The final report for Innovative “Intelligent” Awareness System for Roadway Workers Using Dedicated Short-Range Communications, submitted by Darrell S. Bowman and Dr. Tom L. Martin, has been released.
Report 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.

The CVI-UTC recently participated in the Northern Virginia Transportation Career Fair, a VDOT-sponsored event which contributes to the education and recruitment of the transportation industry’s future workforce. CVI-UTC research was displayed and demonstrated to more than 1,300 high school students to showcase the benefits of careers in transportation and inspire students to consider transportation-related fields while they make their future career goals and plans.
