This calibrates the trip distance beta, using the method described in Merlin (2020) A new method using medians to calibrate single-parameter spatial interaction models, JTLU. The basic idea is that we adjust the beta for the decay function until half the distance-weighted accessibility occurs in the median travel distance. For NHB, productions and attractions will be the same
