Issue with OSM Web Wizard

[HillelPaley]

Hello all. I opened "OSM Web Wizard" using the py file (osmwebwizard.py), I clicked on "generate scenario", it showed me that it's loading, but when it's done, nothing happened, it doesn't open the scenario in sumo.gui, why is that? and what should I do to fix it?

edit: it created a file in the name: "2021-10-11-13-39-33", as it should, but the file is empty...

Might be the same issue as this, https://github.com/eclipse/sumo/issues/9304

Can you please have a look in the shell window which opened when you started the web wizard whether there are any error messages?

Hi. Is there a solution or progress in this error. I have encountered similar issue. When I submit "generate scenario" it stays in the "downloading map data" states for few seconds then it says "recovering" and resumes its initial state. Nothing seems to occur.

Thanks. alptekin. p.s. I doesn't change any settings or parameters. Keep the default city (Berlin) and doesnt evem change the area. (no change if i make the area smaller). I tried both in macos and windows.

The most likely cause is that the OpenStreetMap servers refuse the connection from your network. This error cannot be fixed from the SUMO side. The latest SUMO release tries to give some more feedback to make the problem more obvious (feel free to post the output from the shell window if you're using the latest release).

Please also try from a different network, sometimes OSM blocks big institutions because it receives a lot of traffic from there. Another option is to try to make the download as small as possible by disabling the polygons and/or making it a car only network

[aisiklar]

Hi, thanks for all the answers. to be frank, with respect, I dont think it is because of the network. Nevertheless, I tried applying the above suggestions (another network, no polygons and car-only network selected) and although the error statements were different, still it was a failure.

for the first case (polygon added and car-only network NOT selected) the error I see on the vs code terminal (for osmWebWizard.py):

I think it is due to variable "HOME_SUMO"... Because when I tried again with the suggestions (no polygons and car-only network selected) above, it gave another type of error (please check below for " error when the suggestions are applied").

I know it is too much text below. Just wanted to give the whole error, I feel / think it is due to assigning the SUMO_HOME but I dont know what to do.

Thanks a lot for any comments. alptekin

The error statements are below:

**** 1st case: standard parameters and config (polygons selected and car-only network not selected)**

Given all the error context was an excellent choice on your part. It reveals that your system does not define SUMO_HOME. Define this environment variable to point to /Users/alptekin/Documents/development/sumo-simulator/sumo

[aisiklar]

Thanks Jakob. In fact I had written the env. variable into .zshrc file but I suppose I forgot to "source" it... Or somehow it did not recognize it. :( Sourced the zshrc file and restarted (as it suggested in the installation manual). Now it works well. :) best, alptekin

[PARK090956]

Hello, I opened the OSM Web Wizard and created a network by creating a scenario. I want to change the edge of the network to a two-way lane, but it doesn't work. Is there any way?

[namdre]

See https://sumo.dlr.de/docs/Netedit/neteditPopupFunctions.html#add_reverse_direction (the function is now one level down in the edge operations sub-menu of the context menu.

@PARK090956 And you should start netedit first (by pressing Ctrl+t). And please do not post questions in old tickets, just open a new one
