For the US and Canada there are in the ball park of 25-30 million 
segments based on Navteq data. There are a similar number of segments in 
Tiger althought Tiger does not have all the attributs needed to use it 
for routing. Western Europe as a similar, slightly higher number of 
segments in the 30-35 million range. If you plan around these numbers 
you should be good.
