摘　　要：近年来我国机动车保有量持续飞速增加,已经远远超出了城市路网所能承受的范围,导致大型城市中交通拥堵、交通事故和交通污染等情况十分严重。针对大型城市交通问题不断增多的现状,以微观交通仿真软件FLOWSIM为例,介绍了仿真系统在城市交通管理中的应用。该软件可以准确模拟我国城市交通中机动车、非机动车和行人混合行驶的现象,同时对FLOWSIM的使用方法与模型原理也进行了详细的描述。并且以具体交叉口为例,分析了该软件在城市交通管理与组织中的实际应用,其中重点介绍了中小型城市混合交通流管理和大城市在线实时交通评价功能。通过理论描述和案例分析,为大型城市解决交通问题提供了新思路和新方法。Recently the traffic related problems have become strategically important, due to the continuously increasing vehicle number. As a result, microscopic simulation software has become an efficient method in traffic engineering for its cost-effectiveness and safety characteristics. A new fuzzy logic based simulation software（FLOWSIM） was introduced, which could reflect the mixed traffic flow phenomenon in China better. The fuzzy logic based car-following model and lane-changing model were explained in detail. Furthermore, its applications for mixed traffic flow management in mid-size cities and for signalized intersection management assessment in large cities were illustrated by examples in China. Further study objectives were discussed.
