    Abstract: This paper proposes a simplified but reasonable uninterrupted highway model to evaluate
    the network connectivity performance for vehicular ad hoc networks (VANETs) from the view
    of both individual vehicle and global network. Three parameters: conditional connectivity of the
    communication pair of individual vehicles, global network connectivity probability, and the vehicle
    isolation probability are investigated. By combining the probability density function of inter-vehicle
    initial distance and the distribution of vehicles’ relative speed, which are both derived in this paper,
    the closed-form of conditional connectivity is obtained. To derive the closed-forms of network
    connectivity and vehicle isolation probabilities, the analytical model takes into consideration the
    key factors such as communication range, vehicle speed, and enter intensity. The analytical results
    are validated by extensive simulations. Our derived highway network connectivity model could be
    applied in the study of a number of metrics related to connectivity in VANETs
