The successful development of Intelligent Transportation Systems (ITS) depends on the capability of incorporating a vast amount of information about the location of facilities which generate travel as well as a realistic representation of elements of the transportation network in which travel...

In this paper we review attempts to develop CPM of individual travel behavior. CPM represent a linked set of computer programs together with appropriate databases which are designed to capture the essence of human decision making in different spatial situations. Used primarily for wayfinding and...

An interesting controversy has recently arisen regarding the relative effectiveness of map based versus route based environmental learning. Although spatial theory suggests that map based (survey) knowledge should be more effective, recent research shows some contrary results. In this paper we...

It is only in the last few decades that geographers have become aware of their special skills and knowledge systems for understanding space in domains other than objective physical reality. As this awareness has grown, however, it has become more and more obvious that spatial knowledge is much...

Travel behavior entails several interrelated decisions made by people, as well as the execution of routines not preceded by deliberate decisions. Furthermore, travel decisions are dependent on choices to participate in activities. A conceptual framework is proposed as the basis of a...

The purpose of this paper is to examine whether people in general understand elementary spatial concepts, and to examine whether or not naive spatial knowledge includes the ability to understand important spatial primitives that are built into geographic theory, spatial databases and geographic...

Spatial cognitive abilities play an important role in the use of GIS, although they have yet to be examined in a controlled experimental setting. This study aimed to develop an experimental design which measures spatial cognitive abilities in the use of GIS, specifically the map overlay...

This article reports on a survey of the use of buses in Santa Barbara, California, by 55 persons who are visually impaired (including those who are blind and those who have low vision). Findings on users’ frustrations, potential use of technological aids for travel, and perceptions of and...

The emergence of geographical theory was an inevitable product of the desire to systematize existing geographic knowledge and to use that systematized base to explore new areas of knowledge. Although the usefulness of theory and predictive models in geography is by now a matter of record, it was...

To date, most attention and compliance to the ADA mandates for equal access to transportation has been focused on the non-ambulatory/wheelchair bound traveler. These modification costs have been tremendous. Buses and trains have had to be retrofitted or new equipment purchased to provide...
