Saudi Arabia’s Roads General Authority (RGA) has introduced a set of design criteria for the construction and development of safe roundabouts, in line with the standards outlined in the Saudi Road Code.
The authority emphasised the critical importance of providing sufficient road width to accommodate all types of vehicles, including large and heavy trucks. It also said that ensuring adequate space is essential not only for maintaining smooth traffic flow but also for safety, particularly at busy intersections where diverse types of vehicles converge.
The RGA also emphasised the proper design of medians, that they must offer enough space to facilitate safe vehicle turning without encroaching into the lanes of oncoming traffic. Maintaining clear sight-lines at all points within the roundabout is a key consideration, enabling drivers to make well-informed, timely decisions, thereby reducing the potential for collisions.
In addition, the authority highlighted the necessity of installing clear and effective signage around roundabouts to navigate and alert drivers to the correct lanes and exits. It stressed that signage should be highly visible and intuitively placed for both local and visiting road users.
Furthermore, the RGA called for roundabouts to be designed with a strong focus on minimising accident risks. Special attention should be given to the safety of vulnerable road users, such as pedestrians and cyclists. This includes implementing designated crossing areas, appropriate traffic calming measures, and visibility that encourage cautious driving behavior.
Overall, these updated design guidelines reflect the RGA’s commitment to improving road infrastructure, promoting traffic safety, and supporting the Kingdom’s broader efforts to modernise its transportation systems in line with Vision 2030 objectives.
