Brief Introduction on Road Deceleration devices
Road safety is a big issued that can’t be overemphasized, which, is ensured by the Deceleration devices installed on the road. This text is going to introduce several main devices that play an important role in slowing down traffic.
Convex marking lines are roughened surfaces that are either embossed or recessed. When a vehicle drives over them, they make a loud rumbling sound and vibration. They can be placed across traffic lanes to alert drivers that they are approaching a potentially hazardous location, such as a work zone or an isolated intersection. They are used along the shoulders or centerlines of highways to alert drivers that they are leaving their traffic lane.
A speed bump (also called a road hump, or undulation, and speed ramp) is a rounded traffic calming device used to often used to slow traffic down in areas where pedestrian traffic is present, such as offices, schools, shopping malls and residential roads. This improves the safety of vehicles and pedestrians in the area. It can also reduce vehicle volume on residential streets. Speed bumps are placed across the road to slow traffic and are often installed in a series of several bumps to prevent cars from speeding before and after the bump.
Road sign is a plate which conveys and manifests traffic laws and road information with certain graphic symbols. It enables a specific , vivid and also brief expression of traffic laws. Some road signs such as Speed Limit sign, Stop sign and many other signs that express the idea or information of limiting speed, slowing down are essential deceleration devices for traffic control.
As is known to all, road stud is mainly intended to remind the driver to ensure a safe driving, especially in the condition of rainy days or dark night. In addition to that, the road studs play an important role in warning the driver to stay cool when driving by producing bumpy effect for the driver when the vehicle run over them. if they are installed densely on the road, they can serve as the convex lines and bring the decelerating effect. However, only the total aluminum road stud possesses the character, which possesses high compressive resistance and is usually applied at the double amber lines.
