Chapter 15: Geographic Information Systems for Transport (GIS-T)

Transport models are becoming more detailed, both spatially and temporally, in response to demands for better models and the availability of better data. This chapter focuses on the use of geographic information systems for transport (GIS-T) to provide better data for transport modeling and how better data facilitates improvements in modeling.

Transport researchers and managers around the world have been placed under increasing pressure for more accurate modeling of transport systems to improve operations to increase efficiency and effectiveness. Decisions must now take account of social, economic and environmental pressure and the possible consequences for all interested groups. The implication is that the information requirements will change significantly, with clear identification of costs and performance measures. The integration of transport models and geographic information system (GIS) has become more prominent in the analysis of transport systems. In addition, we see that GIS data enables the integration of modeling for both planning and operations.
