摘要
本文首先阐述了城市高速道路交通系统存在的关键问题和交通控制研究的必要性 ,然后通过高速道路实测曲线说明了该类型交通控制的特点 ,并对现有的城市高速道路控制三种方法进行评述 ,从中选择了现在广泛采用的入口匝道控制法进行深入探讨 .在详细论述各种入口匝道控制方法的适用场合和局限 。
This paper discusses the critical problems in urban freeway traffic systems and the need for traffic control. Some measured traffic curves are presented to explain the characteristics of such traffic control problems. Three control methods are evaluated, and the on ramp control, which is applied widely and discussed in detail. After the application and limit of the on ramp control methods are reviewed, a new research method, which combines multi objective optimization and hierarchical intelligent control theory so as to achieve the best performance of the whole traffic systems in a city, is proposed.
