Abstract
In this paper we propose a comprehensive method to evaluate alternative projects in transportation network planning. This method has three stages.
(1) Analytical description of regional structure, describing the spatial distribution of commercial, industrial and residential activities using factor analysis and cluster analysis.
(2) Estimation of accessibility, of each zone using Hansen's concept of accessibility.
(3) Evaluation, by calculating the utility of locating activities in each zone before and after transportation network improvement, using the utility function approach.
Using this three-stage method, useful insights can be obtained about the general effects of alternative network improvement projects.
The method was used on a regional transportation network planning problem and the reliability of the method was examined.
