• Re: Superelevation doesn't work with Display Rules

    Our superelevation control is applied to the EOPs of our top layer of pavement. The lower layers of pavement are constrained with a slope equation equating to the slope of the top layer. So, these slopes are constrained back to the point controlled point…

  • Re: Suggestions For Curb Template

    I gave this a shot using sequential shoulder rollover locks rather than template CDR's and it seemed to work well. I'm assuming the gutter is v-shaped and has a foreslope and a backslope. The bottom of the curb is then placed at the top of the gutter…

  • [Inroads v8i] Superelevation sections problem

    It seems that either there is a bug or I miss something in superelevation tool in roadway designer. I use wizard (ig. table method), adding sections and solviing overlaps - the superelevation is defined. Then I want to revise my superelevation's section…

  • Import superelevation data ASCII format?

    Does anyone have an example format (example ascii file) of the ascii import feature for superelevation control lines? The help menu states there are three values from each line it pulls from the ascii import, 1.) Station, 2.) finished grade left…

  • Superelevation Control

    I am using horizontal alignments to control the horizontal location of my median and edge of pavement curbs. Everything seems to work fine until I add superelevation control the the edge of pavement pivoting about the centerline. I used a single control…

  • Superelevation - point constraints between two sections, independent subgrade superelevation

    Hi all, I faced the following problem: There are two superelevation sections in my task - one for top layer and the second one for subgrade. These two layers are superelevated toogether (point constraints in template definition) till top layer reaches…

  • Re: Error in superelevation

    Greetings- Which program are you using? That will help in obtaining a more specific solution. It sounds like you don't have enough tangent between two curves, or enough between the end of a curve and the end of the alignment. Since AASHTO…

  • Modeling Superelevation Transition - Reverse Curves

    Running InRoads V8i - This is the first superelevation I have tried to create in a model. Two curves close together with superelevation in opposite direction, designed with a continuously rotating plane between curves. I first ran the wizard to set up…

  • Re: Inroads XM: Runoff lengths are wrong

    Here's my workflow up to this point:

  • Superelevation on Ramp

    Running InRoads V8i - When running the PGL along either edge of a single lane ramp, what is the best method for creating superelevation? The wizard requires three points and to specify two or four lanes. If I simply create control lines for the left and…

  • Inroads XM: Runoff lengths are wrong

    I'm using the AASHTO superelevation wizard, and after creating a superelelvation section, Inroads calculates the runoff length incorrectly. In this example, for a 6.4% superelevation, it thinks the runoff should be 34.56 m. I want it to be 79 m, which…

  • Problems with superelevation and shoulder rollover locks of my template

    Hello guys Am working on a design, a 4lane divided highway template with raised median barrier and kerbs together with cover drainage, in which the shoulder and the drainage are together, so i built the template and applied it to the corridor, but…

  • Re: Template and superelevation

    When you have your "template1" open in the template editor, click the "Test" button down in the lower right. You will get a message that says "Warning: this template has end condition priority conflicts." You'll need to go through each…

  • Roadway Designer - pavement warping vs. superelevation

    I am new to Geopak Corridor Modeler and am struggling with superelevation. Actually, pavement warping would be a better description. I have stations and cross slopes at exact locations for how we want the pavement to tip and where; at the beginning of…

  • Template point not available as super range point

    I have a pretty simple template that I'm using. It's very similar to a ramp typical where the BL is along the Left edge of the travel lane and I want to use the Left edge of my shoulder (LEOP) as my left range point when setting up superelevation control…

  • Re: inroads: superelevation (profile annotation)

    Piotr, Do you have Display Positive and Negative Superelevation toggled on the Superelevation leaf of the Annotate Profile command? Thanks, Jason Smithey

  • Re: Cant Alignment

    Jasmin, What you are seeing there is the “old” Superelevation name. In past versions of InRoads, the Superelevation was stored with the alignment and not with the corridor. Unless you are using Bentley Rail Track and assign point controls to that…

  • Re: Inroads XM: Runoff lengths are wrong

    Thanks for your time helping me with this Thomas, I figured out that setting the Maximum Delta G value is essential. This value should come from AASHTO2004 table 3-30, and is 0.44 for my road, not 1.0. I had disregarded it because I wasn't sure…
