Safe and secure solutions
Solutions to stop heavy vehicles driven at high speed have long existed but they are mainly emergency measures which can be rapidly deployed but are impractical in aesthetic and functional terms: concrete blocks, planters, Jersey Barriers and low concrete walls are all able to secure access points effectively but they're difficult to install and move and they often detract from the aesthetic appeal of the protected sites.
Issues with solutions of this type:
• if rammed by a truck travelling at more than 30 mph, conventional barriers will slow the vehicle, but could still be displaced beyond the point of impact and may still strike any persons present in the immediate vicinity;
• after installation, they can no longer be moved without the use of a crane and specialised personnel, resulting in higher costs and more time;
• blocking off vehicular access, with these solutions could also prevent the transit of emergency vehicles (ambulances, fire engines and police vehicles);
• their appearance could impair the aesthetic appeal of the sites where they are installed.
