4th Safer Roads Conference 2014


WDM® is helping organise the 4th International Safer Roads Conference, which will be held in the UK from 18 - 21 May 2014 with the overriding theme of "saving lives through safer roads”.

Every six seconds someone is killed or seriously injured on the world's roads resulting in 1.3 million road deaths each year. Whist there is growing awareness of the important role developing nations have to play in averting the emerging disaster of road accident rates, developed nations cannot be complacent.

In the UK almost 2,000 lives are lost on the roads every year and 2011 saw the first increase in road deaths for nearly a decade, making the Conference theme even more relevant.

The 4th Conference is being organised by WDM® in conjunction with the New Zealand Transport Agency and the Chartered Institute of Highways and Transportation and will support the UN Decade of Action, launched in 2011, to emphasise the importance of the road surface as well as other road safety initiatives in reducing accident rates.

Delegates will consist of engineers, practitioners, policy makers and other professionals from central and local governments, academics from universities and research organisations, consultants and contractors.

For further information and to view papers from the first three conferences visit the 2014 conference website

Roads to Success


The Daily Telegraph Business Club has commissioned an independent film profile of W.D.M. Limited, its approach as a company, how it’s evolved and developed and the factors behind its success. From its beginnings more than five decades ago W.D.M. Limited has focused its attention on listening closely and responding to the needs of its customers. It’s a simple formula, but one that is all too often overlooked as companies evolve and expand. Today the business specialises in designing equipment to monitor highways and pavements and to assess their maintenance needs.

W.D.M. Limited is widely recognised as a leader in its sector, providing services to most UK local authorities, and has reached this position by working closely with its clients to provide equipment and services that are genuinely invaluable. The Daily Telegraph film charts the company’s development and explains how it is working hard to develop the same close relationships with road engineers across the globe. Click here to view.




The TM2 brochure is available in various languages, use a flag to download your prefered choice:-

The updated TM2 surface texture meter with the latest electronics is the result of an extensive in-house research and development programme by WDM® to provide all the functionality of a routine texture measurement instrument, coupled with extensive analysis tools.

The TM2 is recognized as delivering the definitive macro texture measurement standard. The updated TM2 measures a broad swathe of the road profile transversely over a width of 100mm at very frequent intervals to build a detailed record of the surface, with its average texture depth, and delivers repeatable and consistent results.

It is widely recognised that pavement texture is an extremely important factor in the control of surface friction and subsequent road safety. It is also an important parameter for the determination of factors such as noise emission from vehicle tyres.

SCRIM at Intertraffic Amsterdam

One of W.D.M. Limited’s newest mini-SCRIMs will be taking centre stage at Intertraffic Amsterdam.

The Company will be exhibiting at the Amsterdam RAI for the second time after making their show debut in 2012. The mini SCRIM, which was designed to operate in towns and cities and on narrower roads, will be the main attraction on stand number 338 in Hall 5.

In addition to showing the SCRIM, WDM® will be demonstrating the TM2 texture meter, which was previously nominated for an Intertraffic innovation award. The manually operated machine measures the macro texture of the road’s surface and is designed to replace the sand patch method.

Intertraffic Amsterdam 2014 will take place from 25 - 28 March 2014 in Amsterdam RAI, and will extend over 10 halls, featuring the latest innovations and technologies on ITS traffic management, parking, safety and infrastructure.
