Crash history shows that motorists traveling in the right turn lane are much more likely to be involved in a rear-end crash than when traveling in any other lane. When several of Springfield’s busiest intersections were built, large-radius turn lanes were standard, allowing traffic to merge swiftly. However, crash data has since shown that turns with a large radius allow faster approach speeds and cause drivers to lose sight of the vehicle in front of them, resulting in rear-end crashes.
Through the voter-approved 1/8-cent Transportation Sales Tax, funding has been designated to make safety and capacity improvements to several Springfield intersections, with the goal of increasing right-turn lane safety.
“After several months, a crash study will be conducted comparing crashes before and after the installation,” said Public Works Traffic Safety Professional Mandy Buettgen-Quinn. “We will also evaluate the effect of the modified design on crashes, traffic flow, pedestrian safety and truck traffic. This information will assist with the future redesign of major intersections in a way that best suits our community.”
