By the end of 2015, Toyota will make a new ITS (Intelligent Transportation System) safety package available on three models in Japan. The package, named ITS Connect, uses Japan's standardized ITS frequency of 760 MHz to receive and share data transmitted by external infrastructure and other vehicles. Equipping ITS on these three models will make Toyota the world's first automaker to bring a driver assist function that uses a dedicated ITS frequency to market.
ITS Connect uses vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication to provide drivers with the kind of safety information that cannot be picked up by onboard sensors. This includes traffic signal information and information about the presence of vehicles and pedestrians in blind spots.
By steadily expanding the range of vehicles equipped with ITS Connect, Toyota hopes to help reduce the number of accidents that occur near intersections. In Japan, this kind of accident accounts for roughly 40 percent of all traffic accidents.
ITS Connect
- Vehicle-to-infrastructure (V2I) Communication
Right-Turn Collision Caution
While waiting to turn right at an intersection fitted with the appropriate equipment, drivers are warned by an audio and visual alert under the following circumstances: if they take their foot off the brake and start to move forward when another car is approaching from the opposite direction, when a pedestrian is crossing the road to the right of the vehicle, or when there are other potential hazards the driver may not have noticed.
Red Light Caution
When approaching an intersection fitted with the appropriate equipment, if the signal is red and the driver does not ease off the accelerator, the system will warn the driver with an audio and visual alert.
Signal Change Advisory
When stopping at a red light at an intersection fitted with the appropriate equipment, a display counts down the remaining time until the traffic light changes.
- Vehicle-to-Vehicle (V2V) Communication
Communicating Radar Cruise Control
The system responds almost instantaneously to the acceleration and deceleration of other vehicles equipped with Communicating Radar Cruise Control. This allows two or more vehicles to maintain a safe distance and minimize speed fluctuations, making traffic flow smoother.
Emergency Vehicle Notification
When an ambulance equipped with a compatible communication device is sounding its siren nearby, the system notifies the driver with an audio alert, and displays the approximate location and distance of the emergency vehicle, as well as the direction in which it is moving.
Toyota believes that ITS technology will contribute to a future in which mobility means safety, efficiency, and freedom. To that end, Toyota has been developing ITS-compatible interfaces in collaboration with organizations in both the public and private sectors, with the aim of turning this kind of research into products as soon as practically possible. In 2013, Toyota participated in the ITS Green Safety public-private collaborative demonstration project to assess the social effects and acceptance of such systems and in October 2014, Toyota participated in the ITS Connect Promotion Consortium to make the necessary preparations for ensuring the smooth introduction and widespread adoption of the system. Going forward, the goal is to integrate packages like ITS Connect with other vehicle control technologies.

Cue more corporate welfare (sorry, infrastructure investment) to feather the usual suspects' nests (sorry, give the country and its happy, affluent population even more of a competitive advantage).
The word "redundant" springs to mind.

Um. OK.
As one might expect, about half of these seem a little goofy and the other half would be costly as options, but they are probably cheap if Toyota makes these standard. Personally, I find it weird when my brakes work at times I don't want them to. My car has similar features to those above, and the interference is disconcerting.
But basically, if you are not braking when you should be, you get some prompts and signals, which is ok. Funky lane changes and ignorance of oncoming traffic... those can be life endangering. Emergency vehicles? Red light timing? I guess there are times I would like more information about those, but.... are we getting into information overload territory?
Finally, the synched cruise control is not bad for wide flat areas, but for mountain driving, it might make for a jerky ride.
If people are negative about it, one must confront the question. If they save even one life, isn't it worth it? I am not so sure, but a lot of people are. How about 100 injury accidents? Or 1000 over five years? When you get to this stage, you see that Toyota is not merely reacting to make the world a better place. It is providing large amounts of social benefit. And the benefits pay for themselves.
