Microscopic road traffic flow simulation models are increasingly being used to express the dynamic nature of traffic flow. These microscopic traffic simulations require vehicle movements to be modeled and calibrated. Since individual vehicles exhibit heterogeneity, the parameters within these submodels must incorporate some disturbances. However, due to limited observational data, the various parameters among individuals have not been well validated. The authors collected video data from an 800m section of an urban expressway over 1 week using 11 video cameras. By tracking individual vehicles on-screen, the authors were able to obtain vehicle trajectories. The authors applied this manually obtained data to investigate individual heterogeneity of vehicle movement; in particular, the authors focused on the multi-anticipative car following behavior by each section i.e., straight section, curved section and merging section and relationships between multi-anticipative car-following behavior and road geometry.

The DVD lists the title of this paper as: Empirical Analysis for Multianticipative Car-Following Behavior as Road Geometry Using Video Image Data.
