The research on Delay Tolerant Networks (DTN) has been activated aiming at a variety of potential applications toward ubiquitous society. The vehicular network is one of the promising areas for applying DTN. In this paper, the end-to-end delay characteristics for vehicular ad-hoc broadcast DTN is analyzed, where the dynamic vehicle mobility model is introduced. The analysis is applied to the two realistic road models, that is, one-way and two-way traffic models. The simulation study demonstrates validity of our analysis for use in generic vehicle networks.
