The development of a data base for individual choice models

It has been recognised at ARRB that there is a need to investigate a number of aspects of individual choice modelling of personal travel demand; in particular, the selection and specification of variables and the structuring of the mode choice process. This report underlines the steps taken to develop a comprehensive data base, on which such investigations are to be founded. It draws data from the 1970 household interview survey (his), for the Victorian city of ballarat, and from a computer simulated transport network model, of that city, as it was in 1970. All level of service (los) variables (eg car 'in vehicle time', car 'out of pocket cost') were simulated on the transport network model using the ARRB in house traditional transport planning package, tramp. The use of simulated los variables in individual choice models is a relatively new application of these variables, and as such, a number of problems were encountered during the extraction of them from the tramp system. The application of the multinomial logit program mlogpro is described, with the aid on an accompanying example of a program control card image deck. Various data configurations applicable to logit models (eg 'generic variables', 'mode specific' variables), are given detailed attention. The clumsiness of mlogpro as a modeller's tool is made apparent, while its reliability and potential as an educational program are recognised. The report concludes with a number of suggested refinements to los variables using his information, with the intention of removing strong inter correlation between the simulated variables (a).
