Round St, also known as Round Straight, is a type of road design that allows for safer and smoother turns. This design has several benefits and has been implemented in many areas around the world. In this article, we will discuss the advantages of Round St, how they work, and why they are a good choice for traffic flow.

1. Safety

One of the main benefits of Round St is enhanced safety. With traditional intersections, left turns can be particularly dangerous, especially with heavy traffic. However, with Round St intersections, there are no left turns. Instead, drivers must turn right and then loop around the roundabout to change directions. Studies have shown that this type of intersection reduces the number and severity of accidents by up to 75%.

Moreover, Round St intersections eliminate head-on collisions, which are often fatal. Vehicles approaching a Round St must slow down, and as a result, the impact speed during an accident is much lower than with traditional intersections.

Additionally, Round St intersections have better visibility and fewer blind spots because the view of oncoming traffic is not obstructed by turning lanes or other vehicles waiting to turn. This enhances the visual communication between drivers and improves safety.

2. Traffic Flow

Round St intersections not only enhance safety but also improve traffic flow. Because there are no left turns, there are no conflicts between opposing traffic, and the intersection can handle more cars per hour. Vehicles can approach from different directions, and instead of being forced to wait for a green light, drivers can enter the Round St when it is safe to do so. This reduces wait times, which reduces congestion, and helps to reduce rush hour delays.

Moreover, the design of Round St intersections encourages drivers to slow down and be more cautious. The roundabout design reduces the possibility of high-speed crashes, which can cause congestion and further delay traffic. As a result, Round St intersections take up less space, reduce fuel consumption, improve air quality, and reduce noise pollution.

Finally, Round St intersections are more efficient for pedestrians and cyclists as well. Because traffic is moving slowly, pedestrians and cyclists can cross the street safely. Additionally, due to the lack of stoplights, Round St intersections reduce pedestrian crossing times, thereby facilitating safe and timely crossing.

3. Design

The design of Round St intersections may vary slightly, but they all share a standard set of features. They have a central island, which may be landscaped or left bare for maintenance purposes. The island may also have a monument or a sculpture. There are one or two lanes depending on the size of the intersection. The design of the lanes guarantees that vehicles travel around the intersection in the same direction.

A typical Round St may have one, two, or three exits depending on the location. The exits are usually marked with pavement markings, signs, and arrows to guide drivers. The design ensures that vehicles entering the Round St always yield to those already inside. This type of intersection is available in different sizes, from small ones suitable for rural intersections to larger ones that can handle busy city traffic.

Finally, Round St intersections require less maintenance, as they don’t use cumbersome traffic signals that need repairs and replacements often. The central island merely requires basic landscaping, and the pavement markings eventually wear out, requiring minimal upkeep costs.


Round St is a modern intersection design that improves road safety and facilitates traffic flow. With fewer conflicts between vehicles and enhanced visibility, Round St intersections reduce the number and severity of accidents. Moreover, because drivers can enter and leave the intersection without stopping, Round St improves traffic efficiency while reducing congestion levels. Lastly, the Round St design can complement the aesthetic appearance of the surrounding landscape and is more cost-effective to maintain than traditional intersections.
