Mobile Access Protection for Events

These systems are intended to force approaching vehicles to reduce their speed. However, their effectiveness is limited if there is sufficient space for a vehicle to accelerate again after bypassing the obstacle – a tragic reality observed during the incident in Volkmarsen (D).

Furthermore, the quantity of barrier elements used is a decisive factor. As a general rule: the fewer the elements, the lower the protective effect and the greater the penetration depth. When evaluating a system, you should always ask the manufacturer for the following technical evidence:

• The exact number of elements used during the actual crash test or certification

• The specific penetration depth (displacement) that was achieved under those test conditions

Using large vehicles as makeshift protection is common but lacks certified reliability. Crash simulations show that these HVM solutions are often pushed aside at high speed. Key risks include:

• Displacement: Failure to stop a vehicle, pushing the barrier into the crowd

• Operational Risks: Blocking sightlines and obstructing emergency evacuation routes

Non–certified concrete blocks typically fail as Hostile Vehicle Mitigation and can become dangerous projectiles. To function as effective barrier systems, elements must be specifically engineered. For professional protection, ensure:

• Concrete elements are securely connected via a certified linking system

• Kinetic energy is distributed across the entire access protection line

In many major cities, they have become a staple of the urban landscape: flowerpots, benches, and large planters anchored firmly into the ground. These elements provide “invisible” protection and are highly regarded by both urban planners and the public alike. To meet these diverse needs, various suppliers produce a wide range of street furniture for mobile access protection:

• Fixed Installations: Permanently anchored for long–term security

• Removable Solutions: Flexible elements for multi–use public spaces

However, it remains essential to ensure that such furniture is specifically engineered and tested to withstand impact loads as HVM systems, as standard decorative items often lack the structural integrity required for a professional security concept.
