• Abstract:
  Roadside workers and emergency responders, such as police and emergency medical technicians, ; are at significant risk of being struck by vehicular traffic while performing their duties. While ; recent work has examined active and passive systems to reduce pedestrian collisions, current ; approaches require line of sight using either laser-, infrared-, or vision-based systems. We ; addressed this problem by developing a Global Positioning System (GPS)-based solution that ; equips roadside workers and vehicles with GPS units to estimate the trajectory of oncoming ; traffic, and to estimate whether worker strike is imminent. The results of our study show that our ; approach is 91% accurate in alerting the worker and vehicle of collisions and near misses. ; Furthermore, accurate warnings can be provided 5 to 6 seconds before any potential collision, ; allowing time for mitigating solutions.
