About this file
This document provides specifications for an active vehicle barrier safety scheme for a roadway without a median. Key details include:
The scheme utilizes a combination of signs, pavement markings, vehicle detectors, an active vehicle barrier, audible alarms and blank-out signs to control traffic and provide a 5-second stop condition. Upon detection of an approaching vehicle, the signs and blank-out signs will activate to warn drivers and require them to stop. If a vehicle does not stop, the active vehicle barrier will deploy across the lanes after 5 seconds to physically prevent ingress. Retroreflective pavement markings and a solid white lane line between same direction lanes will also help control traffic flow and lane changing. Dual inductive loop vehicle detectors will be installed at the barrier to trigger activation. All components must conform to relevant MUTCD and state standards for design, construction and placement.
The related federal contract opportunity is for work at the Bulgaria Graf Ignatievo Entry Control Point and was solicited by the Department of the Army European Command.
