Optimal velocity car following model
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. WebJan 14, 2024 · The optimal velocity (OV) model that was initiated by Bando et al. [ 5] is a notable example of the engineering-based car-following model [ 6 ]. It assumes that each vehicle has an optimal car-following speed (CFS) dependent on spacing between the lead and lag vehicles.

The resulting optimal parameter values are V 1 = 6.75 m / s, V 2 = 7.91 m / s, C 1 = 0.13 m − 1, and C 2 = 1.57.
WebJun 13, 2024 · Bando et al. [ 15] proposed the optimal velocity (OV) traffic flow model, in which the optimal speed was only determined by the headway with the forward vehicle. The underlying assumption is that there exists an optimal running speed for each vehicle during the running process. WebThe integral part of the optimal velocity car-following models is the optimal velocity function (OVF), which can be derived from measured velocity-spacing data.
