The generalized bimodal traffic stream model and two regime flow theory
(1996) 13th International Symposium on Transportation and Traffic Theory (ISTTT13 1996) p.679-696- Abstract
- A new generalized bimodal traffic stream model deriving theoretically (i.e., via some underlying model of driver behavior) from (local) equilibrium solutions of a kinetic equation of vehicular traffic is presented and shown to have the correct flow behavior at jam density. This bimodal traffic stream model depends not only on parameters such as the desired speed w, the headway σ(0) at jam density and the minimum acceptable headway σ(w) at the desired speed but also on the probability η(k) that a vehicle located at a point at which the density is k will have a leading vehicle at spatial headway corresponding to the jam density. All of these parameters have some direct microscopic interpretation. Based on this new generalized bimodal traffic... (More)
- A new generalized bimodal traffic stream model deriving theoretically (i.e., via some underlying model of driver behavior) from (local) equilibrium solutions of a kinetic equation of vehicular traffic is presented and shown to have the correct flow behavior at jam density. This bimodal traffic stream model depends not only on parameters such as the desired speed w, the headway σ(0) at jam density and the minimum acceptable headway σ(w) at the desired speed but also on the probability η(k) that a vehicle located at a point at which the density is k will have a leading vehicle at spatial headway corresponding to the jam density. All of these parameters have some direct microscopic interpretation. Based on this new generalized bimodal traffic stream model, a novel mathematical theory underlying two-regime traffic stream models, one regime under uncongested free-flow conditions and another during queue discharge, is presented. The behavior of the generalized bimodal traffic stream model at dilute and condensed flow is analyzed, and is shown to have close similarities to some classical traffic stream models, in these respective limits.
