INFORMATION WAS COMPILED FROM REPORTS SUBMITTED FROM THIRTY-EIGHT STATES AND THE DISTRICT OF COLUMBIA ON THE STATUS OF MOTOR VEHICLE TRAFFIC CONTROL. IT SEEMS THAT THE TENDENCY TOWARD CENTRALIZING CONTROL OF TRAFFIC IS SPREADING RAPIDLY. THE INFORMATION RECEIVED IN REPLIES TO THE INQUIRIES SENT TO ALL STATES IS SUMMARIZED BY QUESTION.
