  A general stochastic traffic cellular automaton (CA) model, which includes
slow-to-start effect and driver's perspective, is proposed in this paper. It is
shown that this model includes well known traffic CA models such as
Nagel-Schreckenberg model, Quick-Start model, and Slow-to-Start model as
specific cases. Fundamental diagrams of this new model clearly show metastable
states around the critical density even when stochastic effect is present. We
also obtain analytic expressions of the phase transition curve in phase
diagrams by using approximate flow-density relations at boundaries. These phase
transition curves are in excellent agreement with numerical results.
