Yotta to Survey West Midlands
Yotta to survey West Midlands highways with new hi-tech road surface scanner
The consortium of West Midlands Local Authorities has awarded Yotta DCL the contract for road condition surveying using the latest vehicle-based technology across the region’s network. The SCANNER surveys were procured on behalf of the consortium by Solihull Metropolitan Borough Council. The highway technology and surveying company will use its new Tempest survey vehicle to capture road surface condition and forward facing video, plus pavement images at normal traffic speeds.
Yotta DCL will survey a total of 1250 km of A, B and C roads under the terms of the contract, which could be extended by three years. By providing both SCANNER and forward facing video and pavement images, the Authorities will be able to cross reference road condition data against high quality images. The camera technology onboard the new Tempest vehicle is a major advance in quality, breaks new ground in high definition video, and is unique to Yotta DCL.
“Yotta DCL has always provided quality data and from our previous experiences of working with the company over the past eight years we know that it provides a very reliable survey service meeting all the consortiums timescales and requirements. By overlaying the SCANNER data onto the video we can get a real life view of the data. The ability to cross reference the data against the video helps to guide our decision making as we can actually see the condition of the road surface on screen,” says Paul Price, Senior Engineer, Solihull Metropolitan Borough Council.
Tempest is designed and built exclusively by Yotta DCL and is accredited by TRL (the UK’s independent and official Transport Research Laboratory) for UK SCANNER and TRACS (Traffic Speed Condition Survey) specifications. It has been developed using new processing technologies to improve accuracy and the vehicles are equipped with forward facing cameras which can be used to provide street level imagery. Cracking data is processed from high-resolution images of the pavement taken by a line scanning camera. The video images can be further utilised using Yotta DCL’s Horizons web based highway asset Management system to obtain width measurements for pavement inventory and defend insurance claims. As the survey is captured every year it is useful to have a date and time stamp of the network and the condition at that point in time.
