8-Roadway Modeler

All of the supporting data has been calculated and built to run the model and create our proposed surfaces. We will run this model twice in order to display the Transition Templates ability in InRoads. When we created the roadway entries, the Use Transition Templates toggle was left unchecked. We shall run the model and observe the behavior. We will then edit our roadway entries to allow for the transition to occur and re-run the model.

19) From the InRoads menu, select Modeler→Roadway Modeler.

20) Select the Advanced tab.

The Advanced tab allows for the customization of the model and also allows for the overwriting of roadway entries, if necessary. The Advanced tab is often used in the troubleshooting of a model. There are eight areas in the Advanced tab which allow the user to determine the outcome of the model. These areas are: Mode, Sides, Superelevation, Transition Control Lines, Subgrade Intercept, Surface settings, Renaming at Template Drops and Critical Sections.

SAMPLE

ROADWAY MODELER


The Mode area allows the user to determine if catch slopes are to be used despite the roadway entries. The model can be run As Defined or as Backbone Only (without catch slopes).

The Sides allows for the model to be run either solely on the Left or Right sides, or both.

The Superelevation area allows for the use/non-use of superelevation data. Along with the ability to determine if superelevations are to be used, it is also possible to determine if the superelevation is to be applied to the First Layer (top layer) alone, or All Layers contained in the template.

The Transition Control Lines area allows for the ability to display, or not display the surface features, which are the TC names used in the template segments. It is possible to display all TC lines for all layers, or solely for the First Layer (top layer).

SAMPLE

ROADWAY MODELER


The Subgrade Intercept area dictates whether InRoads will extend the Cut/Fill sections in the subgrade layers to intercept with the First Layer or the Previous Layer. It is common to exclude Cut/Fill segments in subgrade layers in templates and to add a final segment to the backbone to close the subgrade to the endpoint of the Hinge section.

The Surface settings control the data to be included in the surfaces when the model is complete. The Empty Design Surface toggle determines if InRoads deletes all data within a surface if multiple model runs are done (i.e. troubleshooting a model). The Add Exterior Boundary will create an exterior feature for the individual surfaces created during the model run. This is extremely helpful if triangulation is expected after the model is run. The Densify Curves using Chord Height Tolerance allows for smoother curves in horizontal and vertical curves. The Use Elevation Interpolation in Unsuperelevated Backbone Areas forces InRoads to calculate surface points based on elevation and not slope in transitions between templates when the Transition Template toggle is used (see InRoads help for a more detailed description). The Add Transverse Features allows InRoads to create additional features for every template drop. This will ensure a smoother, and more accurate, triangulation of the model surfaces.

21) Verify the following: Mode set to As Defined and Sides has both Left and Right toggled. Verify both Apply To & All Layers are checked under Superelevation. Transition Control Lines are to be displayed and only for the First Layer. The Subgrade Intercept should also be set to First Layer.

22) Select the Report tab.

23) Activate the Generate Binary Report toggle.

24) Data click in the File Name: data field and type in train.bin. If the project defaults are not set due to permissions, it will be necessary to click the Browse… button and navigate to C:\train\model\ and save the file.

The binary file being saved at this point will be used to generate a detailed station by station report showing elevations, offsets, and slopes

by station. This type of report is generally known as the InRoads staking report.

25) Select the Main tab.

26) Verify that the Horizontal, Vertical, and Superelevation all reflect the proposed alignment.

SAMPLE

ROADWAY MODELER


27) Highlight train in the Roadway Definition, and existing in the Original Surface.

The Original Surface window allows the user to select which surface a model is run against

to calculate daylight points. This is only applicable to models whose templates are being controlled using the Cut/Fill segments. Any

type of table requires the selection of the target surface.

28) Verify the Create Cut and Fill Features is toggled off, and click Apply.

The Create Cut and Fill Features toggle will create a second set of features that are excluded

from triangulation. These features are considered redundant due to the decision table

setup.

InRoads will now run the model and display the T.C. lines and the cut and fill lines.

29) When the model is complete, you will see top and bottom layers appear in the Original Surface area. Close the Roadway Modeler dialog box.

SAMPLE

30) In the InRoads explorer window, right-click on the top surface and select Properties from the pop-up menu (or select Surface→Surface Properties…). Select the Advanced tab.

Notice the Symbology settings for both the Cross Sections and Profiles are set to “top”.

Because “top” existed in the preferences (civil.ini), these symbologies are correct. If the symbologies read “379612top”, we would have

to select a valid set of symbologies.

31) Close the Surface Properties dialog box. Save the proposed surfaces by selecting File→Save As… and changing the Save as type: pulldown to Surfaces (*.dtm). You will have to save the top and change the Active pulldown to show bottom. Click on Save each time and the file will appear in the active folder when the save is complete.

SAMPLE

The initial run of the model has been completed. By observing the behavior of the model around station 30+00.00, we can see the dramatic change in our model. The truck lane abruptly appears with no transition. There are two methods of correcting this. One method is to use the Transition Template toggle in the roadway library. The other is to use a horizontal control to “stretch” the template without the truck lane over a station range.

32) Select Modeler→Define Roadway… from the InRoads menu.

33) Double-click on the train roadway definition.

34) Click on New… to enter the beginning and end stations for our truck lane tapers.

SAMPLE

ROADWAY MODELER


35) The first station to be entered is 29+00.00. At this station, we will use the Recon-User template and the Train decision table. This will allow InRoads to manipulate the Recon-User template over the 100’ to resemble the truck lane template.

36) Toggle the Use Transition Template check box. Click Apply to create the roadway entry.

37) The next station to enter is the end of the transition to the Recon-User template. This transition will be 200’ long due to the fact that we are “dropping” a lane. Change the station to reflect 38+00.00 and select Recon-Truck Lane from the Template pulldown.

38) Verify the Use Transition Templates is toggled and click Apply to create the roadway entry.

SAMPLE

39) Close the Roadway Entry dialog box. The Edit Roadway dialog box should show 5 roadway entries.

40) Close the Edit Roadway and Define Roadway dialog boxes.
