This project deals with the demand for public transport trips by using aggregate time- series monthly data over a long-range time period (1973-1996). The research task is to test a two-step procedure, where the mode-of-payment forms an aggregate logit sub- model, which is linked to the main demand model for public transport trips by a utility term. It also aims at testing various non-linear functional forms of the demand model.
Recent research findings show a broad spectrum of explanatory factors affecting public transport patronage, not only prices and travel times. The objective is to estimate which factors influences demand. By using non-linear statistical methods the magnitude of the influence of these factors will be esftmated. This paper deals with such a model for the Stockholm region, which has been estimated in spring 1998. The following types of de- pendent and explanatory variables will be examined:
* Ticket sales & Public transport trips data
* Ticket validity variables
* Fares, Prices and other Public transport events variables
* Activity variables
* Car competition & road network data
* Calendar & Climate data
* Public transport supply variables.
The Swedish Transport and Communications Research Board (KFB) and the Stockholm County Council Regional Planning and Urban Transportation Office has funded this re- search project.
