Dear Mr. Smith:

Thank you for your February 10 letter requesting approval to experiment with a pattern of transverse markings for speed reduction on Mississippi Route 469 near Flowood. 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-Fairbanks 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: "3-164(Ex)-Speed Reduction Markings Mississippi 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
Director, Office of Transportation Operations
