Dear Mr. Curtit:
Thank you for your October 3 letter regarding your request to experiment with pedestrian countdown signals at two intersections in Columbia, Missouri. We have reviewed the material that was submitted and find it to be suitable in support of your request to experiment. Therefore, your request to experiment for one year under the provisions of the Manual on Uniform Traffic Control Devices with pedestrian countdown signals is hereby approved.
To be consistent with other experimentations on pedestrian countdown displays being conducted around the country (including elsewhere in Missouri), it is requested that your experimentation at the two intersections in Columbia include the following:
In your pedestrian surveys, please make sure the questions are asked in a manner that will indicate whether the pedestrian understands what the signal indications mean. Please include the following question, "Do you interpret the combination of the flashing DONT WALK and the numbers to mean it is legal to enter the crosswalk on a flashing DONT WALK as long as you can reach either the median or the other side prior to the countdown device reaching zero?" We also suggest you phrase questions so the pedestrian has to explain or select the meaning of the indications (multiple choice answers). For example: What does the WALK indication mean? What does the flashing DONT WALK mean? What does the solid DONT WALK mean? What do the numbers indicate to you? Do you cross any differently with the countdown signal than with traditional pedestrian signals?
We would appreciate receiving your schedule for implementation and submission of evaluation reports based on this approval of experimentation. At your convenience, please fax a copy of your updated schedule to Mr. Scott Wainwright at 202-366-3225.
For future reference purposes, we have assigned the following official experimentation number and title to your request: 4-236(Ex)--"Pedestrian Countdown Signals-Missouri DOT#2." Please refer to this number in future correspondence. Thank you for your interest in improving pedestrian safety.
Sincerely yours,
Shelley J. Row, P.E.
