By virtually eliminating crossover incidents, the step barrier will save millions of pounds in accident recovery costs and insurance claims. Even following severe impacts, the barrier is undamaged and requires no repair. CostĬSB is completely maintenance-free, saving clients and taxpayers tens of millions of pounds every year. This better service to users is at the heart of Highways England corporate policy. This means that all road users will be able to plan ahead and predict journey times with more confidence and accuracy. With almost no maintenance requirements, no lane closures and no associated delays, concrete step barrier delivers greater journey reliability. To put this into perspective, at the time that CSB was adopted the then Highways Agency Area 5, which includes the M25 and associated link roads, carried out hundreds of repairs to steel barrier every month at an average cost of around £5M per annum. This means there is often no need to report minor impacts or close off adjacent lanes to carry out repairs. This also increases safety for repair teams who are currently at risk working alongside dangerous moving traffic.Ĭoncrete step barrier requires minimal maintenance and repair throughout its minimum 50-year life as it suffers negligible damage if struck by a vehicle. As concrete step barrier requires no maintenance, the need for lane closures is reduced significantly. Importantly, accidents to workers and to vehicles in road works should also be reduced. With injuries predicted for CSB being very much lower than set limits, injuries resulting from an impact with CSB are very unlikely to be serious. #CONCRETE BARRIER LUMENRT TEMPLATE SERIES#In crash simulation tests, for instance, a series of measurements are taken from a EuroSID dummy and compared to limits set out in ECE Regulation 95 for Lateral Collision Protection. Results from both crash testing and computer simulations – undertaken by the Vehicle Design Group at Arup, one of the world's leading consulting engineers – confirm CSB’s excellent safety credentials. Vehicle crash tests approved by the then government's Highways Agency (now Highways England) demonstrate that it can successfully contain all vehicles including 4x4s, pickup trucks and light vans up to 13.5 tonnes, which includes most buses and coaches. Such slight impact will, in most cases, allow the vehicle to continue on its journey undamaged. Step barrier is specifically designed to limit minor vehicle contact to the base of the barrier and the vehicle tyres. SafetyĮxperience in other countries and 10 years of use along the M25 in the UK has proved that concrete barrier is safer than competing systems. CSB provides high-level H2 containment with a reduced ASI value of only 1.4 and impact severity level B, which easily meets BS EN1317 requirements. When crash tested, it is important that Acceleration Severity Index (ASI) values meet EN 1317 requirements so that the system used cannot be considered to pose an excessive risk to the occupant of the vehicle hitting the barrier. Appropriate containment levels are determined by Government policy and are related to numerous criteria including (but not limited to) the type of road, volume of vehicles and structures being protected. Benefits High containmentĬSB inherently provides high containment at no additional cost, delivering a safe environment for motorists. The extensive Smart Motorway programme of works by Highways England has Concrete Step Barrier as a key element. All existing motorways will introduce concrete barriers into the central reserve as part of ongoing upgrades and through replacement as and when existing systems have reached the end of their useful life. #CONCRETE BARRIER LUMENRT TEMPLATE MANUAL#With effect from January 2005, and based primarily on safety and cost grounds, the Agency’s policy, as detailed in Volume 2 of its Design Manual for Roads and Bridges is that all new motorway schemes are to use high containment concrete barriers (namely CSB) in the central reserve. The use of high containment concrete barriers in the central reserve on highly trafficked motorways is one initiative that helps meet these aims. Highways England continuously aims to improve safety and congestion, as well as reduce costs and improve reliability. CSB has a unique stepped profile that has been shown, through testing and computer simulation, to help reduce injury to occupants of small cars by limiting contact to the base of the barrier and the vehicles’ tyres. Tested extensively to the requirements of the European Safety barrier standard EN 1317, CSB has the ability to contain errant 4x4s, light vans and trucks up to 13.5 tonnes, including most buses and coaches. #CONCRETE BARRIER LUMENRT TEMPLATE FREE#Concrete Step Barrier (CSB) is a vehicle restraint system designed to contain vehicles, save lives, reduce congestion and be maintenance free for at least 50 years.
