Dear Mr. Richardson:
Thank you for your September 24 letter requesting permission to experiment with the school zone delineators produced by Davidson Plastics Corporation.

Section 1A.10 of the Manual on Uniform Traffic Control Devices describes a formal process to follow in requesting experimentation. There is a list of 8 items that are required as part of the evaluation plan when submitting a request for experimentation. These items are very important and each must be addressed individually in your request.

Item G, in particular, is important; it discusses the required research or evaluation plan. This plan should include such items as before/after speed studies, before/after crash statistics, etc. A brief discussion on how the data will be collected is also requested. Failure to address the requirements in Section 1A.10 may delay the approval process for the experimentation.

We require that the experimentation period be for a period of a minimum of 1 year. Tentative start and stop dates should be included in the plan.

Also, it is important to acknowledge that semi-annual reports will be provided along with a final report within 90 days of completion of experimentation.

For future reference purposes, we have assigned the following official experimentation number and title to your request: VII-41(Ex)-"School Zone Delineators." Please refer to this number in future correspondence.

If you need further assistance, please contact Ms. Cherie L. Kittle at 202-366-2188.

Sincerely yours,

Shelley J. Row, P.E.
