Abstract
Many traffic flow models are proposed for analysis of traffic jams. The fundamental diagram indicating a relation of flux and densities of cars has a phase transition in actual car flow data. A stochastic optimal velocity (SOV) model has been studied well because it expresses the transition. However, parameter tuning is necessary for the transition, and any tuning method has not been established. The present paper proposes statistical parameter estimation based on features of the diagram, and experimentally evaluates the validity.
