[OSRM-talk] Limit particular points in a route at runtime

[Daniel Patterson]

Hey François,

  The only way to achieve this with OSRM would be to apply large penalties
to barriers/tolls.  You'll have to pick a penalty value that's *just right*
- enough that 0 or 1 will be acceptable, but 2 would force the engine to
find another route.

  Because OSRM doesn't have dynamic costing options, you can't do something
like "penalize the first toll with 0, penalize the second toll with 1000" -
for that, you'd need to be able to run a more customizable routing
algorithm.

  We have muttered about implementing A* on the edge-based-graph which
would make this possible, but so far, nobody has put the time in to
implement it.
