Smart Barrel Work Zone Safety Distributed Queue
Warning System Evaluation
System
highlights:
•Designed
to adapt in real time to upstream of the work zone line
•The
smart barrel contains a
passive infrared speed sensor
with an adjustable signaling system and communicates with a central controller
Findings:
•Drivers
reported that the adaptive system was more helpful than static road signs
•Analysis
of driving performance showed systematic improvement and suggested enhanced safety
