摘　　要：回顾了几种常用的控制算法,针对上海市快速道路的特点,从平衡匝道排队与主线拥挤的角度,在ALINEA算法的基础上,进行一系列改进后得到EXPAlinea算法,并根据EXPAlinea算法设计了控制流程,对实施汇入控制后与控制前的交通流参数进行了比较。Several commonly used control algorithms were reviewed.In view of characteristics of urban freeway in Shanghai,from the aspect of balancing the ramp queue and freeway congestion,EXPAlinea algorithm was developed based on ALINEA after a series of improvement,and the control process was designed accordingly. The comparison of traffic data before and after implementing on-ramp merging control was given.
