This repository contains code for the Melbourne freight model.
There is one script file, freight.R, which allocates freight volumes to network links.
It can be used in two versions:
- matsim output - produces origin and destination addresses for trips, used as an input for matsim to run the routing.
- full output - also runs the routing and calculates freight volumes for each link.
The matsim output is the version used in the JIBE model.
The code requires the following input files, which are available [to authorised users] at [insert location when known]. The code assumes that the input files are located in a data directory ("../data/") which sits beside the directory in which the script files are located .
