(Harrisburg, PA) According to a release yesterday from PennDOT, PennDOT announced yesterday that roundabouts continue to provide safe, efficient travel across the Commonwealth. Findings in studies through 2024 with 20 years of crash data from roundabouts around Pennsylvania used confirmed that crashes decreased by 7 percent and crashes with injuries got reduced by 51 percent. 104 roundabouts across Pennsylvania have been built to improve the flow of traffic and/or decrease the severity of a crash and more than 30 additional roundabouts are in various stages of design and construction around Pennsylvania since 2005. According to that same release from PennDOT yesterday, here is some more information about roundabouts and some tips for safely driving on them:
- Pennsylvania data reflects national studies that found changing two-way sign-controlled intersections to a single-lane roundabout reduced injury crashes by more than 80 percent. Likewise, changing a signalized intersection to single-lane or multilane roundabout reduced crashes with injuries by up to 78 percent.
- The Federal Highway Administration (FHWA) lists roundabouts as a “Proven Safety Countermeasure” that improves safety by reducing vehicle speeds by angling incoming traffic. The crashes that do occur tend to be sideswipe crashes with vehicles traveling at slower speeds rather than T-bone or head-on collisions. Additionally, eliminating left turns across opposing traffic results in dramatically fewer injuries.
- In addition to safety improvement, roundabouts carry, on average, approximately 30 percent more vehicles during peak traffic than similar intersections. In off-peak hours, roundabouts cause almost no delay, compared to traffic signals.
- As roundabouts are constructed around the state, it is important to know how to correctly navigate them.
Here are a few key things to remember when navigating a roundabout:
- Slow down and be prepared to yield to pedestrians in the crosswalk.
- Circulating traffic has the right of way. Look left and check for approaching traffic. If there are multiple circulating lanes, yield to both before entering. Do not assume the vehicle in the inside lane will stay there.
- Do not stop while in the circulatory roadway, and always use your right turn signal to indicate your exit.
