I'm trying to see if we can make Geopak create a parabolic superelevation. We are doing a project that is utilizing TxDOT roadway criteria and TxDOT requires a parabolic superlevation transition. Here is a link to the exhibit that shows what I'm talking about: http://onlinemanuals.txdot.gov/txdotmanuals/rdw/2-1.pdf. If Geopak will do it, then I'll just create an input file from that and load into Roadway Designer. I tried to see about creating an *.sup file based on TxDOT criteria for Roadway Designer but not sure I understand the components of that input file. Plus, not sure it will apply a parabloc transition.
Rick,
You will want to make sure and set this variable within the confines of your startup workspace along with the previous suggestions.
GPK_TXDOT_SUPER_PARABOLIC_TRANSITION=1
Thanks
