Final week one in every of my Fb associates, David Pryor of Springfield, posted a wierd photograph.
It was an image of two similar visitors lights — on two posts mounted within the floor — standing aspect by aspect like sentries on the east aspect of Grant Road, at West Nichols Road.
Was this a case of double imaginative and prescient?
I rubbed my eyes and, no, they have been each nonetheless there.
So, the query is:
Why two? Why two?
Who higher to reply this query than Springfield’s Mr. Visitors Engineer —that is his title — Eric Claussen?
Claussen began his rationalization by quoting the Bible.
Not that Bible, however the holy e-book of visitors engineers: “The Guide on Uniform Visitors Management Units,” revealed by the Federal Freeway Administration.
The nationwide guideline is that there ought to all the time be two visitors alerts dealing with every path.
The aim of the redundancy is, in fact, two-fold, Claussen says.
First, it supplies higher visibility.
On this case, visibility is a specific concern as a result of Nichols — the east/west road — isn’t a straight shot via Grant. The intersection is barely off-set.
Second, visitors-mild bulbs are identical to mild the bulbs you purchase on your house: They do not burn out at the very same time. So when one goes darkish, there’s nonetheless one in operation.
Claussen says the 2 visitors-mild submit has been there at the least so long as he has labored for the town, which is eleven years.
He theorizes that the rationale they weren’t positioned on a single pole with an arm extending into the intersection is due to the facility strains overhead.
“It is a type of intersections that I’ve pushed via about 500 occasions — you understand the 2 posts are there, however you simply cease considering it’s any totally different than another intersection,” Claussen says.
