USP researchers say future cars will communicate to avoid collisions

Two researchers at The University of the South Pacific’s, School of Computing, Information and Mathematical Sciences have developed a set of algorithms that will enable robotic cars to communicate with each and avoid collisions.

Researchers Dr Bhibhya Sharma and Dr Utesh Chand presented at the 1st Rim Mathematical Association (PRIMA) conference in Sydney last week.

Dr Sharma who supervised the research said that the series of mathematical equations would instruct robotic cars when and how to merge lanes, which could lead to less accidents and ease traffic congestions.

According to Sharma, flocking is a biologically inspired technique and a strategy commonly used in robotics. "One of the advantages of flocking is that robots can work together and achieve what would take individuals far longer", he said.

He further explained that each car will be controlled by a centralized brain guided by a series of algorithms to control the car. The brains will talk to each other and instruct the cars to merge lanes and move in formation together.The team demonstrated the technique using computer simulation and is currently trialing it in two wheel robots.

Fellow researcher, Dr Chand says that the cars have targets they move towards and maintain and when the cars find themselves in a merging situation, one of them will be given the position of leader, the rest will follow.

The team has written equations for attraction towards the target, enabling cars to stay inside their lanes and avoid crashing into each other. The challenge now is to allow the robot to automatically plan how to avoid crashing with the side of the road and cars travelling close by.
