It is known that Google now enables one to
estimate travel time in rush-hour traffic in a
limited set of metropolitan areas (http://google-lat
long.blogspot.com/2007/08/how-long-will-it-takeat-
rush-hour.html). Google also attempts to predict
traffic conditions on a certain day and time based
on the live traffic data collected on a daily basis (Schwartz 2010). Our experiments in the study
area indicated that travel time reported by Google
Maps differed according to the time of the day
when the computation requests were issued.
Figure 7 shows the traffic condition along a route
in Baton Rouge.
