Why Do Stop Signs Have Eight Sides?
MSN | 9 July 2017
At the turn of the 20th century, American roads were chaos. Drivers didn’t need a license, lane lines didn’t exist, and stop signs hadn’t yet been invented.
When the first official stop sign did appear in Detroit, in 1915, it was small, white, and square, nothing like the red octagon we know today. But in 1923, a branch of Mississippi’s highway department suggested a change—what if a sign’s shape could denote the kind of hazard ahead? The logic was simple: The more sides a sign has, the more dangerous the upcoming stretch of road is.
Circles (which were considered to have infinite sides) designated the riskiest hazards, like railroad crossings. Octagons denoted the second most perilous hazards, like intersections. Diamonds signaled less-tricky stretches, and rectangles were strictly informational. We still use these parameters today, though no one knows why the nonagon drew the short stick.
ចុម! អ៊ីចឹងទេ !?
ReplyDeleteស្មានថា ៨ ជ្រុង ជាសញ្ញា ប្រាប់ពី អដ្ឋង្គិកមគ្គ, the eight fold path to Sim city !
I am obliging myself to come back and clarify my silly joke which I made above as (10:56 PM). It was my poor choice of using the word អដ្ឋង្គិកមគ្គ which translated as Eightfold Path in Buddhist teaching.
ReplyDeleteI should have used the word អដ្ឋមុខ just likes in ចតុមុខ orចតុម្មុខ.
Someone might think that I poked fun of Buddhist teaching but believe me that, this was not the case.
I deliberately used the word eight fold path NOT Eightfold Path.
My other mistake was Sim city. It should have been of SimCity, the Electronic Arts game which I used to play for fun !!!
