WDM® operates a fleet of survey vehicles to provide safe, reliable and cost effective assessment of road conditions.
WDM® systems link road condition data with accidents, structures, customer services, inventory, road maintenance and other data.
Equipment and Manufacturing
WDM® expertise is widely recognised in the field of pavement, road and highway survey equipment design.
The WDM® consultancy service was developed to help clients maximise the use of survey data.
Keeping cyclists safer with Cyclopath
Bristol-based engineering company, W.D.M. Limited, has called on its unrivalled experience of testing the surfaces of UK roads to develop a specialist machine to check the safety of cycle ways. The Cyclopath uses tried and tested laser technology to scan the surface of cycle paths to check for rutting, texture depth, changes in the transverse profile and any cracking. It has just successfully completed more than six months of trials in the West Country and in London. The National Cycle Network was developed by the charity Sustrans, which was launched in Bristol in the 70’s, and covers 14,000...
Pothole Scanning Solution
Specially adapted Road Assessment Vehicles (RAVs) from WDM® are using laser beams to record defects on roads throughout the UK – and identify early signs of potholes. W.D.M. Limited, the UK’s largest road condition surveying company, has been using the technology to identify surface cracking since the Millennium. If left unrepaired, it can lead to potholes! Essex County Council has been using RAVs to show that the condition of its roads improved for the third year in a row in 2014. The data collected is used to prioritise maintenance work by highways engineers....
Saving Lives Through Safer Roads
WDM® has been surveying the road network annually in New Zealand since 1995, helping deliver remarkable reductions in road casualty rates and resulting in further developments of its SCRIM vehicle through the addition of the latest ITS programming. Skid resistance of road surfaces is one of the primary factors that determine the safety of roads and the wet skid injury crash rate on road sections with “low” skid resistance is 4.5 to 9 times greater than that for all roads. Results of crash site analysis indicate that a 0.1 increase in skid resistance (measured in terms of Mean Summer...
WDM® SCRIM in America
Researchers at Virginia Tech Transportation Institute (VTTI) in America are evaluating the safety of highway surfaces in several US states using British technology. The Federal Highways Administration is funding a project to analyse continuous stretches of pavement in six US states to determine whether improving highway materials or design could reduce crashes and save lives. They’re using the Sideway-force Coefficient Routine Investigation Machine (SCRIM), from W.D.M. Limited, based in Bristol, UK. The data collection phase started in Washington and will include testing in Florida, Indiana and Texas. More than 32,000 people die annually on America’s...
Roads for a modern Britain
The UK’s roads sector is at the start of a major transition with the government promising record levels of investment on the basis that the industry will deliver better value for money together with improved quality and a safer network. It’s against this background that the second Highways UK event will take place at the NEC in Birmingham on 16-17 November 2016 – and WDM® will be there exhibiting. WDM® will be meeting key decision makers and stakeholders, including highway engineers, civil engineering consultants, contractors, transport planners and suppliers,...
