[sumo-user] O/D Matrices and TrafficModeller

[Victoir V. <vei...@my...>]

Thank you for your reply Amie,
Where are you finding "helpers.ApplicationSettings"?  It seems like java code to me but all I can find is the jar file for TrafficModeller with no source code (unless I don't understand how to use a jar file), and I'm unable to find that string in the windows registry. I've also been unable to run the file as administrator in windows but will try in linux shortly.
Along a different path (should I never get TrafficModeller working), I'm wondering if there's a way to create a default traffic value in an O/D matrix. I'd like to define a few high value areas but have the other 100 or so residential streets have some low, default probability of being a source or a sink.

Thanks again,
Victoir

Unfortunately, I did neither find a way to search the mail archive nor
do I know how to properly answer already sent mails - so this is a
try.

I experienced the same problem. It turned out that "traffic modeller"
tries to store configurations values in the windows registry - which
caused a SecurityException on my machine. Maybe running the programm
as Admin is a fix.

go to "helpers.ApplicationSettings" and replace the methods "public
static String getDUARouterPath()" and "public static String
getNetConvertPath()" with your implementation. For personal use, I did
a quick fix with a fixed path. I know, it's not nice, but to check the
programmes capabilities, it should be fine.

I think the "hot spot" feature is quite usefull: You can graphically
define areas in which vehicles shall be 'incoming' or 'outgoing',
define the time and duarouter does the rest. However, I had no time
yet to try intensively.

Generally speaking, the tool is in a shape were it is quite good to
run it from an IDE to see all the error messages it normally would
hide from you.


Regards,
Amie
