Mussone, L, Grant-Muller, S and Chen, H (2010) A Neural Network Approach for Motorway OD Matrix Estimation from Loop Counts. Journal of Transportation systems Engineering and Information Technology, 10 (1). 88 - 98 . ISSN 1570-6672Full text available as:
A method has been developed to estimate Origin Destination (OD) matrices using a neural network (NN) model and loop traffic data collected from a UK motorway site (M42) as the primary input. The estimated ODs were validated against matched vehicle number plate data derived from the ANPR (Automatic Number Plate Recognition) cameras which were installed at all the slip roads between junctions 3a and 7 of the motorway. Key research questions were: whether it is realistic to use the full loop data, whether particular features of the data influenced modelling success, whether data transformation could improve modelling performance through variance stabilization and whether individual ODs should be estimated separately or simultaneously. The method has been shown to work well and the best results were obtained using a square root transformation of the training data and individual models for each OD.
