Vehicular ad hoc networks (VANETs) form when vehicles are equipped with devices capable of short-range wireless communication. Realistic vehicle trace modeling for VANETs simulations is a challenging task, which requires the reliable characterization of vehicular mobility. In this study, three different vehicle scenarios are proposed to analyze the difference between vehicle traces in multi-scenarios: city road, expressway and highway. Common trace modeling tools and characters of the scenarios are explored. Furthermore, three experimental scenarios are established using VanetMobiSim to produce vehicle traces. The experimental results show that the trend of the average speed versus the number of vehicles is different, and the vehicular density distribution demonstrates the realism of vehicle trace under multi-scenarios.
