Description

Build free-flow volumes from an assignment set

Usage

1
free.flow(aset)

Arguments

aset

An assignment.set

Details

free.flow produces a suitably structured set of numeric zero values for use in building costs; the result is a set of link costs by assignment class at free flow conditions.

If an assignment set is constructed using new.assignment.set, the free-flow volumes will have been computed by this function and will already be stored in the ff.vol element of the assignment.set.

Value

free.flow applies the assignment set cost function to a vector or matrix of zeroes and returns the resulting link costs
