Traffic Problem

Hi Guys,

Creation a traffic simulation in Microstation using Lumen vehicles cell library looks fine - cars are coming on the path line (picture attached) and they are moving on preview animation tool as well. 

After exporting into Lumen there are two options keep coming. The first one is: cars appear from time to time into different places for a couple of seconds. So the good thing is they are moving but not along the path they are supposed to. Another option is: all the cars are visible right after Lumen starts but are not moving. The good thing is they all are visible.

Both options are not kind of result to be glad about.

Creation of simple four-corner shape and simple line object as a path just to check the software is working looks fine (picture attached) in both Microstation and Lumen.

Possible conclusion is something wrong with surface or paths which are in used .

It would be not so bad if someone tried to chech those two guys on his/her machine please. It could take a couple of minutes. File is attached.

Thank You for Your time.

  • Hi Ron,

    There are several objects in example video created by you (locomotive and several wagons). All these guy are sitting close to each other, kind of every next object is linked to the object before. The distance bewteen these objects stays always the same.

    It looks like there are some settings i missed to fix before creating the ani. As a result I have distance between the objects which keeps increasing all the time.

    Could you make a guess what these settings are, please?

    P.S. All numbers go to zero after choosing vehicles needed. And... I am not quite sure but it looks kind of pretty close to bingo. I suspect that there is something else I should adjust, isn't it, Ron?  

  • Hi Ron

    There are no reasons not to trust you. As for me it works but from time to time and it is not working more often than it does.

    Traffic simulation looks like an option but story is the same.

    Thank You and Ankur Ashesh for your help anyway.

  • Hi Maksim,

    I haven't had a problem with the distance of vehicles changing. Make sure you delete all the vehicles that appear when you initially create the lane and then add new cars to the lane. The new cars should maintain their positions relative to each other because they will all be traveling at the same speed.

    I explained my method for animating a train in the November 2016 Visualization SIG (See link below). It should answer your questions. My portion of the SIG start at about 18 minutes into the video.

    Here's a link to the SIG Videos. Choose 2016-11 (Nov) Visualization SIG: Articulated Vehicles and Traffic Simulation from the list.

  • Hi Ron,

    Your SIG tutorial is fine.

    I am writing about problem this topic was started with car vehicles. I'm still fighting against those guys. 

    Traffic processing from MS to LRT has no wish to be a friend of mine. SS4 was less capricious till it decided to stop working.

    Create traffic inside LRT looks fine but all vehicles stop moving next time LRT session starts.
