Abstract:Accurate collection of traffic data is essential for tactical efficient highway operations and strategic planning. Currently, the collection of such traffic data relies on physical sensors, which gather limited measurements of vehicle speeds and times as observed from fixed locations. These sensors cannot systematically acquire data on the mobility dynamics of individual vehicles and collective interactions among them, preventing the formulation of detailed models of vehicle flow within a transportation network. Finally, deployment and maintenance of physical sensors is expensive and time consuming.
