With regard to the A83 Rest and Be Thankful you asked "Can you tell me what the speed rating (or manufacturers recommended speed) for the speed humps that have been deployed in the road works at the RABT.
If they are designed to slow traffic to significantly lower speeds than 30mph, what risk assessments have been conducted on the impact of repeated use on road users suspension?"
As the information you have requested is 'environmental information' for the purposes of the Environmental Information (Scotland) Regulations 2004 (EIRs), we are required to deal with your request under those Regulations. We are applying the exemption at section 39(2) of the Freedom of Information (Scotland) Act 2002 (FOISA), so that we do not also have to deal with your request under FOISA.
This exemption is subject to the 'public interest test'. Therefore, taking account of all the circumstances of this case, we have considered if the public interest in disclosing the information outweighs the public interest in applying the exemption. We have found that, on balance, the public interest lies in favour of upholding the exemption, because there is no public interest in dealing with the same request under two different regimes. This is essentially a technical point and has no material effect on the outcome of your request.
- Can you tell me what the speed rating (or manufacturers recommended speed) for the speed humps that have been deployed in the road works at the RABT.
The rumble strips deployed on the A83 at Rest and Be Thankful are in place to provide enhanced warning of the presence of the works site and to aid the management of vehicle speeds through the extent of traffic management. The strips are recommended for vehicle speeds up to 70mph but have been successfully tested at speeds in-excess of the maximum national speed limit.
- If they are designed to slow traffic to significantly lower speeds than 30mph, what risk assessments have been conducted on the impact of repeated use on road users suspension?
The strips are not in place to slow traffic to below 30mph but more to act as a reminder of the enforced speed limit and the approaching or adjacent works site. The low profile of these strips does not require any specific testing or assessments for impact on vehicle suspension but is sufficient to offer the enhanced messaging for which they are deployed at A83 Rest and be Thankful and other work sites around the UK.
