The goal of the work is to propose innovative methodology for motorway travel time estimation based on the switching among different methods and the fusion of traffic data and toll data sources. More precisely, two data sources are considered in this paper: inductive loop detectors data and toll data collection. Two classical methods are also used: the cumulative counts method and the speed extrapolation one. Toll data collections are used essentially to have a reference travel time to be compared to the estimated travel time. Keywords: Travel time, cumulative traffic counts, speed extrapolation, toll data.
