The comments on existing traffic signs sent to us at our invitation by organisations interested in this problem, have been most helpful, and we are grateful to them for their co-operation.
The investigations and experiments conducted by the Road Research Lab oratory have been of basic importance to this report and our thanks are due, not only to Mr. Moore and Mr. Christie, who were members of the Working Party, but also to the other members of the staff of the Laboratory, for their assistance in the preparation and demonstration of signs both on the roadside and in simulated conditions to test various lighting.
To Mr. Jock Kinneir, our designer, we are grateful for assisting us with so many difficult problems of design and for the production of sign layouts and alphabets.
We wish to express our appreciation of the help we received from the Working Party, which was admirably led by Mr. T. G. Usborne. They had to give great attention to detail and they bore the long hours of work cheerfully.
In conclusion we would like to pay tribute to our Secretary, Miss J. E. Chamberlain, who has borne a very heavy burden with great ability and endurance.
