Crash cushions are mounted to the rear of motorway maintenance vehicles. As the
name suggests, the crash cushion is designed to offer protection in the
event of high speed collisions from approaching traffic.
The cushion will offer protection to:
Workers in front of the impacted maintenance vehicle.
The occupants of the impacting vehicle.
The maintenance vehicle itself.
SmartStop has not only been designed with saving lives in mind, practicality is
The SmartStop’s collapsible frame
is multifunctional providing controlled crush and significant structural
rigidity during everyday use.
The optimum weight to performance ratio of
has been exploited in many scenarios. The
total cushion weight is only 300kg, minimising the load to the works
The support frame
is designed to easily withstand the movements of the crash cushion in its
lowered position. Whilst developing the crash cushion, our calculations allowed for large amplitude vibrations and
motion, which exceeded the basic requirements.
The support frame
has been designed and tested to withstand multiple impacts, making the cushion reusable.
The SmartStop is designed from a series of modular components
for allowing partial replacement and repair in case of damage.
The design has seen the involvement of approximately 20 multi-disciplined
engineers, two world class test houses, research institutes, and of course
SmartStop has evolved through design, optimisation and evaluation using 3D CAD,
and Virtual Finite Element Analysis, prototype testing in Euro Road Safety’s own
test laboratories, and full scale testing.
SmartStop has been developed in accordance with the demanding US NCHRP350 and UK
The device is fundamentally designed to provide crash mitigation offering:
