基于Unity3D的公交车模拟驾驶系统设计与实现OA

As a livelihood project in the city traffic,bus plays an important role.The data show that the driver′s unsafe driving behaviors are the main cause of traffic accidents,so it is particularly necessary to strengthen driving safety training.Traditional training methods are relatively single and have limited effectiveness,while virtual reality technology has good interactivity and is suitable for developing bus simulation driving systems.In order to ensure the high immersion driving environment and real tactile feedback,a bus simulator is built based on a real car,which is used as the interactive end.Meanwhile,in order to restore the real bus operation scene,the virtual driving scene of real operation is built in Unity3D according to the B12 line in Zhengzhou City.After analyzing the dynamics model of vehicle movement,realistic vehicle driving control is achieved by programming the vehicle control script.Then,a traffic simulation environment close to reality was simulated based on the traffic flow simulation scene of the real road.After the subjective and objective verification of the system,the results show that the virtual vehicle has good acceleration and braking performance,and the overall satisfaction of the simulated driving system is high,which can play a good role in safety training for bus drivers.
