Bollard and Safety Barrier Solutions

Bollard and Road Blocker

A bollard is a short, vertical post installed in the ground to control, guide, or block vehicle traffic while still allowing pedestrians and smaller vehicles (such as bicycles or emergency‑service vehicles) to pass. A road blocker, in contrast, is a robust, full‑width barrier that rises from the pavement to physically prevent any vehicle from passing through the roadway. Together, bollard and road blocker systems form complementary layers of hostile‑vehicle‑mitigation (HVM) and access‑control infrastructure at secure sites.

Bollard and Road Blocker – Key Differences

A bollard and road blocker differ mainly in size, footprint, and impact resistance.

• A bollard is compact: typically 200–275 mm in diameter, with a height of 600–1,200 mm, and is often installed in a line across the roadway. Bollards can be fixed, removable, semi‑automatic, or fully automatic, and crash‑tested versions can stop cars and light trucks in low‑ to mid‑level security applications.

• A road blocker is a full‑height, heavy‑duty barrier that spans the entire lane or multiple lanes. It rises from a shallow or deep foundation pit and is engineered to withstand high‑speed, high‑mass collisions (often rated to PAS68, IWA14‑1, or ASTM F2656 M30/M50 standards), making it suitable for high‑risk facilities such as government compounds, military bases, airports, and critical infrastructure.

Bollard and Road Blocker – Functions and Applications

The bollard and road blocker concept is used to create tiered access control:

• Bollard systems are ideal for car‑oriented exclusion, guiding traffic, and protecting pedestrian zones, such as:

  • Perimeter fencing at office parks, residential compounds, and shopping malls.

  • Drop‑off zones, hotel entrances, and mixed‑use urban streetscapes.

  • Low‑ to medium‑risk entrance control where aesthetics and space efficiency matter.

• Road blocker systems are deployed where the highest level of anti‑ram and antiterrorist protection is required, such as:

  • Service entrances, perimeter gates, and guarded access points at embassies or military bases.

  • Runway‑adjacent zones, cargo‑handling areas, and air‑controllers’ entrances at airports.

  • Critical energy, data‑center, and industrial‑facility gateways.

Bollard and Road Blocker – Operation and Integration

Both bollard and road blocker units can be automatic (hydraulic or electromechanical) or manual, and they integrate with access‑control systems, CCTV, ANPR cameras, and emergency‑alarm networks. In many high‑security layouts, an entrance will combine:

• A first line of automatic bollards for normal‑day traffic and low‑impact deterrence.

• A second, deeper line of road blocker for full‑HVM protection, activated only when required by security protocols or threat levels.

This bollard and road blocker strategy balances day‑to‑day operational flexibility with maximum protection against hostile‑vehicle attacks, giving facility managers and integrators a scalable, standards‑compliant solution for vehicle‑barrier design.
