Some new, high tech signs have been installed along I-94 in southwest Michigan. Michigan Department of Transportation spokesperson Nick Schirripa tells us these dynamic signs feature color displays and several sensors to measure conditions that affect the safety of the road.
“The atmospheric sensor pays attention to visibility, precipitation,” Schirripa said. “Speed sensors will read the speed of traffic moving by. So, whether it’s moving at or near posted speed or slower than posted speeds. And then pavement sensors. So, pavement conditions.”
The dynamic signs will post suggested variable speed limits based on weather and road conditions. Schirripa says a study of the I-94 corridor a few years ago prompted MDOT to seek ways to help out drivers when things are rough.
“What we discovered was the stretch of I-94 through Van Buren County sees not only the most severe winter weather of any stretch of I-94, but also sees the highest frequency of crashes during the winter months.”
Eleven of the signs are being put up between US-131 and I-196. Schirripa says they’re the first of their kind in the state, with all sorts of sensors and cameras sticking out. Their total cost was $4.9 million. The signs will go online in the next month or so.
