There are three accident model options.
All of the Accident geometric input is used by the Empirical Capacity Model (geometric) and is defined under Approach, Entry and Circulating geometry. The exceptions are the approach curvature (1/R0 the approach radius) and the fast path radius R1.
When varying geometry for capacity reasons, the effect on accidents must be checked to make a trade off where capacity and accident aims conflict.
