Geospatial Data Science Techniques and Applications

Modeling transport-the phenomenon of people or goods moving in vehicles in space and time and being constrained in that movement by transport networks-is inherently related to geospatial data (Miller and Shaw 2001, 2015). People, goods, and vehicles are located somewhere at any time, in relation to each other as well as in relation to various mode-specific transport networks; they are coming from some location and heading to another location within some time constraints. The movements of people and goodscollectively defining the transport demand-can be solitary or shared, but are neither independent of each other, nor independent of the vehicles, which are defining the transport supply. In addition to the factors of space and time, economic, social, and individual factors also determine choice and behavior. That is why transport has long been recognized as a complex system and, as such, hard to model.
