| Abstract: | In order to accurately detect the occasional highway traffic incident, a SVM parameter highway traffic incident detection algorithm is provided based on particle swarm optimization. The highway measured data set （I-880） is adopted and the support vector algorithm is tested for classification performance. The improved particle swarm optimization algorithm is used to optimize the parameters of support vector machine, and then the model under test is validated, resulting in the satisfactory effect. |
