PenomienologIcal Driving Behavior Model of the Suburban Vlehicle-to-Vehicle Propagation Cannel at 5.9- GHz

Through a field implementation of vehicular ad hoc networks (VANET), we report the observation of a monotonic dependence of maximum relative velocity between two vehicles and their separation, for typical suburban driving. We introduce a hierarchical phenomenological model of driving behavior to describe this observation. As an example, we illustrate how we use this model to predict the expected Doppler shift with vehicle separation. Doppler shift computed from field measured spectra confirms the effectiveness of the model predictions. The model can be used to provide guidance in designing experiments with specific combinations of maximum velocity and separation, and to provide more accurate intelligent transportation systems (ITS) simulations.
