The study area is
simply referred to as Baton Rouge hereafter. The network
data used by ArcGIS are extracted from the data DVDs
that came with the ArcGIS 10.0 release, more specifically,
StreetMap North America. The road network data
are based on the TomTom (TeleAtlas) 2005 version 7.2 data
(according to personal communication with James Shimota
of ESRI on 28 June 2011). On the other side, data used
in the Google Maps are fairly updated. Most of this study
was conducted in the summer of 2011. In the case study
reported here, we used the data generated by the Google
Maps API tool on 8 June 2011.
