This paper presents the methodology for the estimation of traffic conditions in real time for the provision of Advanced Traveler Information Services in the city of Thessaloniki. The required data is collected by traffic models, flow measurements and measurements of travel time on major routes in the city. The proposed methodology includes the flow estimation based on travel time on fixed routes, short term forecasting of traffic volumes and spatio-temporal expansion of the traffic flows. All procedures have been developed for real-time applications in large urban road networks. The methodology presented is applied since May 2012 under the Intelligent Management System of Urban Mobility in Thessaloniki.
