SEE THE SIGNS

Uncategorized, by Catherine Higgins.

UDOT is improving the safety in a location that has recently seen some tragic crashes.

State Route 201 meets SR 202 in Tooele County.

State Route 201 meets SR 202 in Tooele County. Traffic on SR 201 can be fairly heavy and fast while traffic on SR 202 is very light. Crashes that occur at the location tend to be severe due to the speeds on SR 201 and the angle of the crashes. Motorists going both directions are sometimes surprised by slower traffic entering from SR 202, and when crashes occur, cars on SR 201 hit oncoming traffic at an angle.

Alex Fisher is an intern at UDOT

A UDOT intern has researched a way to warn motorists on both routes to be aware of oncoming traffic. Her research is seeing fruition – new signs with auto-activated warning signs with flashing lights will be installed soon.

Alex Fisher is an intern soon to be Rotational Engineer at UDOT. Her assignment to find improvements for SR 201 and 202 led her to look at research done by engineers in Missouri. In an intersection with similar characteristics, auto-activated signs resulted in 51 percent reduction in crashes and a 77 percent reduction in sever angle crashes. Since Missouri has similar specifications for intersection configuration, speed and signs, Fisher believed auto-activated warning signs would work in Utah too.

Fisher proposed using LED stop signs on SR 202 and LED message signs on SR 201. UDOT Central Traffic and Safety liked her proposal and has designed the project.

Sign operation

Radar detection will trigger the lights on the signs to activate when traffic is approaching. The stop signs on SR 202 have LED lights on the perimeter. Under the stop sign, a LED message sign will display the text “cross traffic does not stop” when traffic is approaching. On SR 201, message signs with the words “watch for entering traffic when flashing.”

According to UDOT Region Two Traffic Engineer Robert Miles, Fisher did an excellent and thorough job with her research and proposal. The project was handed off to Rotational Engineer Brandon Weight for design. Check back to see an update of the project after construction.
