Hi all,
I would love to see the great OSRM framework supporting more dynamic
route calculations.
For instance, it would be great to be able to specify individual vehicle
profiles/parameters and avoid areas (e.g. road closures) on a
per-request basis.
As I understand, this required flexibility is contrary to the approach
of contraction hierarchies in general and thus very hard to achieve. The
routing can only be that fast because all dynamic input information is
pre-computed in the graph during the pre-processing, right?
However, I noticed that this topic was already discussed from time to
time on the list [1,2] and on github [3-5]. Plus there are similar
CH-based projects starting to support dynamic input at least to some
extent (e.g. GraphHopper Traffic Data Integration [6]). So in the end it
*does* seem to be possible, at least partly?
All in all, I'd like to know what is the current state of the art of
such efforts on the roadmap? What *is* possible and what is definitely
not? Is there anything in this direction being worked on currently or soon?
It would be great to hear any thoughts, updates and/or ideas from you on
this topic.
Many thanks and all the best,
Matthias
