Open Data Nation brings Street Safety Challenge to Cambridge, Massachusetts

Note: Open Data Discourse is now Open Data Nation!

To accompany the launch of the Cambridge Open Data Portal (, ODD hosted a Street Safety Challenge over the course of autumn 2014. The Challenge invited creative responses that made use of open public data and map from the Cambridge City Council Open Data Portal with details on pedestrian, bicycle, and car accidents in the City of Cambridge.

In just over six weeks, the Challenge data was viewed more than 2,000 times--the most of any open dataset in Cambridge that year. The eight Challenge submissions addressed policy-relevant issues such as how to format traffic accident data to enable trend analysis across the river into Boston and how to reduce accidents and encourage cycling by establishing a parked-car buffer.
