Building vehicular networks in roads and high- ways is a challenging research topic with a large number of applications ranging from traffic jams and car collisions prevention to efficient route planning. The analysis of the distance between vehicles in roads is a key factor in, e.g., de- signing vehicular networks protocols or planning a supporting infrastructure to improve vehicular connectivity. This work proposes a Gaussian-exponential mixture model to characterize the time distance between vehicles in a highway lane, based on measurements collected at different locations in several highways of the city of Madrid, in Spain. The model arises from the observed behavior that some vehicles travel very close together, like in a burst mode, showing Gaussian inter-arrival times, while other vehicles are somehow isolated, showing exponentially distributed inter-arrival times. The ex- periments show that such a Gaussian-exponential mixture model accurately characterizes inter-vehicle times observed from real traces.

    • ...After comparing the maximum likelihood of our model with other distribution proposed in the literature (lognormal and exponential) we found that it is the best suited to mimic the behavior observed in a highway lane and furthermore provides some insights on drivers’ behavior, like the dependence between consecutive arrivals, that gives a meaning to raw data. This work has been published in [13]...
