It shows with a heat-map where the demand is in real-time, the amount of waiting time for each taxi stops and also shows a graph of the next 24h with the best hours to work in order to allow the taxi driver to make a better schedule. It will reduce the amount of kilometers drove looking for clients, what means a reduction of the traffic and the resultant pollution.
