With an all London axial map converted to segments:
Total Angle to Total Angular Depth
R2 (180 degree turn) R^2 = 0.999
R3 R^2 = 0.998
R4 R^2 = 0.996
R5 R^2 = 0.993
There is the gradual curving off as you have shown for the topological case.
However, intriguingly, it also correlates to a strong degree with the
node count:
Node Count to Total Angular Depth
R2 R^2 = 0.997
R3 R^2 = 0.996
R4 R^2 = 0.994
R5 R^2 = 0.990
