There is no way of doing this "properly", because of reasons that other posters 
have mentioned. But it is possible to do it in a "lossy" way that accepts the 
fact that transitions across the borders are going to cause slight wrongness. 
For some bounding boxes, like islands (I do this for the british isles), this 
can work quite well, as movements of objects across the borders will be minimal.

I don't think there's any general off-the-shelf solution for doing this though. 
I developed my own code ( 
https://bitbucket.org/ris/oslmusicalchairs/src/e4c27e849345/planet.py ) to 
import changefiles into my project, cherrypicking the pieces of information 
that my app is interested in.

If you want to apply daily diff to an osm file you can do it and write 
only new file in some bbox or boundary, thats how I use it:


osmosis  --read-xml-change file="daily.osc" --read-xml file="base.osm" 
--apply-change --bounding-polygon clipIncompleteEntities="true" 
file="border.poly" --write-xml file="new.osm"


I use bounding polygon but bbox should work as well

If you want only changes you use osmosis to get change.osc from base.osm 
to new.osm

What do you think about something like:

cost:car_2axle = $X
cost:car_3axle = $X
cost:motorbike = $X
cost:truck_2axle = $X
.
.
.
cost:truck_Naxle = $X

And we can use something like $X/$Y is the price is different in the rush
hours.

 Diego

So, what value do you put into there?  The price per km/mile, the
maximum price, the minimum price?

As pointed out in the pdf above, in our case depending on what roads you
use to enter/leave the tollway and depending on how close you are to the
city, the toll varies per kilometre travelled.

and a date for the costings
because they always are going up
then which electronic tags can be used instead (for example E-tag)

This information is not best stored in the OSM database. A link to the
current information or not at all.

Before electronic toll collection, there were two major types of toll
collection - barrier and ticket. On a barrier toll road, you would pay a set
amount at each mainline or ramp toll plaza, meaning one could put the
default 2-axle amount on the barrier=toll_booth node. On a ticket toll road
you'd get a ticket when you enter that lists tolls to each exit; when you
exit you would hand in the ticket and pay that amount. This can't really be
mapped. (A slight variation would have a standard barrier, but if you enter
midway between the beginning and the barrier you'd get a ticket that
entitles you to pay less at the barrier.)

These two systems are still in use on toll roads that accept cash, and the
former can be mapped as such. Electronic-only toll roads may mimic a barrier
system, but will more likely make it more "fair" by charging based on
distance (and thus working like a ticket toll road).
