# Alternative route calculations
|
|
|
|
Sometimes the routing result is not what you want, and you are looking for some
|
|
other way, following the same routing preferences, but not following the way of
|
|
the first choice routing result.
|
|
|
|
Maybe you don't like the first choice, or you are planning a roundtrip and don't
|
|
want to go back the same way. For this purpose, BRouter can calculate
|
|
alternatives.
|
|
|
|
This feature is well known from handheld-navigation systems, but not found in
|
|
online services. This is because these online services need to use
|
|
pre-calculations for fast processing and cannot handle individual routing
|
|
criteria. BRouter does not do any precalculations for specific routing profiles,
|
|
so it can do whatever you ask for.
|
|
|
|
When using a second choice route, you may want to recalculate the route using
|
|
[via or nogo points](vianogo.md) in order to define the overall routing
|
|
according to your preferences but have a route that is first choice except for
|
|
these explicit constraints.
