The two companies are together developing and testing various concepts and prototypes in the ‘Safer@Work’ research project. For example, they recently tested a people detection system at two Colas sites in Switzerland: an asphalt plant and a quarry. The system uses artificial intelligence (AI) to alert the operator when a person is detected in the vicinity of the machine. It incorporates different warning systems, both for the operator and for people in the area surrounding the machine.
Volvo engineers were already developing the integrated AI algorithm and it was further improved during the Safer@Work project. The prototype is one of three operator assist concepts that Volvo CE has been collaborating on with Colas since 2016. They are now at the stage of assessing viability for the industry. Plans to industrialise it under investigation.
“Safety is one of Volvo CE’s core values and we are actively working to create even safer work sites for employees, customers and anyone in the vicinity of our machines,” says Volvo chief project manager Veit Kleeberg. “When Colas approached us to partner on this research project we were keen to get involved. We used the ‘design yhinking’ methodology – which involves putting the user first and finding out their needs before generating ideas – and came up with 27 concepts that could contribute to reducing the number of accidents involving employees and members of the public on construction sites. Together with Colas, we picked the three preferred concepts and we started to design and test them.”
Volvo has now carried out tests on excavators, wheeled loaders and articulated haulers at Colas job sites. The people detection concept was tested on a EW160E excavator and a L220H wheel loader.
“The testing was a great success and the operator feedback was very encouraging,” says Veit Kleeberg. “This time we were focusing on the accuracy of the concept, after we’d made some improvements following tests with Colas in January. Being able to test the technology in a real-world environment and getting instant customer feedback is invaluable. This partnership has enabled us to investigate new technologies and explore concepts that add value for our customers and address our ambitions such as zero accidents.”
Colas safety director Philippe Simarik says: “We wanted to partner with a construction equipment manufacturer and create an innovative safety system that would reduce the number of accidents involving people on construction sites.
“Given that we share core values, especially safety, Volvo CE was the ideal choice. We are working together to develop and test various new ideas. The most mature of those ideas is the people detection concept, and we hope to equip our machines with this system in the future. Our collaboration with Volvo CE has been extremely positive. Together we have come up with a solution that will improve work site safety.”
