摘要
利用支持向量机的全局优化、适应性强、泛化性能好等优点,针对实时交通流数据的随机性、高维、非线性和时变等特性,将模糊支持向量机应用于高速公路交通事件检测问题中。在识别阶段利用60组实测数据训练模糊支持向量机,利用60组实测数据进行测试,测试结果表明,利用FSVM进行交通事件检测,识别率达到96.7%。
Support Vector Machine（SVM） has the advantages of global solutions, good adaptability, high generalization in theory. Due to the randomicity , high dimension, nonlinear, time -variant of the traffic flow data, Fuzzy support vector machine （FSVM） applied to high way incident detection In the stage of traffic incident recognition, sixty train data was used to train the FSVM, sixty test data was used to testify the effect of the recognition model. The results show that the recognition rate is approximate to 96.7%, which also proved the feasibility of the approach proposed in this paper.
