概要:
抄録:
he optimal velocity traffic flow model is one of the car-followingmodels which describe the behavior of cars by differential equations.In that model, each car controls its speed toward an optimal (safety)velocity, which depends only on the headway. We constructed a newcar-following type simulation model for traffic flow in a coupled mapform based on the optimal velocity model. We can easily simulate openroad systems with the model. The emergence of weakly congested flowinduced by noise is investigated. We observe the enhancement of thecar density induced by noise. The strong traffic jam hardly occurs inopen road systems. We discuss the problems of unrealisticacceleration in the optimal velocity model and the possibility ofspontaneous formation of strong traffic jams.
