In this project, we analyze vehicular mobility in term of pairwise contacts (i.e., two vehicles approach within the communication range of each other) based on large-scale GPS trace data of over 20,000 vehicles we collected. The inter-contact time (ICT) distribution is studied and it turns out that the tail distribution of vehicular ICTs follows an exponential distribution, which is in sharp contract to the counterpart of human mobility. We also investigate the driven forces of such distribution and find city/road hotspots is a leading factor. In addition to contact-level mobility, we also extract the relationships between each pair of vehicles and find clear social structures existing in the network topology.
