Tesla's latest software update, version 2023.44.100, has brought an innovative feature to its vehicles in China - a countdown for traffic lights. The update displays the traffic light status and the remaining seconds for the next intersection in navigation mode. The feature requires Tesla's premium connectivity.
The concept isn't entirely new; Audi introduced a similar technology years ago using vehicle-to-infrastructure technologies. Audi's Traffic Light Information system, part of Audi Connect PRIME, also offers a countdown for traffic lights and other benefits like recommended driving speeds for fuel conservation.
How Does It Work?
The functionality of Tesla's new feature is likely to be based on principles similar to Audi's TLI. It's speculated that Tesla might be using signals from traffic lights or government data accessed via the internet in China. This method would align with Audi's approach, where data on traffic light patterns is collected and analyzed to provide real-time updates to drivers.
The traffic light countdown is more than a convenience feature. It can improve traffic flow and reduce fuel consumption by advising drivers on optimal speeds and reducing unnecessary idling at traffic lights. Cities can use the aggregated data to optimize signal timing, further enhancing traffic management.
Trip Progress Bar
At the bottom of the photo, we can also see that Tesla has added a “progress bar” in the bottom navigation module that typically displays additional nav options and your estimated arrival time, distance to travel, and more. The progress is displayed with a red triangle marking the vehicle’s trip progress along the gray and blue line.
It seems that Tesla could add this feature to any additional regions in the future, as it doesn’t depend on any additional data, unlike the traffic light countdown.
The Future of Connected Driving
The adoption of 5G-powered cellular vehicle-to-everything technologies will enhance these systems. Such advancements could allow for near-instantaneous communication between vehicles and infrastructure, increasing driver safety and efficiency. There has been speculation of this before from Tesla when talk of the HELP system surfaced. Not only would it change the hazard light features, but if a Tesla encountered a hazard, it would alert other vehicles approaching the area of the danger.
Audi's journey in traffic management technology dates back to the mid-2000s with their Travolution project in Ingolstadt, Germany. This project involved direct wireless communication with traffic signals to relay information, significantly reducing time spent at traffic lights and decreasing fuel consumption. The expansion of Travolution to other cities and the evolution into TLI marked Audi's commitment to innovative traffic management solutions.
Introducing this technology will allow municipalities to improve traffic flow and pedestrian-friendly intersections. The continuous data exchange helps optimize traffic signal timings and reshape road layouts based on traffic patterns. For drivers, this translates to a smoother driving experience with fewer stops and starts, ultimately leading to more efficient and less stressful journeys.
