Today’s drivers face different challenges
than in the past. Changes in driving patterns, increased distractions, and
advances in technology have all impacted driving conditions. In response to
these changes, improvements to road design have been developed, including the
Intersections are among the most deadly of road dangers. This is mainly
due to the speed of the vehicles when they fail to heed traffic controls,
whether that control be a stop sign, four-way stop, or traffic signal.
Roundabouts minimize this danger as they are designed to “calm” traffic by
lowering the speed of the vehicles as they enter the roundabout. Research
has found a 90% decrease in fatalities by construction of a roundabout over
the use of a signalized intersection, with a 75% decrease in injury crashes
and a 37% reduction in total crashes.
Authorities at the state and federal level have recognized the value of
roundabouts in increasing safety, reducing air pollution and fuel use, and
promoting traffic flow. To encourage the implementation of roundabouts, the
federal government provides grants to local agencies to help fund their
construction. This assistance allows road commissions to stretch limited
transportation dollars while improving traffic safety for the residents and
The St. Clair County Road Commission pursues every opportunity to
improve the safety and efficiency of the county’s road and bridge system.
Modern roundabouts represent one more tool used to achieve that important
