Impact of Perceptual Treatments on Driver's Behavior: From the Driving Simulator Studies to Field Tests--First Results

The present research was done in the context of the French national multidisciplinary research project, PREDIT-SARI. This study focused on the risk related to crest vertical curves (CVC) on rural roads, using a field site proposed by a local operator of the French road network (Conseil Général de Maine-et-Loire, 49). The final goal was to test one road treatment on the real road. A first step, by using driving simulators, has determined the two most effective perceptual treatments (i.e., rumble strips on both sides of the centerline and sealed shoulders) in order to help drivers to maintain lateral control when driving on CVCs. In the second step, in order to evaluate the impact of perceptual treatment on the field site, a diagnostic device was developed and installed, in order to track the individual trajectories of vehicles around the target CVC in the field site. This device is composed of fiber Bragg gratings, resistive sensors and inductive loop detectors. By using this trajectories observatory, the third step has consisted to collect the data during two periods. The first one before the setting-up of the centerline rumble strips (CRS), and the second one after the setting-up. In this way, the authors have evaluated the impact of the CRS on the driver's behavior, and the authors have compared the results obtained in the field study with those of the driving simulators’ studies. This comparison has highlighted that the trends observed both on driving simulators and on the real site are similar.
