Abstract

ABSTRACT: This paper proposes a dual boundary optimal velocity model (DBOVM) by substituting a dual boundary optimal velocity function (DBOVF) for the original one in the optimal velocity model. The speed adjustment mechanism is introduced to describe the rule of car-following within the dual boundary steady region. Field data are studied, which verify the assumption of DBOVM. Properties of traffic state transition in the law of DBOVM are analysed. Besides, the dynamic properties and the stability of DBOVM are studied by means of numerical simulations. It is found that the DBOVM can describe the capacity drop and hysteresis loop phenomena quite well. The stability of DBOVM is found related to the initial conditions on both boundaries of DBOVF. The speed adjustment mechanism has positive effect on the stability of DBOVM.
