The frequency of investigations of toll road options in urban areas is increasing. Methods for estimating usage and revenue have in the past relied heavily upon aggregate methods based upon price elasticity and route choice behaviour of drivers before and after the opening of a major toll road in the southern outskirts of Brisbane. A method for analysing and predicting route choice for the widely used trip purpose categories is described and the estimated values of travel time from stated preference surveys (before the opening of the tollroad) and from revealed preference surveys (after the tollroad opened) are reported. Results of the application of the method to the Logan Motorway are compared with the observed level of usage. Logan Motorway are compared with the observed level of usage. The method can be readily incorporated into the standard travel demand forecasting procedures being used by Australian State Road and Transport Authorities (A).
