Re: [sumo-user] Visum network import

[Daniel K. <d.k...@go...>]

Hello Patryk,

Oh yes. I was aware that Vissim networks may use different languages, but
did not know that this is also the case for VISUM networks.
I'm asking myself how much effort is spent during VISUM development for
keeping the integrity between different versions and languages. Of course,
the network importer could be extended, but a) I will not have much time to
do this, and b) there is a big issue with VISUM versions, as both table and
column names change over time. So your tables are partially in Polish and
partially in English? This will make it even more complicated.
Are you capable to program c++ or do you have someone at hand who is? I
could give you some advices.

sincerely,
Daniel
