Hong Kong’s Smart Mobility Consortium (SMC) has staged a live demo showcasing Cellular-Vehicle-to-Everything (C-V2X) technology for connected cars.

C-V2X enables vehicles to have tactile exchange of information with other vehicles, pedestrians, and roadside infrastructure – bringing significant enhancements to driving assistance, traffic management and road safety for vehicles and pedestrians.

The C-V2X live demo was staged by SMC members HKT, Huawei and Hong Kong Applied Science and Technology Research Institute (ASTRI) at Hong Kong Science Park during the Intelligent Transportation System (ITS) Asia-Pacific Forum 2017.

The demonstration ran on HKT’s C-V2X trial network, using the 2.6-GHz frequency bands for Vehicle-To-Infrastructure (V2I) communications and the 5.9-GHz band for Vehicle-To-Vehicle (V2V) communications.

A regular vehicle fitted with C-V2X technology demonstrated multiple scenarios of how connected vehicles can enhance road safety, including:

  • V2V Do Not Pass Warning (DNPW) – DNPW warns the driver when a vehicle cannot safely cross to the opposite side of traffic to overtake another vehicle because of oncoming traffic.
  • V2P Vulnerable Road User (VRU) – In a non-line-of-sight situation, the vehicle can detect pedestrians’ presence in a “danger zone” and alert the driver with ‘Pedestrian Crossing Warning’.
  • V2V Blind Spot Warning / Lane Change Warning – The host vehicle driver can be warned whenever another vehicle on the adjacent lane is in a blind spot of the host vehicle.
  • V2I Forward Collison (Emergency Stop) – Alerts can be sent to other vehicle drivers in the vicinity via a roadside unit in case the host vehicle has to make an emergency stop.
  • V2I Intersection Collision Warning – A warning will be issued when two vehicles are approaching the intersection point out of the V2V communications coverage or in a non-line-of-sight condition.

“Three months ago, we shook hands and signed the MoU to establish the Smart Mobility Consortium,” said Alex Arena, Group Managing Director of HKT. “Today, we are working hand-in-hand to bring the first demonstration of C-V2X technology for pushing safe mobility in Hong Kong. The demonstration shows how C-V2X alerts drivers to dangers under different use cases on the road and emergency traffic conditions, which will make the roads safer and Hong Kong a better city to live in.”

The SMC said it would continue to work alongside the government, automobile industry, and other relevant industry stakeholders to push C-V2X commercialization and support the government’s Intelligent Transportation System (ITS) strategy.
