Summary

Traffic stream models attempt to establish a better relationship between the traffic parameters. These models were based on many assumptions, for instance, Greenshield's model assumed a linear speed-density relationship. Other models were also discussed in this chapter. The models are used for explaining several phenomena in connection with traffic flow like shock wave. The topics of further interest are multi-regime model (formulation of both two and three regime models) and three dimensional representation of these models.
