Generalized force model of traffic dynamics
WebGeneralized force model of traffic dynamics. Floating car data of car-following behavior in cities were compared to existing microsimulation models, after their parameters … Webthe optimal velocity model and the generalized force model are discussed. These three models are compared with each other. Two macroscopic models: the LW-model and Payne’s model are described in section 2. These models consist of a continuity equation based on the conservation of vehicels and an equation describing the velocity.
