California Introduces Turbo Roundabout to Enhance Safety at Intersection

Introduction

Motorists in Hollister, California, are set to experience the state’s first turbo roundabout, a unique traffic intersection designed to improve safety. Turbo roundabouts, originally developed in the Netherlands, prioritize safety over speed with raised lane dividers that discourage lane changes within the circular structure. This innovative design aims to reduce accidents and enhance traffic flow at the junction of San Benito Routes 25 and 156.

Enhancing Safety with Turbo Roundabouts

Turbo roundabouts, despite their name, are not built for speed but for safety. Unlike traditional multilane roundabouts, turbo roundabouts guide drivers into the correct lanes before entering the intersection, eliminating the need for lane changes within the circle. By following their designated lane, drivers can easily navigate the roundabout and reach their desired exit.

Construction and Benefits

The construction of California’s first turbo roundabout began in the summer of 2022 and recently opened its third lane to traffic. The project, costing a total of $14.9 million, aims to reduce accidents at the problematic intersection of routes 25 and 156. According to Caltrans, the rate of crashes at this intersection was significantly higher than similar intersections across the state. Turbo roundabouts have proven to be effective in reducing injury-causing crashes by 76% compared to signaled intersections.

Expansion of Turbo Roundabouts

While Hollister residents will be the first to experience a turbo roundabout in California, they won’t be the last. The success of turbo roundabouts worldwide, including the first one opened in Jacksonville, Florida, in 2022, has prompted the Department of Transportation (DOT) to encourage more states to adopt this innovative design. The DOT recognizes the potential of turbo roundabouts in improving safety and traffic flow for all types of users, including multi-trailer transport trucks.

Conclusion

The introduction of turbo roundabouts in California marks a significant step towards enhancing intersection safety. With their proven effectiveness in reducing accidents and improving traffic flow, turbo roundabouts offer a promising solution for busy intersections. As more states embrace this innovative design, motorists can look forward to safer and more efficient journeys on the road.
