This paper presents a new technique for information access based on a combination of Geographic Information Systems (GIS) and conceptual structures as modeled in relational concept analysis. It is based on the idea that traditional relational databases restrict their data types to linearly ordered scales. Since spatial data are not linearly ordered, they cannot be modeled directly in relational...

Travel diary data (TDD) is an important disaggregate data source for transportation research. It is an example of multi-dimensional data that combines spatial, temporal, and attribute information. A proper representation of TDD can help researchers extract useful information from the data set. Current GIS is mainly designed to handle spatial and attribute data, lacking the representation of tem...

Transportation systems exist to improve individual accessibility. However, emerging applications of GIS in transportation (GIS-T) and intelligent transportation system (ITS) focus on throughput (the amount of system flow) rather than accessibility. Throughput is related but not equivalent to accessibility. Sensitive transportation planning requires rigorous, realistic and tractable accessibilit...
