History: A Move to Intelligent Highways
In 1985 Barrier Systems, Inc. introduced the Quickchange Moveable Barrier (QMB), the low cost solution for adding lanes for rush hour traffic to reduce congestion, improve safety and increase traffic throughput. By making an essentially immoveable object moveable, we created a new tool to help increase the effective capacity of our nation’s congested highway system.
