Studies have shown that utility trenching can have a detrimental effect on both the surface condition and the underlying structure of highways, thereby shortening their service lives. In the UK, there ...

For the last ten years an annual correlation trial for Falling Weight Deflectometers (FWDs) has been held in the UK. The objective of the trial is to assess the performance of all FWDs (including ...

TRL is partnering with University Hospital Southampton to reduce road deaths by linking health records and road traffic collision data for the first time. The partners have been awarded £500,000 in ...

TRL has produced a technical research paper commissioned by the Department for Transport (DfT) to support the development of regulations for e-scooters in the UK. The report, co-authored by WMG at the ...

In transport, too, the power of the healthy choice is over-rated. For most of human history, for most people, the only way to get around was to walk. Evolution delivers the most efficient and ...

In Many countries road traffic is growing rapidly in volume and in size and weight of the vehicles using the roads. As a consequence, highway engineers concerned with designing new roads or the ...

This guide provides engineers with methods of repairing road haunches by re-using road materials or industrial by-products. The guidance given is based on the in-service performance of re-usable ...

Understanding the relationships between road surface properties and high speed friction is key to managing the risk of loss of vehicle control. It is understood that, in wet conditions, texture depth ...

Road surface friction on the Strategic Road Network (SRN) is managed through the requirement to provide skid resistance and texture depth. The requirements have been in place since the 1980s and were ...

RAC Foundation (2008) reported the results of a survey of 2,000+ users of Facebook, showing that 45% of UK drivers engage in texting whilst driving. The RAC Foundation commissioned TRL to study the ...
