Over half a thousand researchers ventured to solve the problem of traffic in big agglomerations in a competition sponsored by TomTom and held under the patronage of the Mayor of Warsaw. The outcome? Accuracy improvement of up to 60% and an algorithm that can be used in GPS navigation devices in order to avoid traffic jams. And much more.
