What is a common type of road safety intervention?

The installation of traffic signals or signs is a fundamental and common type of road safety intervention because these tools are specifically designed to manage and influence the behavior of road users. Traffic signals and signs play a crucial role in regulating traffic flow, indicating when vehicles and pedestrians should stop or go, and providing necessary information about road conditions, hazards, and rules. By directing and controlling the movement of vehicles and pedestrians, they help reduce the risk of accidents, enhance safety at intersections, and promote more predictable behaviors among all road users.

In contrast, while decorative flowers may enhance the aesthetic appeal of roadways, they do not contribute to safety. Building more lanes for faster traffic could potentially increase traffic speed and congestion, which does not inherently improve safety. Similarly, creating additional parking lots addresses a separate issue related to parking availability rather than directly enhancing safety on the road. Thus, the installation of traffic signals or signs is a direct and effective measure aimed at promoting road safety.
