A system and method comprising a computer processor and memory to collect vehicle movement data at a traffic stoplight, predict a first stoplight cycle time with a first probability model indicating a first range of probabilities of the first stoplight cycle time; compare the collected data to the predicted data to generate a second probability model, based on the first model, that specifies a range of probabilities of a second predicted stoplight cycle time; apply a Gaussian noise function to the collected data to allow the requirement for data measurement to be reduced, update the second probability model by adjusting a set of probabilities of the second model with the noise applied data and generate an updated second model; and provide via a network to at least one vehicle computer, a recommended vehicle operating speed based on the predicted stoplight cycle time determined by the updated probability model, allowing improved vehicle fuel efficiency. The system can provide a route to a required destination, additional updated real time probability models taking into account time of travel during the day, and analysis of data compared with threshold monitoring. The system can also send notifications and the recommended vehicle operation to a hand held user device.
