Drivers are alerted to safety confl icts by C-V2X
RE SAFETY IS 5G A IN WAITING? A
round 1.35 million people die annually as a result of road traff ic crashes. More than half of these
deaths are vulnerable road users – pedestrians, cyclists and motorcyclists – and it is the leading cause of death for children and young adults aged 5-29 years. Advanced driver assistance systems
(ADAS) have come on in leaps and bounds during recent years to help improve road safety, but 5G and increased cellular vehicle-to- everything (C-V2X) connectivity will enable new technologies with life- saving potential to come to market. Samsung’s Harman has introduced
‘vehicle-to-pedestrian’ technology that utilises low latency 5G peer-to-peer signals and proximity scanning to

identify and notify drivers of objects in the vehicle’s path. Currently, a connected car equipped
with this technology can monitor the location of up to 2,500 5G-enabled devices within a 1km range, such as smart phones being carried by pedestrians or cyclists. This information is fed into an algorithm that tracks the speed and trajectory of the device, selects the subjects most at risk and homes in to predict whether its movements could confl ict with the path of the vehicle. The driver is alerted to potential safety confl icts even where advanced cameras aren’t able to see obstructions, whether they’re beyond the visible distance or around corners or parked vehicles. “Beacon information containing

Vishnu Sundaram, vice president of the Telematics Unit at Harman, tells us about his vision of a safer, more autonomous future
is shared between the 5G-enabled devices and the vehicle,” explains Vishnu Sundaram, from Harman Connected Car. “The cars have a target classifi cation algorithm running on them so they can select those that are most at risk of causing a collision and alert if a safety issue arises.” Due to 5G’s low latency,
communication between the device and the car can take as little as 10 milliseconds, providing the immediacy required to issue warnings if a pedestrian is about to step into the road. The technology is anticipated to
hit the market in 2021/2022 and will increase as 5G becomes standard. “Harman has agreements in place with several OEMs, including most of the Germany luxury manufacturers, one
