Outline of Final Research Achievements

In-vehicle information devices such as car navigation systems and smartphones are now widely used and they provide drivers with a lot of information, such as traffic jam information, weather forecast, etc., by a communication function such as cellular networks. These services gather a lot of information from cars or traffic sensors on the road, which results in many small pieces of data being transmitted over cellular networks. We propose a method that, by predicting car behavior, reduces the amount of such data. We observe the amount of traffic data, simulate vehicle behavior, and evaluate our models. Our conclusions show good results.
