摘要
将交通流微观仿真系统和虚拟驾驶系统结合,提出并实现了驾驶员-智能体交通流混合仿真系统。介绍了混合系统开发的思路和多机数据传输方法,从平缓换道、转向灯闪烁和系统时间校准三个方面对混合系统进行了改善。最后利用混合系统对微观仿真模型的准确性进行了检验,结果表明在允许误差范围为5%时,跟驰模型可以准确地预测跟驰行为,换道模型的准确性仍然有待于提高。
By combining a microscopic simulation system and a virtual driving system,driver- agent traffic flow mixed simulation system was proposed and realized. This mixed system used communication technique to share data between the two subsystems. Performance of mixed system was then improved from three aspects, smooth lane-change, flashing turn lights and system time calibration. In addition, testing of microscopic driver models was conducted using this mixed system. Results show that while the car-following model can accurately predict car- following behaviors, the accuracy of the lane-changing model still needs to be improved.
