Recently, Intelligent Transportation Systems (ITS) is becoming an important research topic. One goal of ITS is to disseminate important information among vehicles in a timely and efficient manner. In the ITS research community, inter-vehicle communications (IVC) is considered a way that may be able to achieve this goal. An information network built on top of vehicles using IVC can be viewed as a type of mobile ad hoc networks. Although several information dissemination protocols for mobile ad hoc networks have been proposed, how well they can be applied to a vehicle-formed mobile ad hoc network is still poorly studied. Without doubt, no matter what methodology is taking for designing an IVC-suitable information dissemination protocol, the protocol performance is fundamentally limited by the potential degree of physical-link connectivity. Thus, in this paper, some potential physical-link attributes of IVC networks, such as the lifetime of a transmission path between two vehicles, are studied based on reasonable vehicle traces generated by a microscopic traffic simulator. Although no specific protocol is focused on in this paper, the studied results can potentially contribute to performance improvement and/or protocol efficiency for any existed or developing protocol.
