Imagine a future where cars can “talk” to one another to avoid accidents and figure out who has the right of way at junctions. You’d be able to get into your car, give it a location and then rest as it automatically sends you to your destination.
Nanyang Technological University (NTU), its School of Electrical and Electronic Engineering (EEE) and Dutch firm NXP Semiconductors have joined forces to help make this a reality. They have set up a four-year, S$22 million programme to study vehicle-to-everything (V2X) technologies that enable vehicles to communicate wirelessly with one another and with intelligent roadside infrastructure such as traffic lights.
Cars, motorcycles and other automobiles would get real-time alerts about road conditions and other vehicles, including their speeds and directions, long before dangers come into sight. According to the United States Department of Transportation, V2X safety functions could have prevented more than 80 percent of multi-car accidents. NXP Executive VP of Technology & Operations, Dr Hai Wang said: “More roads, tunnels and overpasses will not solve global megacities’ traffic challenges in the long run Technologies like V2X can save lives by avoiding accidents and limiting congestion, travel time and carbon dioxide emissions."
The NTU-NXP test bed will involve more than 100 vehicles and 50 roadside units in the NTU campus. The researchers have installed some of the infrastructure and successfully tested several applications including accident and pedestrian crossing warnings.
They are now working on areas such as car convoying, where cars follow one another in a tight formation to optimise traffic flow, and protecting the Internet-connected vehicles against hackers.
"The rapid growth in vehicle populations needs to be matched by an efficient, safer and clean transportation system. Our collaboration will also pave the way to realising Singapore’s Smart Mobility 2030 vision.”
Professor Peter Chong, Director of the NTU-NXP Smart Mobility Test bed.
