WebIn the optimal velocity model, acceleration of a follower car is determined according to a desired velocity, depending on the distance between this car and its leader. This can be formulated by the following: a1(t)C Vopt 1 x t Where represents the desired velocity of the car v i1 t (2) i ui ' V i 1 'xoptt1 i at time t C
WebA variety of nonlinear follow-the-leader models of traffic flow are discussed in the light of available observational and experimental data. Emphasis is placed on steady-state flow equations. Some trends regarding the advantages of certain follow-the-leader functionals over others are established.
