‘Crash Cushion’ Temporarily Installed in Scotland Undergoes Testing

The very first so-called ‘crash cushion’ which was installed in Scotland on a temporary basis has already gone through a test on a project to develop a new junction along Scotland’s M8.

The CTM Group was the company which installed the crash cushion, called Tau Tube, produced by Highway Care, to serve as a fitting end terminal to a steel barrier erected temporarily on the rib line of the M8’s lane 1. The crash cushion was part of the project involved in constructing the Bishopton Interchange. 

The Tau Tube’s importance and inherent functionality 

The crash cushion served an important function as additional temporary protection which was necessary for a section which remained unlit on the motorway, and this section had no existing restriction on speed either. 

The crash cushion installation was the very first type of crash cushion barrier in Scotland, and this barrier was also sourced by the firm Morgan Sindall (costing £14.1 million) after it consulted with Police Scotland and Transerv. 

According to the commercial manager of Highway Care, Mr. Ian Davey, the group has been successfully making use of these crash cushions around different parts of England, which function as safe end terminals for TVRS, or Temporary Vehicle Restraint Systems, which also include barriers made from concrete and steel. Mr. Davey adds that due to its re-directive functionality and performance, these crash cushions have saved numerous lives – not just the lives of drivers, but also the lives of road workers - in the last few years.

Mr. Davey goes on to say that they are pleased with their partnership and collaboration with the CTM Group when it comes to the installation of the cushions, and through this partnership, they have been able to provide 10 kilometres of their BarrierGuard 800 barriers as well as enhance access to various solutions for safety which are not yet deployed in Scotland. 

The Tau Tube is able to take impact of as much as 110 kilometres per hour in less than six metres. In addition, the Tau Tube system does not require as much space and has fewer parts and requirements for maintenance. The system is also entirely suitable for locations which are narrower, serving as a cushion which re-directs road users in order to protect different hazards such as toll booths, bridge parapets, and highway nosings which may not be easy to relocate or remove.

The testing of the Tau Tube system 

The Tau Tube cushion placed along the project at the Bishopton Interchange was tested in a collision, and it was able to re-direct the wayward vehicle in a safe manner and perform according to expectations. The cushion was then promptly and conveniently replaced so the project can continue without any other incidents.
