    3D model for urban transportation

    Hi there,

    Good day.

    Kindly advise if you have come across any related journal or forums that discuss about the modelling of urban transportation system in 3D using GIS?

    Appreciate your input and tips.

    Cheers

    Try McTrans

    McTrans http://www-mctrans.ce.ufl.edu/ makes software and publications for various transportation applications. I believe (correct me if I'm wrong) that some of their custom software is created by Computer students in Florida for traffic modeling. Some of their demos are free also. That is where I would check first.
    Who's gonna re-invent the wheel today?

    I wouldn't consider use of GIS to make something three dimensional. Can you be a bit more specific by what you mean by 3D? Do you mean dynamic (pretty pictures, etc?). TransCad is probably the most popular regional model that produces those sort of outputs.

    If you're looking for something that shows little cars zipping through road networks and such, you need to investigate micro-simulation models such as Synchro/Sim Traffic. Paramics is probably the most powerful of the "new generation" of these...we've set it up to model a fairly large area of the City. However, it still uses "2D" inputs from our regional model (EMME/2 based).

    I use Synchro/Sim Traffic version 6 here. Version 7 does have 3-d now. Check out Trafficware's website. The cost might be up there, unless you have a license from a previous version.

    VISSIM for the microsimulation. In theory it can interface with Google Earth and Sketchup to make some pretty pictures too.

    Assuming you are referring to microsimulation, try here:

    umm how can a multi modal gravity model be 3-d?

    are we talking mocrosimualtion for public participation applications?
