Trouble adding random trips to scenario

[pv2-0]

Hi,

I am trying to simulate V2X communication in a traffic network and am having difficulty when importing the routes from my rou.xml file to my database. I created my rou.xml file using randomtrips.py and imported them to the scenario according to the instructions on this page. However, I am getting this message:

It seems like it is unable to import any routes because when I try to run my scenario, I get the following:

Eclipse MOSAIC will now shutdown.

I would appreciate any advice on how to fix this or if there is a simpler way to generate random trips in MOSAIC altogether. Thank you!

The latest release 20.0 requires to build a SUMO network file from OpenStreetMap using scenario-convert with the --osm2db + --db2sumo, or --osm2sumo, or --osm2mosaic option. From your output it seems that your net-file was not generated using scenario-convert, but directly with netconvert. However, the upcoming release will fix this and will allow you to import any net-file and corresponding route-file you want. You have two options now:

1. You build your scenario with scenario-convert using an OSM file as input. If you use the option --osm2mosaic -i path/to/map.osm --generate-routes a fully functioning scenario should be generated with some vehicles driving on some random routes.
2. You wait until the next release which is scheduled for end of March. With this version you should be able to import any network- and route-file you want.

Thank you! Once I generate the routes, I still have to spawn vehicles in the mapping_config.json file, right? How do I specify for half of the vehicles to be of one type (ex. not automated) and the other half to be of another type (automated)? Do I have to spawn vehicles individually and assign each a different route id? It seems like there should be a better way.

Yes, you have to define so called "vehicle spawners" in the mapping, which each generate a constant flow of vehicles. Each flow is assigned to one specific route id, but you can have multiple vehicle types for each spawner, even distribute them unevenly by using different weights. Just have a look into the Barnim scenario and tutorial, in which different vehicle types are assigned to one vehicle spawner.
