The prediction of highway traffic accident injury severity with neuromorphic techniques.

This paper describes the use of one of the neuromorphic techniques û Artificial Neural Networks (ANN) Backpropagation technique to predict crash injury severity. The method of optimizing the number of neurons and epochs used in the ANN backpropagation architecture is presented. The paper also compared the_accuracy of the backpropagation method with that of the Ordered Probit (OP) model. The prediction accuracies of 83.3% and 65.5% were obtained for the ANN backpropagation and Ordered Probit (OP) models, respectively. The results indicate that a well structured network with optimized number of neurons and epochs, ANN can perform better than a traditional OP technique. It was also noted that the choice of the number of epochs and neurons is key to obtain an efficient ANN architecture. (Author/publisher).
