• Abstract:
  In the previous tasks we have conducted extensive analysis by the driving simulator and data analytics studies to validate the effects of speed management countermeasures on speed and non-motorist safety. The driving simulator tested the effects of Rectangle Rapid Flashing Beacon (RRFB), Pedestrian Hybrid Beacon (PHB), and speed feedback sign on speed choice. In this task, the research team developed various driving scenarios based on the findings that were reported in previous tasks. The driving simulator experiment in this task recruited participants, considering age and gender to reach more conclusive results. Both base scenario without any speed management countermeasures and scenarios with speed management countermeasures were developed for three design speeds corresponding to the specific context classification. Detailed vehicles’ trajectory data could be obtained from the driving simulator study. Speed metrics including mean speed and the 85th percentile speed, were analyzed to explore drivers’ speed choices at the upstream and downstream of the locations where the speed management countermeasures were placed.
