When was the MUTCD stop sign introduced?
The MUTCD stop sign was already widely deployed in the United States when the use of other types of stop signs was eliminated in 1966. In 1968, this sign was adopted by the Vienna Convention on Road Signs and Signals as part of United Nations Economic Commission for Europe 's effort to standardize road travel across borders. The Convention specifies that stop be written in English or the national language, and also allows a circular sign with red legend. Forty European countries are party to the convention.

Why are stop signs important?
Stop signs are often used in North America to control conflicting traffic movements at intersections that are deemed not busy enough to justify the installation of a traffic signal or roundabout. In the United States, the stop sign is not intended as a traffic calming device, but is meant to be installed mainly for safety or to assign right-of-way. Stop signs may be erected on all intersecting roads, resulting in an all-way stop. Some research has concluded that stop signs do not offer measurable safety benefits over the Yield approach. Other research has concluded that multiway stop signs do not effectively control traffic speeds, and can give rise to negative effects including increased traffic noise and pollution from braking and accelerating vehicles, enforcement problems, and reduced sign compliance.
How does a stop sign affect cross traffic?
Stop sign placement can pose difficulties and hazards in applications where cross traffic is not controlled by a sign or light. Relatively long distance between the stop sign and the crossroad facilitates accurate perception of the speed of approaching cross traffic, but lengthens the time and distance required to enter and clear the junction. Relatively short distance between the stop sign and the crossroad shortens the time required for safe passage through the intersection, but degrades the ability of the stopped driver to accurately perceive the speed of approaching cross traffic. Specifically, drivers approaching an intersection from beyond the subtended angular velocity detection threshold (SAVT) limit may be perceived by a stopped driver as standing still rather than approaching, which means the stopped driver may not make an accurate decision as to whether it is safe to proceed past the stop sign. Whether the distance between the stop sign and the crossroad is officially short or is shortened by drivers creeping past the stop line, they can lose the visual acuity of lateral motion, leaving them to rely on the SAVT. This can make it difficult to accurately estimate the movement of approaching cross traffic.

Why did the original stop sign have an octagon?
The octagon was also chosen so that it could be identified easily at night since the original signs were not reflective. The more urban-oriented National Conference on Street and Highway Safety (NCSHS) advocated a smaller red-on-yellow stop sign. These two organizations eventually merged to form the Joint Committee on Uniform Traffic Control Devices, which in 1935 published the first Manual on Uniform Traffic Control Devices for Streets and Highways (MUTCD) detailing the stop sign's specifications.
