[sumo-user] Hallo, again.. Just a question about left hand traffic

[Giovanni Hieronimus Maurice Pradipta Mite <necromancerhiero@xxxxxxxxx>]

Hallo, 

Sorry to ask again..

I have been trying to use lefthand traffic. I used the lefthand option in NETEDIT GUI (under Processing>Option>Processing, and ticked the lefthand box)

I saved the network. 

And then when i try to load the simulation from SUMO GUI, my simulation just crashed like that.

IF this option is wrong, then how should I do it? The Manual said something about --lefthand option; Isn't it just the same?

Thank you again.
