Vissim --> LumenRT

Hi All

I've succeeded in exporting a model from OpenRoads Designer together with an .ani.txt file from vissim. the model shows up correctly with the attached animation. Only pedestrians are not animated. Is this yet to be included in a future release or am I missing something. Currently I'm running LumenRT connect edition

Thanks in advance

  • Hi Damian,

    LuemnRT Connect Edition Up 2 (last version available on the Fulfilment centre) could import only traffic but not pedestrian.

    As far as I know, also in the next release (Update 3) the export tool is the same of the previous version.

  • Hi Mara

    It seems we are in fact able to control the type of objects imported from a .ani.txt file based on our inputs in the "VISSIM2Lumen.py". I've succeeded in importing all necessary models including the pedestrians. however the people remain static. given that pedestrian import was not included with the release, would it be possible for to reach a guide on the structure of the .py file for better understanding, or better a .py containing the necessary amendments (assuming this is the reason for static behavior)

  • Hi Damian,

    as the software does not import pedestrian (from *.ani.txt files), it is really interesting to know how you import them.

    For this reason we are not able to hep you with "static" behaviour. You can add people adding them directly into LumenRT, but of course they are not synchronized with the cars or red/green traffic lights.

  • Hi Mara

    Dave Burdick's "VISSIM2LumenRT.py" differentiates between time, and the type of object in the .ani.txt file by method of splitting lines into "tokens" and reading the value of a particular token, in which case vehicles are  "0". This is seemingly the reason for pedestrians not importing as their token is listed as "1" at the position shown below.

    Simplified, it seems that the file searches through the .ani.txt by vehicle value "0" and builds up a LumenRT library by randomizing through current .lob models by vehicle category stated in the .py file,(Dave's file is rather quite complex for someone as new to programming as I).

    As a quick test I stripped down a my LumenRT library under the "cars" category and placed a "walking" character in it, after adjusting the "yaw" in my .ani.txt where necessary.

    LumenRT then built up the model on export with the now "baked" animation, only the characters imported were static as compared to the vehicles.

    My best guess is that the lumenRT characters require a different coding structure for animation as compared to vehicles, which is what the .py file provided.

    In the end I simply chose to use the animated characters offered by LumenRT, a bit of a pain, but all that was currently possible. I just wish that this was made clearer sooner.

    Thanks for the assistance though.

  • We do not recommend to change the *.py file.

    Even if you were able to insert pedestrians, they do not work as vehicles. This should be make by dev team, but as I have said before, it is not included in the next release
