; potential effects of in-vehicle messages to communicate work zone events to the driver. The researchers conducted ; literature reviews on risks imposed by work zones, along with design guidelines for any in-vehicle messaging system. The ; researchers then conducted a work zone safety survey to illustrate driver attitudes in Minnesota toward work zones, along ; with smartphone use and in-vehicle messages through smartphones. The survey found that a significant number of drivers ; make use of smartphones in the automobile, and they placed these smartphones in various locations throughout the vehicle. ; The survey was followed by a driving simulation study that tested drivers in two different types of work zones. Participants ; drove through these work zones three times, each with different messaging interfaces to communicate hazardous events to ; the driver. The interfaces included a roadside, portable changeable message sign, a smartphone presenting only auditory ; messages, and a smartphone presenting audio-visual messages. There was better driving performance on key metrics ; including speed deviation and lane deviation for the in-vehicle message conditions relative to the roadside signs. ; Furthermore, drivers reported significantly less mental workload and better usability, work zone event recall, and eye gaze ; behavior for the in-vehicle conditions relative to the roadside sign condition.
