For many years now, as discussions around the Internet of Things and smart cities have multiplied with the deployment of connected objects, there has been a relative lack of attention paid to the objects that fill and filter cities of all kinds. : the vehicles.
Cars, trucks and buses are as much a part of modern cities as are traffic lights, and they are increasingly connected to IoT networks. Thanks to the maturation technology known as cellular to vehicle connectivity or vehicle-to-all (V2X) cellular connectivity, cities and towns have increasing opportunities to shape public safety and influence the way vehicles interact with their infrastructure.
V2X is still an emerging technology, and most cars don’t have it as standard. Yet it is becoming more and more common, as Ford is committed to deploy vehicle-to-all cellular connectivity in all new US vehicle models from 2022. Several large-scale pilot projects of the technology are underway, and this looks promising for improving pedestrian safety, improving communication between first responders and more.

Georgia Welcomes New Pilots or Expanded Cell-to-Vehicle Pilot Projects
Look no further than Peach State for a hotbed of activity around V2X. At the end of June, the Georgia Department of Transportation announced a new phase of a program to turn an 18-mile stretch of Interstate 85 in Georgia into a test bed for connected vehicle technology, including V2X connectivity. The highway is known as The Ray, named after Ray C. Anderson, a Georgian businessman and environmentalist.
The project builds on a 2019 experiment in which the GDOT used Panasonic‘s Cirrus data management platform with the aim of improving road safety, reducing congestion and improving organizational efficiency.
The GDOT deployed six road units on the highway, which sent information from the vehicles connected to the Cirrus platform. Four vehicles from the department were then tasked with on-board technology to send data on speed, location and direction, as well as other vehicle data, such as directions for using windshield wipers or sudden braking.
As part of the new phase, the project adds seven new radios and 10 additional C-V2X connected vehicles, supplied by Kia Georgia. “The information provided by dual activity radios, known as ‘passenger information messages’ (TIM), will be transmitted and displayed in vehicles with a head-up display (HUD) which reduces driver distraction,” said one. Press release.
The GDOT noted that Panasonic technology gives it access to a connected vehicle ‘brain’ that is’ capable of receiving data shared between connected cars and trucks, such as accident, traffic and weather warnings, and return important and timely information – directly to connected cars and trucks, all in fractions of a second.
The dual-mode and dual-active functions of the road radios allow the GDOT to communicate the road infrastructure directly with the connected vehicles via dedicated short-range communication protocols (DSRC) and V2X cellular communication.
Meanwhile, the Atlanta suburb of Peachtree Corners announced a partnership with Jacobs and Qualcomm Technologies in June. deploy C-V2X technology for road infrastructure, traffic management and road safety.
The city will deploy road units equipped with Qualcomm’s C-V2X solution, and commercial vehicles equipped with the technology will also be used to demonstrate connectivity. “The implementation of C-V2X in the smart city environment not only demonstrates the benefits of C-V2X communications in a real-world, large-scale environment, but highlights the critical security communication capabilities of C-V2X. necessary to meet evolving transport needs, ”the city and businesses noted in a statement.
The advantages of cellular-to-vehicle technology
These pilots and others like them are important milestones in the evolution of V2X technology, as connectivity must be tested in real conditions so that government agencies can see the value of the technology and develop use cases. specific.
The potential is enormous. Imagine a world in which vehicles communicate with each other to know when and where they plan to exit freeways or change lanes. The infrastructure could also communicate with government fleets and send them automatically.
Additionally, V2X can enable better traffic management and alert cars in advance of construction work or alternative routes.
V2X can also help public safety agencies. For example, many police cars are equipped with license plate reader technology. V2X technology could be hooked up to such tools, and if a car is reported stolen after its license plate is read, that information could be sent wirelessly to other police cars in the area. The information could also be sent to connected infrastructure and surveillance cameras to help locate the car.
V2X offers public security agencies the ability to allocate the most appropriate resources for certain calls. By wirelessly communicating information between cars, law enforcement agencies can more efficiently send the nearest and most appropriate personnel to certain calls.
The possibilities for cellular-to-vehicle connectivity are seemingly limitless. The technology has yet to mature and be more widely deployed in vehicle fleets for it to have a major impact, but that day is getting closer.
