Sorry, forgetting myself. English phrase, kind of means on the agenda.

Never done anything with databases before, getting there though. I was worried 
about the numbers being to big with the meter co-ordinates compared with the 
degrees pgrouting where using in their doc's but that really shouldn't be a 
problem.

There are a few other problems with the osm data, no speed limit data and 
unreliable tagging of road types cause trouble. The algorithms simply try and 
find the shortest route, the bias towards major roads is done by weighting the 
length data using the road type data ie. a 2km 50kph road or a 3km 120kph 
road? 2/50=0.04, 3/120=0.025, the 3km road is 'shorter' to the algorithm. But 
the data only has road types and thats full of holes so I'm having to find a 
way of weighting without handicapping the roads with the missing data 
excessively.
Anyway, back to figuring out a 1960's database language and getting it to make 
the most out of a 1950's routing algorithm :)
cheers

Anyway,
