This is a bit "outside the box", but rather than going to the trouble of
locating, standardizing, and performing quality checks on 'free' road
network and address layers, I've lately taken to using the Batch Geocode
site to do many of my smaller (< 5,000 addresses) geocoding tasks -
http://www.batchgeocode.com/
I believe the Yahoo! Geocoding API this 'mashup' page utilizes is using
the very good GDT/TeleAtlas road network base maps, so the quality of
the results are typically as good or better than what I can accomplish
with free data and desktop GIS geocoders.
There are more advanced batch geocoding services available to academic
users without charge from the USC GIS Research Laboratory:

Hi everyone,
My apologies for the cross posting.
We are looking for a good quality road network for Phoenix Arizona to
allow students to geocode too. We have downloaded the Tigerline files,
but they are not very good for this purpose. Can anyone provide us with
suggestions for a source or two for high quality and free Phoenix street
network data?
thanks for your help,
Andrew
