Personal Injury Attorney

While research has demonstrated that roundabouts are clearly a safer choice for motorized vehicle traffic and pedestrians, bicyclists, the most vulnerable users of roundabouts, are under studied in America. A personal injury attorney who practices in a high-growth metropolitan area, can help you recover for your damages if you have incurred injuries while walking, biking or driving on a roundabout.

The following list compiled by a personal injury attorney, includes various facts that have been reported about roundabouts, including geo-pattern guidelines and recommendations, and results from several studies of collisions occurring on roundabouts involving motorized vehicles, bicyclists and pedestrians.

  • In 2013, the United States had approximately 3200 roundabouts; France, the European country with the most roundabouts, reported more than 30,000 in 2013.
  • In 2016, France claimed one roundabout for every 45 intersections; in the United States one for every 1,118 intersections existed.
  • Driving instructors claim that more than half of their students are challenged by roundabouts.
  • Circular causeways have enjoyed popularity because the sites of conflict are greatly reduced in comparison to traditional intersections. A typical 2 lane 4-way intersection has 32 points of conflict: 8 merging; 8 diverging and 16 crossing. A roundabout has 8 conflict points: 4 merging and 4 diverging.
  • Geometric design engineers of roundabouts advise minimal use of signage (warnings, directional and landscape) to avoid distractions and line of sight obstructions. Most directional signs are painted on the surface of roadways.
  • Motorized vehicular speed is reduced on roundabouts by as much as 85%.
  • Right angle accidents on roundabouts have been reduced by 87%.
  • Casualty accident rates are reduced by 68% after roundabout installation.
  • European research on bicycle safety and roundabouts conclude that single-lane roundabouts are safer for cycling than double lane circles which are more stressful for cyclists to negotiate.
  • Nearly half of all collisions between bicyclists and motorized vehicles occur when a vehicle enters the circular roadway;
  • Bicycle accident rates at roundabouts are 15 times those of cars.
  • A study at 72 locations in Sweden concluded that bicyclists traveling single-lane roundabouts were injured in 22% less collisions than at other intersections; on multi-lane roundabouts, the risk of injury for cyclists was double that of motorized vehicles.
  • A study conducted in the Netherlands showed that a separate cycling track was the prudent place for cyclists to travel; a bike lane in the perimeter of the circulatory was least safe for cyclists.
  • A study conducted at two urban roundabouts in Minnesota concluded that the majority of drivers failed to yield to bicyclists at both roundabouts.
  • Roundabouts lead to a slight reduction in pedestrian injuries, while cycling injuries increase.
  • The yield marking should be parallel to the splitter island used by pedestrians to cross 2 lanes of traffic.
  • According to design guidelines, the pedestrian crosswalk should be offset by one to three car lengths from the yield line. While pedestrians are crossing, motorists can scan for an acceptable gap in traffic where they can safely merge into the circulator.
