Dear Mr. Brinkmeyer

Thank you for your March 15 letter faxed to Mr. Ernest Huckaby of this office. Your letter requested approval to experiment with a pattern of transverse markings for speed reduction on Texas Farm to Market Route 362 near Houston. Your experimentation is part of the Traffic Control Devices Pooled Fund Study (TCD PFS), and the evaluation will be conducted by the Federal Highway Administration's Turner-Fairbank Highway Research Center.

We have reviewed your proposed experimentation and your evaluation plan, which will be identical to those approved for New York State in experimentation 3-161 (Ex). Your experimentation request is approved for a 2-year time period. For future reference purposes, we have assigned the following official experimentation number and title to your request: "3-165(Ex)-Speed Reduction Markings Texas DOT." Please refer to this number in future correspondence.

Thank you for your interest in improving traffic safety and for your participation in the TCD PFS. We hope your experimentation is successful and we look forward to receiving your reports as the experimentation progresses. If we can be of further assistance, please contact Mr. Scott Wainwright of our staff on 202-366-0857.

Sincerely yours,

Regina S. McElroy
