Trisalyn Nelson, Director of the School of Geographic Sciences and Urban Planning at Arizona State University has created a crowd sourced website, BikeMaps.org, that is a unique tool that lets citizens build a database my mapping their riding experience including crashes, near misses, hazardous conditions and bike thefts. Combined with Strava data, this is a valuable tool to assist in bicycle planning decisions. Learn more about how it works and how you can help our community by sharing your data and riding experiences via this app or the website.
