Dangerous Areas for Cyclists

Dangerous areas are multi-block clusters of collisions with injuries or deaths. Clustering may reveal high-risk areas that would be missed by focusing on single points (like intersections) with many collisions. Clusters were identified by tuning a density-based clustering algorithm, Density-Based Spatial Clustering of Applications with Noise (DBSCAN).

The below map contains 50 of the most dangerous areas for cyclists in New York City.
