I think the main difference with their solution is that, since vehicles carry the equipment, 100% of intersections would be covered. Some cities have synchronized lights, but as far as I know, it is only at key intersections. Presumably, the increased efficiency comes from shaving off time at every intersection on your entire trip. Seems like they'd also get more data (number of cars, individual positions and headings) and may be able to do something smarter with additional data.

Using existing sensor to collect more data is an ongoing challenge for many municipalities. There is an add on module for signal controllers that can be used to count vehicles and depending on the detection type (video, inductive loop, or microwave) the counts can distinguish vehicle type and users such as car vs bicycle.
