Segment angular choice

Segment angular choice measures how many least angular paths lie between every pair of segments within a given distance. Angular distance is defined as the cumulative amount of angular change between all adjacent segments along the path. The “angular segment analysis algorithm produces better correlation with observed vehicular flow than both standard axial analysis and block-distance measure” (Turner, 2007)
