  Understanding human mobility patterns -- how people move in their everyday
lives -- is an interdisciplinary research field. It is a question with roots
back to the 19th century that has been dramatically revitalized with the recent
increase in data availability. Models of human mobility often take the
population distribution as a starting point. Another, sometimes more accurate,
data source is land-use maps. In this paper, we discuss how the intra-city
movement patterns, and consequently population distribution, can be predicted
from such data sources. As a link between land use and mobility, we show that
the purposes of people's trips are strongly correlated with the land use of the
trip's origin and destination. We calibrate, validate and discuss our model
using survey data.
