Re: [sumo-user] Multi-Clients in TraaS

Hi, Jakob:
I've got the latest TraaS. The multi-client rquires a debug sumo enviroment("sumoD"), could you please send me a debug SUMO package to install?
And dose SumoTraciConnection support multi-thread enviroment? The scenario is I want to get all the vehicles position in the network(latitude, logitude), but calling do_job_get will take a lot of time, so that I want to do this part in another thread.
Thank you for your help.
Your kindly Samuel.

Hello,
multi-client support for TraaS is not present in version 1.1.0. Instead you have to use the latest development version, currently available for download at http://sumo.sourceforge.net/daily/sumo-msvc12x64-git.zip

regards,
Jakob
