MIDWEST STATES POOLED FUND PROGRAM
Annual Fee to Finish TF-13 and FHWA Standard Plans
Sponsoring Agency Code
TPF-5(193) Supplement 85
Each year, the Midwest States Pooled Fund program sponsors several roadside safety studies at the Midwest Roadside Safety Facility (MwRSF) of the University of Nebraska-Lincoln. Some of these research efforts result in the development of new roadside safety features. As part of this effort and on behalf of the member states, MwRSF seeks FHWA acceptance for those devices or systems meeting current impact safety standards. In the future, FHWA will require standard Task Force (TF) 13-format CAD details along with the typical system details when requests for hardware acceptance are made. MwRSF prepares 2-D and/or 3-D CAD details for newly-developed roadside safety features that are subjected to full-scale vehicle crash testing. The CAD details used to describe the as-tested systems or components are not always prepared and presented in the same format as now required by AASHTO TF-13 and FHWA. As such, additional CAD details and background information must be prepared when FHWA acceptance is sought under MASH or when the new system or associated components are submitted for inclusion in the electronic version of the barrier hardware guide.
In general, roadside safety hardware must be subjected to crash testing in order to evaluate its crashworthiness and demonstrate that it meets current impact safety standards. Over the last 50 years, a significant number of roadside safety systems and components have been successfully developed. The majority of these systems and standard components have been archived in various barrier guides. The most recent document was published by a consortium of AASHTO-ARTBA-AGC and was entitled, A Guide to Standardized Highway Barrier Hardware (May 1995).
More recently, AASHTO Task Force (TF)-13 has taken over the responsibility for updating the contents of the paper guide through its various subcommittees and converted the guide to an electronic, web-based format. For the updating process, standard TF-13-format CAD details are now required and subjected to review and comment by TF-13 members. Once the CAD details are deemed acceptable and meet TF-13 guidelines, they are integrated into the electronic, web-based version of the existing barrier hardware guide that is now maintained by Texas Transportation Institute personnel.
For all new barrier hardware, the member states request that MwRSF seek formal FHWA acceptance and placement of standardized TF-13 CAD details in the electronic version of the highway barrier guide. This funding shall be used to supplement the preparation of the TF-13 format CAD details.
Prepare CAD details for newly developed highway barrier hardware in order to comply with the TF-13 format.
Newly-developed highway safety hardware will be contained in the electronic, web-based guide, thus promoting the standardization of barrier hardware across the U.S. and abroad.
