Urban data

As the world's population becomes increasingly urbanized, researchers and agencies have devoted increasing attention to understanding travel patterns in urban areas. Many of the existing data topics (temporal, spatial, travel survey) overlap with urban data as they are all various facets of the data needed for local governments and MPOs to make decisions about how to invest in infrastructure. The purpose of this page is to tie together some of the concepts of other data and models to bridge the gaps between the problems urban planners seek to solve, the models available to study these problems, and the data both necessary and available to answer questions related to urban travel.

We have attempted to link the relevant data types to the pages with more information on how that data might be used. We have also included links to key resources at the top of this page.

# Summary

Members and Friends of the TRB Committee on Urban Transportation Data and Information Systems (ABJ30) have compiled a list of commonly used data sources and tools. In compiling the content for this section, we went with data sources and tools that we regularly use or are exploring. We have included links to resources that we have found helpful. We also have included some information about emerging trends and issues to consider with respect to some of these data sources. Please also check out our TRB Committee website at http://www.trburbandata.org/.

This section was never intended to be an all-inclusive inventory, so if you notice a particular data source or related tool is missing, we hope that you'll add it in! We also welcome additional details regarding trends and emerging issues.
