摘　　要：为了缓解方向性不均衡交通流带来的交通拥堵问题,国内外开始广泛使用可变车道技术。但现有可变车道导向判决的依据多为人为主观判断或是历史固定方案,方案普适性差、人工控制依赖成份大的缺陷,其功能没有得到充分应用。利用视频检测获得的车流量等相关参数信息,提出了基于非参数回归短时间交通流预测的智能可变车道的导向判决算法,实现了对可变车道随着实时车流量而自动变化的智能控制。通过应用测试和VISSIM交通仿真软件分析效果得出,交叉口日通行能力可提高大约15%～30%,总延误减少62%。In order to alleviate the direction uneven traffic flow with the traffic congestion problem at home and abroad for wider use of variable lane technology.Convicted on the basis of existing variable lane oriented mostly subjective judgment or historical fixed program,program universal,manual controls rely on ingredients defects,its function has not been fully applied.In this paper,the video detection traffic volume and other parameter information,intelligent variable-lane oriented decision algorithm for short-term traffic flow forecasting based on nonparametric regression,variable lane with the real-time traffic and automatically change the intelligence controlled.Through application testing and VISSIM traffic simulation software to analyze the effect of too intersection capacity can be increased by about 15% to 30%,the total delay to reduce the percentage of 62%.
