Road barriers are essential for traffic management and safety. They control vehicle movements, prevent collisions, and reduce accidents. By absorbing impact energy, they protect drivers and pedestrians.
Different Types of Road Barricades
There are several road barriers types, each designed for specific purposes and locations.
Temporary Barriers
- Traffic cones are lightweight, portable devices made of brightly coloured plastic or rubber, used to temporarily redirect traffic or mark off areas for maintenance and construction. Their high visibility, often enhanced by reflective strips, makes them effective at catching attention. They are easy to deploy and remove, making them versatile for short-term projects, and offer quick setup, flexibility in placement, and effective traffic guidance around hazards.
- Barrels and drums are durable, cylindrical barriers used in construction and traffic control. Made from high-density polyethylene, they withstand impacts, provide continuous guidance, and are highly visible. Commonly used in roadworks and highway projects, they offer durability and safety while minimising vehicle damage.
- Plastic barriers come in water-filled and sand-filled types. Water-filled barriers are easy to transport and stabilise with water, while sand-filled barriers are pre-filled for durability and impact resistance. Both are robust, reusable, and effective for construction zones, road closures, and events, offering flexibility and impact absorption.
- A-Frame barricades feature sturdy, retractable legs forming an “A” shape, made from wood, plastic, or metal. Their foldable design makes them easy to deploy, store, and transport. Commonly used for pedestrian control, car park guidance, and road closures, they effectively delineate restricted areas and guide traffic flow.
Permanent Barriers
- Concrete barriers, made from reinforced concrete, are durable structures designed to prevent vehicle crossover accidents, protect pedestrians, and delineate traffic lanes. They offer high impact resistance, require minimal maintenance, and are commonly used on highways, medians, construction sites, and bridges for safety and traffic separation.
- Guardrails are safety barriers made from steel or high-tension cables designed to prevent vehicles from veering off the road, especially in hazardous areas like curves, slopes, and bridges. These steel barriers enhance road safety by keeping vehicles on the roadway.
- Bollards are short, sturdy posts designed to block vehicle access while allowing pedestrian movement. Made from materials like steel, concrete, and plastic, they protect buildings and pedestrians, guide traffic, restrict vehicle access, and enhance security.
- Crash cushions absorb and dissipate collision energy, reducing crash severity and protecting motorists and structures. They minimise damage, enhance safety, and are easy to install and replace.
- Cable barriers, made of high-tension steel cables mounted on posts, prevent vehicle crossovers and reduce crash severity. Their flexibility absorbs crash energy, effectively preventing head-on collisions and minimising vehicle damage. They are cost-effective and commonly used on highway medians, curves, and high-risk areas.
Specialised Barriers
- Noise barriers are essential for reducing traffic noise in surrounding communities, particularly near busy highways. Constructed from various materials like concrete, metal, and vegetation, these barriers block or mitigate sound waves, significantly lowering noise levels in residential and sensitive areas. Proper design can reduce noise pollution by 10–15 decibels, improving the liveability for nearby residents.
- Median barriers prevent vehicles from crossing into oncoming traffic, reducing head-on collisions and enhancing road safety. They are low maintenance, durable, and commonly used in high-speed traffic areas and highways to keep vehicles in their designated lanes.
- Bridge barriers are crucial for the safety of vehicles and pedestrians, designed to withstand high impacts and prevent accidents. Made from materials like reinforced concrete, steel, and composites, these barriers balance strength, durability, and aesthetics. They integrate into bridge structures, often including railings for added pedestrian safety. By absorbing impacts, they protect the bridge’s structural integrity and prevent severe accidents.
Choosing the Right Barrier for Specific Needs
When choosing a road barrier, consider traffic type, speed limit, location, safety needs, and budget. Temporary barriers suit short-term projects, while permanent ones provide long-term solutions. Specialised traffic barriers address specific needs like noise control and bridge safety.
