A soft computing approach to prediction of wheel induced rut depth: Appraisal of Artificial Neural Network

Que Wang, Feihu Leng

Abstract


An effort to predict wheel induced rut depth under the effect of wheel load, velocity, number of passage and slippage using artificial neural network (ANN) technique trained by three network functions of feed-forward network (FFN), cascade-forward network (CFN) and Elman back-propagation network (EBN) is presented. Data were used from the series of experiments where a total of 81 samples were available for training, validating and testing the neural networks. Comparing a one-hidden layer architecture with a two layered one, the best topology to yield better performance on the criteria of lower root mean squared error (MSE), and coefficient of determination (R2) was the latter provided that the developed model is not trapped in the over-learning drawback. It was divulged that the ANN with 4-20-14-1 topology provided the best performance in terms of MSE and R2 equal with 5.733×10-15 and 0.991, respectively. It was inferred that ANNs could reliably be applied as a promising tool for the prediction of rut depth created by wheeled vehicle trafficking.
