I did think that was the counts Jon included in his earlier post?
The 'highway' counts show 13532 bus stops, but yours must be in the 216 
independent objects?

The 'side' information has a number of areas that need covering other than 
just bus stop or halt location. No right/left turn from other side of road for 
example. And the problem of pedestrian routing showing things like safe 
crossing points adds another level of complexity.

p.s. adding all the pedestrian crossings and bus stops on the South Circular 
in London along with all the no right turn alternate routes and information on 
which lane you should be in would probably cover EVERY possible option. How do 
people cope around there? Took me 2 hours to get from Croydon around to the M4 
yesterday :( I'll use the M25 next time ;)
