Abstract |
In Sweden, large investment plans are being considered for rail and road infrastructure. At the same time, changes are taking place that either directly affect ridership (such as imposing a value-added tax on transportation) or indirectly (such as deregulation of air traffic). Clearly, there is a great need to be able to analyze how changes in price and level of service influence ridership. An overview of the models involved in a new model system for long-distance trips developed for Swedish national authorities is presented. The model system consists of nested logit models, partly estimated by the use of simultaneous estimation techniques. The trip data source is a national travel study conducted in 1984-1985. The choice structure of the model system spans from choice of access and egress mode over mode and destination choice to trip generation. There are different models for business and private trip purposes. The models contain cost parameters and mode-specific time parameters. The integrated structure implies that all variables affect all choice levels. The parameter values are reported elsewhere. Language: en |
