Dear Mr. d’Escoto:

Thank you for your letter of June 13 requesting experimentation with yellow-green pavement markings for school zone crosswalks. We have reviewed your original request and the additional information provided in your July 17 letter, and we approve your request for experimentation.

For reference purposes, we have assigned your request the following official experimentation number and title: "7-39(E) - Yellow-Green Pavement Markings for School Zone Crosswalks." Please refer to this number in future correspondence.

Good luck with the project. We look forward to the results and the promise of a new traffic control device that may improve the safety of pedestrians. If you have any questions, please call Ms. Cherie L. Kittle at 202-366-2188.

Sincerely yours,

Shelley J. Row, P.E.
