Techniques for measuring extrinsic crash risk are provided. In some examples, a plurality of segments are instantiated in a road segment datastore, with each segment corresponding to a physical road segment in a geographic area and including segment attributes derived from digital map data as well as a risk attribute. From the digital map data, pairs of physical road segments that intersect are determined such that each pair has a corresponding pair of segments in the road segment datastore, and each segment is included in at least one pair. A connection between each segment in each pair is created in the datastore comprising connectivity attributes derived from the digital map data. Based on the segment attributes for a segment, as well as the one or more paired segments and their connectivity attributes, the risk attribute for each segment is updated in the road segment datastore.
