Angular choice

Choice is calculated by counting the number of times each street segment falls on the shortest path between all pairs of segments within a selected distance (termed ‘radius’). The ‘shortest path’ refers to the path of least angular deviation (namely, the straightest route) through the system. (See: segment analysis)
