Corridor Modeling When you first open the Corridor Modeling (CM) application, a new sub-folder is created under your working directory. \rddbs This folder is where any files are created that are used exclusively by the CM application.
Corridor Modeling GPK Job Selection
Corridor Modeling Tree Selection – Controls Importing of Data into Corridor Modeling
Corridor Modeling Workflow – Walks you through the CM process from Creating Templates to Labeling Cross Sections
Preferences Station Lock – Controls how the cross section interval is calculated in the Roadway Designer application. Slope Readout – Controls how the slopes are displayed to the user in the Create Templates and Roadway Designer applications. Horizontal Chord Height – When creating surfaces, controls the processing through horizontal curves. Vertical Chord Height – When creating surfaces, controls the processing through vertical curves. Template Library – Designates which template library CM applications will use. DTM Files Path – Designates location were dtm files will be stored.
DTM In order to use TIN files in CM, we have to import them. When you import a TIN, a new file will be created with the same name but using a .DTM extension. J2P022.tin J2P0200.dtm
DTM You can add both TIN and DTM files in the list box. Multiple files can be listed and imported simultaneously.
DTM Important! Only files that are listed in this list box will be available in Roadway Designer.
Geometry Chains and profiles from the GPK must be imported into the CM application.
Geometry When the geometry items are imported, a new file is created in the \rddbs subdirectory. This file is named by taking the gpk name and adding a ‘cm’ prefix and .algsuffix. job314.gpk cmjob314.alg GeoPak = GPK InRoads = ALG
Geometry When geometry data is imported, a drafting standard is always assigned to it. Later, you can build templates to target the chains/profiles by their name or by the name of the drafting standard.
Plan Graphics Since Roadway Designer does not read directly from plan graphic elements, we need a way to make the application aware of our graphics. We can do this by using the Plan Graphics import feature.
Plan Graphics We can read the plan graphics based on symbology, a DDB Feature or a MicroStation selection set.
Plan Graphics When using Symbology or Feature, we can setup a ‘search corridor’ based on a chain name, a side and a beginning and ending offset.
Plan Graphics If our plan graphic doesn’t fit nicely into a search corridor, we always have the Selection Set option. The user can just place any elements into a MS Selection Set and add them to the list.
Plan Graphics Once all of our items are setup in our list box, we can import them. The resulting alignments are stored in the .algfile.
ALG Viewer • The purpose of the ALG Viewer is two-fold: • Delete alignments from the .alg file. • Display alignments for review.
Smart Update - Geometry Data in the geometry database has a tendency to change throughout the life of a project. With that in mind, we need some way to keep our data in synch. In order to facilitate this, there is a functionality built into the Corridor Modeling application called Smart Update. Every time you open Corridor Modeling, it checks the data in the gpk against data previously imported into the .alg.
Smart Update - Geometry If a chain or profile has been modified in the gpk and is out of synch with the .alg, it will show up in blue. If a chain or profile has been deleted from the gpk and is out of synch with the .alg, it will show up in red.
Smart Update - Geometry Any data in blue should be re-imported to update the .alg. Any data in red should be deleted from the list box. This will also delete the item from the .alg.
Smart Update – Plan Graphics Similar to the geometry, the plan graphic data also has a tendency to change throughout the life of a project. The Smart Update functionality also works with the Plan Graphics. Every time you open Corridor Modeling, it checks the plan graphic data in the design file against data previously imported into the .alg.
Smart Update – Plan Graphics If a plan graphic has been modified in the design file and is out of synch with the .alg, it will show up in blue. If a plan graphic has been deleted from the dgn and is out of synch with the .alg, it will show up in red.
Smart Update – Plan Graphics Any data in blue should be re-imported to update the .alg. Any data in red should be deleted from the list box. This will also delete the item from the .alg. 1.4 Group Exercise: Setting Up Corridor Modeler Preferences
Chapter 1 – Quiz • Where can you find the Corridor Modeler Application? • What is the name of the subdirectory that is created when the Corridor Modeling application is first opened? • What is the extension of the Corridor Modeler preference file? • True or False: Only one GEOPAK TIN at a time can be imported. • If you were to import geometry from job999.gpk, what would be the name of the resulting file that is created in the /rddbs subdirectory? • True or False: The ALG file can be accessed by multiple users at the same time. • True or False: A blue line in the list of items in the Geometry or Plan Graphics means an item has been deleted. • RDP stands for? • Do the Global User Preferences (located under Application > Road > User Preferences) have any effect on Roadway Designer?
Create Template Now that we have our data imported, we are ready to step into the CM workflow. The first step is to access our Create Template application.
Create Template Create Template opens using the template library (.itl) specified in our preferences. The template library is composed of Components, End Conditions and Templates.
Create Template Components are Individual “pieces” that can be assembled into a template. They consist of things like pavement, shoulders, curb, walls, etc..
Create Template End Conditions are simply a special type of component that serves as the terminating point of the template.
Create Template Templates are a combination of components and end conditions that have been assembled to represent a particular roadway condition.
Create Template When components and end conditions are created, their individual elements are assigned styles (drafting standards). This controls how the elements are displayed. In the example here, this one component employs three different styles.
Roadway Designer Once our templates are complete, we can move into the next application in our workflow, Roadway Designer.
Roadway Designer We create a corridor based on an alignment and profile. We can create one or multiple corridors for our project.
Roadway Designer Next, we drop templates along our corridor based upon a specified beginning station and a specified interval. You can drop a single template or multiple templates depending upon the configuration of your project.
Roadway Designer The application is divided into 3 views – Plan, Profile and Cross Section. This is very similar to GEOPAK’s 3-Port Viewer.
Roadway Designer In addition to the cross sections at stations generated by the given stations and increments of the template drops, you also have the capability under the Roadway Designer Options to include Critical Sections. Horizontal Cardinal Points PI, PC, PT, etc. Vertical Control Points VPI, VPC, VPT, etc.
Roadway Designer Horizontal and Vertical Event Points. Currently there is no way in GeoPak to take advantage of Event Points in SS2. Event Points are locations of concern/interest along an alignment that you want the software to retain for annotation, template drops, additional cross section, and several other purposes.
Roadway Designer External Control Points – If a template targets an alignment (e.g. wall, ditch, etc.), then enabling this option will pick up all the critical points (PI’s, PC’s, PT’s, etc.) along this “external” alignment and include them as cross section locations.
Roadway Designer You also have the ability to generate stations at any location that you need. These are called Key Stations. These might occur at culvert crossings, driveway locations, etc..
Roadway Designer For the GEOPAK version of Roadway Designer, we have added the ability to import your superelevation directly from the GEOPAK shape input file.
Roadway Designer When you are at the point in your design when you are ready to create a finished model, you can do so through the Create Surface dialog. This will result in the creation of the proposed surface (.DTM) and an associated Tin file.
Roadway Designer The Display Components in Plan View option will result in the model being drawn into your design file.
Roadway Designer Your Roadway Designer session and all of it’s associated settings can be saved in an .IRD file.
Drive Roadway You can use the Drive Roadway application to review your completed model. 2.11 Group Exercise: Creating a Corridor and Surface
Chapter 2 - Quiz Which method is used to set a template as active in the Create Template dialog (select all that apply). A – Double click on the template name in the Template Library list B – Right click on the template name in the Template Library list and select Set Active True or False: The template preview window always shows the same template as the editing window. True or False: Points in a template (top surface and sub surface) are included in a single resulting design DTM. True or False: Multiple corridors can be created for a single project. True or False: Roadway Designer can use GEOPAK shape input files for setting superelevation.
Dynamic Settings • Used to help accurately place points for Components End Conditions and Templates • Defines Point Name and Style • XY= key in absolute coordinates • DL= key in delta coordinates from last point placed (defaults to the dynamic origin if it is the first point of a component. • HS= key in horizontal delta distance and slope from last point placed. • VS= key in vertical delta distance and slope from last point placed. • OL= key in delta coordinates from dynamic origin. • OS= key in horizontal delta distance and slope from dynamic origin.
