The confirmations by the several States of the tentative routes adopted by the Board at the full meeting of August 3-4 were considered final, and the routes are shown on the map accompanying this report and are described in terms of the control points of the federal aid system, as already approved by the Secretary of Agriculture in Appendix VI.
Attention is called especially to the fact that the procedure of the Board gave every State easy and ample opportunity to submit its own original suggestions and recommendations; to review these after action by the Board in making such adjustments as were deemed necessary or desirable to effect a satisfactory distribution of routes and connections at state lines; and finally to make additional changes in cases where a State believed the Board had failed to give consideration to all the pertinent facts or had acted on insufficient or faulty data.
The Method of Arriving at Uniform Designs for Markers and Signs
At the April meeting of the Board a design for a standard route marker was suggested. The design was sent to all the States with a request for comments on that design, or suggestions for some other one suitable for the purpose. Actual samples wore made of the suggested design in pressed metal, in cast aluminum and in cast iron to demonstrate the practicability of the design and get some idea of its probable cost. The adopted design was based on the results of the above procedure.
In arriving at a decision relative to the large variety of other signs and markers required in a uniform series a comprehensive study of all standardized signs available was made by a special committee of the Board and a series of designs in colors was worked out and submitted to the Board at the August meeting. In the final results the Board has embodied the recommendations of all the best thought on the subject with possibly one exception where there is still some disagreement. This detail involves the color code and is not considered vital. In general the details of the designs are based on the recommendations of the American Association of State Highway Officials supplemented by the work of the American Engineering Standards Committee and its numerous sponsor bodies. These details include shape, symbol, significance, color code and other details of design where such are prescribed. A complete set of directional, caution, danger signs and route markers are submitted with this report as Exhibits. The designs show colors and dimensions and all designs are so devised that they are subject to reproduction in pressed metal, cast iron, cast steel, cast aluminum and wood. The report of the sub-committee on signs is attached as Appendix VII.
