This map was produced using vehicle crash data from ODOT. Only crashes involving serious injury or death were included. The data points were merged within a 0.1 mile radius to look for general crash clustering. This method has its drawbacks, such as pulling crashes from parallel streets together. Therefore, this map should be viewed as a visual tool, not an analytical one. The data was mapped using CartoDB for the visualization and Leaflet for the actual web map.
