Traffic engineers have discussed the controversial subject of allowing drivers to make a right-turn-on-red (R.T.O.R.) for many years. There have been many strong points given for and against allowing this movement.
Within this paper R.T.O.R. is discussed and conclusions are drawn for a research of literature and questionnaire survey.
Questionnaires were sent to ninety-three cities and all fifty states. Many valuable unwritten facts and opinions were received from the seventy city and thirty-six state traffic engineers that completed and returned the questionnaires.
It was determined that 63.8% of the states replying and 64.3% of the cities are presently utilizing R.T.O.R. Since 1967, R.T.O.R. has been implemented by 47.8% of the states and 31.1% of the cities who indicated they are presently using it.
Traffic engineers seem to agree that nonuniformity in signing, warrants, and regulations are the main problems which hinder the effectiveness and acceptance of R.T.O.R.
R.T.O.R. is a valuable traffic tool that is rapidly being accepted by drivers, pedestrians, and traffic engineers. Like many other popular good things it will also become better with age. --Abstract, page ii
