The city of Ann Arbor, in the state of Michigan, has been the testing area (now completed with a cost of $ 25 million) for a communication system of government transportation department of USA which is based on the shipping of messages between vehicles with the ultimate goal of preventing accidents and more fluid circulation.
Those messages at the rate of one every tenth second, other vehicles likely indicate its position and velocity. In the future, of course, the information you will be able to receive and process will be broader, with data on accidents, delays or works on your route.
The objective of this first phase has been testing the operation of communication systems of the vehicles, which operate in the 5.9 GHz band.
In tests, the first vehicles that are being used have a range of about 300 meters to communicate with other “partners” of experiment. These vehicles can go factory and ready for this type of test or upgraded with kits, including from vibrating seats for important notices to a panel with all the information about the state of our environment.
So far no schedule to see this integrated system as is in street cars.
