sample.networks: Sample networks for highway assignment testing.
In travelr: Functions for Travel Demand Modeling

Data files to support testing highway assignments.

1 2	data("Richmond.VA") data("SiouxFalls")

Two pre-built sample networks are available with travelr: the smaller “Sioux Falls” network and the much larger “Richmond, VA” network. The Richmond network includes static turn penalties and alternate link attribute names.

These sample networks load two elements through the data interface: a built highway network (including turn penalties where available), and a demand matrix for all vehicles.

network.od: demand matrix
network.net: network

The Sioux Falls network comes from public sources (specifically, Hillel Bar-Gera's site containing sample networks for testing assignment algorithms at http://www.bgu.ac.il/~bargera/tntp). The Sioux Falls network was adjusted slightly from the source version so that the free-flow zone-to-zone paths are more likely to have unique travel times, in order to facilitate testing against other traffic assignment implementations.

Other networks from http://www.bgu.ac.il/~bargera/tntp can be loaded into travelr format using function tntp.network. Trip tables can be loaded from the same source using tntp.od.

/emphNote for version 0.1: The Richmond network is not included initially since it is rather large. It may be made available during development in a separate package. It will be helpful if you attempt to load your own network and give us feedback on how that went (easy, hard, impossible) so we can clean up the functions and documentation.
