A Review Analysis of Optimal Velocity Models

To understand traffic behavior, we require a thorough knowledge of traffic stream parameters and their mutual relationships. This relationship between the traffic parameters results many researches yielded many mathematical models named Traffic flow models. This paper presents an overview of two great approaches of traffic flow: macroscopic and microscopic models. We aim to provide an historical overview of the development of microscopic models, particularly car-following models which are fundamental in the replication of traffic flow and thus they have received considerable attention. In this work, we present a survey of recent researches based on the optimal velocity model proposed by Bando and we discuss the capability of these models, their strong points and also their weakness
