Electronic enthusiasts eight o'clock in the morning: Cadillac's car has become more and more talkative. Now they can “talk†to the traffic lights, letting the drivers know when the traffic lights will turn red. This feature is designed to reduce the risk decisions that drivers make at the last minute. Cadillac announced this week that it has successfully tested the communication technology called V2I (vehicle-to-infrastructure). In March of this year, the luxury car manufacturer also introduced a communication technology called V2V (vehicle-to-vehicle). For the first time, V2V technology has been applied to the Cadillac 2017 CTS car, which can “talk†to nearby vehicles with the same functions and transmit data about the road conditions through a networked system. V2I is now just a test function in the CTS demo car. General Motors' R&D department is also working with the Michigan Department of Transportation and McComb County Road Management to develop the technology. Cadillac is the first car manufacturer to use V2V technology as its standard feature in its vehicles. Therefore, it is not difficult to imagine that V2I technology will also appear in CTS cars in the near future. Cadillac tested its V2I technology near the GM Technology Center campus. It sent two traffic lights near the park to the CTS test vehicle to send relevant data. The automaker said that traffic lights can use the "dedicated short-range communication" (Dsrc) protocol, which is the standard used by V2V communication technology, to send information to the car to tell when the traffic light turns red. Then, the car that receives the message can alert its driver if the current speed will cause traffic problems at the intersection. V2I technology uses an encryption and privacy protection system similar to V2V technology. A Cadillac spokesperson emphasized this in an interview in March this year. For every networked system, privacy and security are the biggest concerns. However, the connection between V2I technology and traffic lights raises another question: Will drivers trigger an alarm when they accidentally smash a red light? Cadillac said that this will not happen. The traffic signal "may show that someone has smashed a red light, but it can't tell who or which car is smashing red" because the car does not transmit identity authentication information. Cadillac did not say when it will use V2I technology in its CTS cars or other models, but the company's spokesperson said their R&D team is "actively exploring" the feasibility of adopting V2I technology. Audi's own V2I technology has been applied to some of its models launched in 2017. However, this technology is limited to Las Vegas. The biggest drawback of this place is that its car-related infrastructure needs to be improved to take advantage of this new technology. “We need to work with the city government in many ways to ensure that the right infrastructure is in place.†A Cadillac spokesperson spoke of the challenge of building a V2I network. “It’s different from the V2V technology that controls the car. V2I technology needs to work closely with the city government to make a difference." V2I technology should be able to help create smart cities that are connected to each other. However, in order for V2I technology to develop in a real way, the city government needs to work intensively with automakers to build the way forward.
