The purpose of this site is to help plan Work Zones.

The basic idea is to present basic information about barriers and attentuators in a format that will allow quick comparisons in support of Work Zone planning. The primary sources of the information presented here are NCHRP 350 approval letters. The next steps in developing these pages are to improve the information presented and to review the presentation format. This will require practitioner input.

This site is hosted by AHMCT at UC Davis. The content of these pages reflects work in progress. Please send comments to ahmctWeb (at)
