Notes:

1. Evaluation of Work Zone Barricades and Temporary Sign Supports, Mak, Bligh, and Menges Report No. 5388-1 Sponsored by the Texas DOT.

2. Evaluation of Work Zone Barricades, Mak, Bligh, and Menges Report No. TX-97/3910-S Sponsored by the Texas DOT.

3. The tested portable sign stands were supplied by Traffix Devices Inc. and MDI-Windmaster. Roll-up sign sheeting was supplied by Reflexite. Plastic barricade panels were also supplied by Traffix. The acceptable portable sign stands all featured horizontal cross braces of lightweight fiberglass or plastic elements. Recent testing of some portable sign stands at 90 degrees shows that horizontal cross braces of tubular metal penetrate the windshield and are not considered crashworthy without additional testing. Portable sign stands with horizontal metal tubes (or other inflexible elements) supporting flexible signs may not be used on the NHS in a position where they could be struck at right angles.

4. Horizontal and upright components of the hollow core recycled plastic barricades were supplied by Recycled Plastic Products, Inc.
