Vehicles and other road users will be linked to each other and the road infrastructure to make traffic more efficient, cleaner, and safer. For example, Vehicle-To-Vehicle (V2V) and Vehicle-To-Infrastructure (V2I) communication enables cooperation and intelligent route management in transport networks. To achieve these ambitious goals, wireless links must become dependable: The information relevant for intelligent transport systems (ITS) shall be shared reliably within a tolerated latency. Challenges for cooperative ITS are posed by nonstationary time-frequency-selective fading processes in vehicular channels. Fortunately, the nonstationary vehicular fading may be characterized by assuming local stationarity for a finite region in the time-frequency plane. Thus, we characterize the channel by a local scattering function (LSF). High delay spreads are observed for rich scattering and high Doppler spreads characterize drive-by scenarios. These channel characteristics translate into packet error sequences exhibiting dependencies. Finally, we discuss packet error models of low complexity for large-scale cooperative ITS emulation.
