Talk:Concrete step barrier

Why are they asymetrical? What is the purpose of the below the ground section and why is it not on both sides? Are these safer for motorcycles? 92.232.36.159 (talk) 15:17, 31 October 2008 (UTC)[reply]

The below ground section you refer to is actually a drainage channel. It only needs to be on one side of the barrier, depending on the elevation and camber of the road. Williamstroker (talk) 18:41, 21 December 2008 (UTC)[reply]

Advertisment?

There seems to be an incredible amount of very positive information here added by user Pushcreativity. Interestingly this is the only article Pushcreativity has edited or linked to. Also an image by a company called Britpave has been uploaded here by Pushcreativity. Britpave manufacture and install concrete step barriers, even maintaining a website http://www.concretebarrier.org.uk/ to advertise this. The website was built by a marketing company called Push Creativity (website http://www.push.uk.net/). Rubensni (talk) 23:32, 14 January 2009 (UTC)[reply]

UK Change of Policy

Were any reasons given for the change of policy in the UK dictating that all new motorway medians will be concrete instead of steel? What are the advantages (cost, safety) of using each system? 92.41.251.136 (talk) 19:18, 22 January 2010 (UTC)[reply]

I don't know the DfT's reasons for its decision. However, it coincided with the The Federation of European Motorcyclists Associations (FEMA) publishing a report identifying concrete barriers as significantly safer than steel. If the barrier is smooth concrete, impact is spread over a relatively wide surface. Many collisions with a safety barrier are at a relatively shallow angle, in which case a casualty can then slide along the barrier in the direction of travel, dissipating momentum and coming to rest relatively intact.

Conventional W-section steel barriers have support posts that severely injure any casualty who is not protected by a vehicle. This can include anyone thrown out of a vehicle as well as motorcyclists. Concrete barriers are also safer than Wire Rope Safety barriers, which combine hazardous support posts with tensioned steel cables that can also cause severe injuries.

Also in 2005 the Department for Transport (DfT) published The Government's Motorcycling Strategy and the Institute of Highway Incorporated Engineers (IHIE) published Guidelines for Motorcycling, both of which included sections on reducing roadside casualties. FEMA's 2005 report can be downloaded from its website: [1]. Motacilla (talk) 01:15, 23 January 2010 (UTC)[reply]
