routing error with the routing plugin

[Al-Hun <alainruet@…>]

Hello,

I experimented a strange problem with routing using your plugin for JOSM.
I annotated a screen copy to explain :

• from B1 to C1, ok
• from B1 to C2, ok
• from B2 to C1, ok
• from B2 to C2, the proposed route use way A, which is much more longer... but :
  • C2 to B2 (inverted) is ok
  • B2 to C2 via C1 is ok

parameters of the route computing :

• shortest
• ignore one-ways

For the data all ways and points were verified :

• no one-way at all
• no barriers of any sort
• no restrictions

I use your plugin to detect bad or missing junctions in the ways, and I realized that strange behavior because I had false routes despite correct data.

You can have a look at this location : {{Coordinate|NS=45.80900470000001|EW=5.793915306798554|type=landmark|region=}}

Sincerely,

Alain Ruet.
