Abstract

Abstract: A method based on Adaboost RBF neural network is proposed for freeway incident detection in this paper.By analyzing the principles of freeway incident detection and choosing the relative parameters，the topology of neural network is fixed.Then an algorithm utilizing Adaboost integrating RBF neural network for freeway incident detection and steps of its processing are presented.Finally，a simulation experiment is given.The result of the experiment shows that this algorithm can highly enhance the performance of RBF neural network （with high detection rate and low false alarm rate） and also has a good performance of generalization，which assesses the effectiveness of its application to freeway incident detection.
