交通拥挤状态模糊识别方法的设计与应用

交通状态是交通控制、交通诱导等管理措施的基础．在分析交通流运行特性的基础上，提出了交通流状态的拥挤和消散变化过程，并得出交通量和占有率对交通状态变化的敏感特性．建立了以交通量和占有率为输入量的交通状态模糊识别方法，并利用某路段环形线圈检测器的实测数据进行了仿真实验，实验的识别结果与实际交通状态相当吻合，可见该方法具有良好的实用性．

Application and Design of Traffic Congestion Identification Method Using Fuzzy Logic

Traffic condition is the basis of such traffic management as traffic control,route guidance.After analyzing the characteristics of traffic movement,the formation and scattering of congestion is presented.Then,a new traffic condition identification method based on fuzzy logic is put forward,establishing traffic volume and occupancy as input variables.Finally,a simulation experiment is undertaken with the data collected from loop detector.The result shows that the method proposed has great practicability and ...
