In South Africa we are often subject to power utility loadshedding by the state owned power utility. When this happens, the power to predefined areas is shut off at a predetermined time for a predetermined duration. This affects all traffic lights etc. Although the loadshedding schedules are known in advance, the specific impact on traffic that day in each location cannot be known with certainty. Often the traffic chaos snowballs exponentially when an area starts loadshedding and often the data fed back by all the Waze users is not sufficient or quick enough to adequately determine and update the best route options etc. Is there not a way for Waze to build some functionality into their algorithm, to combine scheduled loadshedding (feed forward) with user location and speed feed back, to come up with a better navigation result during loadshedding times. The state power utility Eskom publishes the load shedding schedules in advance and so it should be possible to pull that information in to the Waze systems as required.
