ACCESSIBILITY AS THE OBJECTIVE OF PUBLIC TRANSPORTATION PLANNING: AN INTEGRATED TRANSPORTATION AND LAND USE MODEL

Abstract The subject of this paper is planning of public transportation in sparsely populated areas. The paper consists of four main parts. In part I an analysis of the system to be planned is carried out. A comparison with a survey on the traffic and transportation models available in the literature, though very voluminous, reveals a lack of a general model-framework for planning public transportation in sparsely populated areas. It is the aim of the present paper to fill this gap. Part II discusses how to evaluate optional plans for the physical and socio-economic structure of a region and concludes that this must be done by means of accessibility. Acessibility is defined in this paragraph. In part III a model is presented which describes the interdependance between on one hand the demand of accessibility of the population and on the other hand the transportation system, both public and private, and the location of facilities and residential areas. The applicability of some standard transportation and traffic models is discussed briefly in this section. Finally part IV describes a case study, in which the models set out in part III are applied. Some results are presented with conclusions.
