This solution will never work. Almost all cars should be equipped with the system, which is very difficult task. And just look at this sentence: "At the same time, vehicles leaving the jams are made to accelerate away quickly using automated cruise control." The car accelerating by itself... this is madness.

A lot better way to dissolve would be to show the drivers the traffic jam on the map so they take another way that is free. This is the main idea of this system:

I have used it and it really works, because you can see the traffic jam in advance and plan another route (or the navi can do it for you).
