# Data sources for transport data

There are many good transport datasets out there, but they are not always easy to find.

## Useful data sources

The list below provides links to some key data sources that may be of use and interest, starting with the most universal and easy to use, and ending in rather specific datasets.

- UK geoportal, providing geographic data at many levels: https://geoportal.statistics.gov.uk
- Other national geoportals exist, such as this: http://www.geoportal.org/
- A good source of cleaned origin destination data is the Region downloads tab in the Propensity to Cycle Tool [@lovelace_propensity_2017] - see the Region data tab for West Yorkshire here, for example: http://www.pct.bike/m/?r=west-yorkshire
- OpenStreetMap is an excellent source of geographic data with global coverage. You can download data on specific queries (e.g. highway=cycleway) from the overpass-turbo service: https://overpass-turbo.eu/

### UK specific resources

Students can register with Edina Digimap.   It is a service which will allow you to download UK topographic map data.

UK census data can be accessed from several places including:
