【Abstract】 The vehicle motion control method is realized based on the coordinates of the virtual vehicle and vehicle motion state.Based on the research of free-driving,car-following and changing-lanes,virtual vehicle movement strategies are implemented.The vehicle signal control is achieved by using collision detection mechanism in Vega Prime.The intelligent motion simulation of virtual vehicle is accomplished with VC+ + under the platform of Vega Prime.Finally,the proposed simulation method is verified by a real instance of regional traffic flow at Wudaokou in Beijing.The results show that it can achieve virtual intelligent vehicle motion simulation with high immersive and high human-computer interaction.The simulation results are consistent with the actual traffic situation.更多还原
