Connected and autonomous (CAV) vehicle project could end motorway pileups

A pioneering connected and autonomous vehicles project has developed technology that could radically reduce the number of multi-vehicle collisions on motorways. The Multi-Car Collision Avoidance (MuCCA) research and development project, has used artificial intelligence (AI) and vehicle-to-vehicle (V2V) communications to instruct autonomous vehicles to cooperatively make decisions to avoid potential incidents.

The project, funded by Innovate UK and the Centre for Connected and Autonomous Vehicles (CCAV), and delivered by a consortium led by Applus IDIADA with Cranfield UniversityWestfield Sports CarsCosworthSBD Automotive and Connected Places Catapult, has seen MuCCA equipped vehicles successfully complete replicas of real-life UK motorway scenarios on test tracks.

When the technology in the vehicles detects an incident, the cars share information by radio links, and the onboard computers calculate the best manoeuvres to avoid the obstacles and then safely steer the agreed path to avoid an accident. The MuCCA equipped vehicles also avoid each other and remove the need to brake suddenly – which may have caused vehicles behind to drive into them.

Connected and autonomous vehicles (CAVs) are expected to become increasingly common on our roads within the next 10 years, there will however be many non-autonomous ‘human-driven’ vehicles that will remain for the foreseeable future. In this near-future scenario, MuCCA equipped vehicles could take on the added complexity of anticipating the likely behaviour of any human drivers in the vicinity of an incident.

Although the UK has some of the safest roads in the world, around 4,500 accidents still happen on UK motorways each year, contributing to 1,700 annual deaths and over 22,000 serious injuries. Incidents on the motorway network also cause delays and congestion which can have a serious economic impact on UK businesses, costing around £8 billion a year according to estimates. MuCCA technology in connected and autonomous vehicles has the potential to significantly reduce these.

Rachel Maclean MP, Parliamentary Under-Secretary (Department for Transport) said: “The potential of self-driving vehicle technology is unprecedented and could help to level up transport across the nation by making everyday journeys greener, safer, more flexible and more reliable.
The MuCCA project is yet further proof of the UK leading the way in the safe and secure development of self-driving vehicle technology.”

Charlie Wartnaby, Technical Lead, Applus IDIADA UK said: “The MuCCA project has delivered a world-first, achieving collective collision avoidance behaviour between real cars, in a clear demonstration of fully automated cooperative control mediated by vehicle-to-vehicle radio. Combining connectivity and automated driving like this has applications beyond the valuable emergency role proven here to more general cooperative vehicle movement, promising enhanced safety and efficiency on our roads in future. This places the UK at the commercial forefront of driving technology that will benefit all of society.”

Nicola Yates OBE, Connected Places Catapult CEO said: “The MuCCA project has realised one of the most talked-about aspects of connected and automated vehicle technology, safety. Connected Places Catapult is proud to have used our extensive experience with autonomous technology, to support the world-leading consortium incorporating large organisations, SMEs and academia, to develop a ground-breaking system and establish the UK as a global leader of vehicle-to-vehicle connected safety solutions.”

Guillermo Tejera, Lead Project Manager and Senior Engineer, Applus IDIADA said: “From concept definition to the final trials and demonstrations, the MuCCA project has successfully combined the joint effort of an outstanding consortium to develop a next-generation driver aid. After two and a half years of development and testing, a genuine concept that integrates the latest technologies has proven the principle of reducing car accidents using automated and leaderless cooperation between vehicles.”

Ross Walker, Research Fellow/Engineer in Autonomous Cars in the Signals and Autonomy Group in the Centre for Electronic Warfare Information and Cyber at Cranfield University, said: “The scope of MuCCA is vital for safe future transportation systems and so we’re thrilled to be part of the project. The University is a pioneer in connected and autonomous vehicle engineering, and we were able to develop computer algorithms that help the cars to react in a more human-like way when avoiding collisions. This can allow any potential accidents to be recognised in advance, and consequently avoided before they have the chance to begin developing.”

Icaro Bezerra-Viana, Research Fellow in Autonomous Cars in the Signals and Autonomy Group in the Centre for Electronic Warfare Information and Cyber at Cranfield University, said: “Computer simulations enabled us to model how human drivers behave on motorways, and how the proximity of surrounding cars influences their behaviour. The movement of the cars that surround a vehicle over the next few seconds can then be predicted in order to avoid a collision. Being part of the MuCCA consortium and working with partners has enabled us to learn more techniques and work together to find the most appropriate solutions.”

Tom Buckler, Managing Director, Cosworth Electronics said: “We are proud to be a partner in the pioneering MuCCA project, which has provided the opportunity for Cosworth to extend our advanced electronics and data analytics technologies into the LiDAR and machine vision systems space for autonomous vehicles. It is great to see how the project has come together to lay out the roadmap for the future of mobility.”

Julian Turner, CEO, Westfield Sports Cars said: ‘The MuCCA project provides a unique perspective into the importance of emerging technologies, such as vehicle to vehicle communication, role in the future of Connected Autonomous Vehicles motorway deployments.’’

Luigi Bisbiglia, Business Development Manager, SBD Automotive said: “In a project like MuCCA, it is important to think about the cyber threats. For example, how to prevent malicious spoofing interfering with vehicle controls, whilst allowing genuine co-operating “stranger” vehicles to influence control. SBD identified the “bad actors” who may have an interest in attacking V2X systems, and the elements of the system they might try to attack, allowing us to propose a number of cyber security features that will make the system more secure. As experts in connected and autonomous vehicles, our involvement in MuCCA allows us to further differentiate our services from the mass market of generic pen testing companies.
