| 摘 要： | 应用神经网络技术建立了基于三层感知机的平面交叉口事故预测模型,该模型的特点是可预测出具体事故形态的事故数.模型检验结果表明,预测精度达到了89%.在得到分事故形态的事故数预测结果后,基于"突出性"原理建立了一种鉴别事故多发形态的方法.

| Abstract: | The model for accidents prediction at the level crossing,based on the triple perception,is established applying the neural net techniques.Present model is characterized enabling to predict number of accident formation.Results of model inspection indicates the accuracy of prediction amouts to 89 percent.After prediction of formation accidents' number,there has been accomplished a method for distinguishing the accident formation frequently occurring,based on 'protrusion' principle. |
