• Modeling Sidewalks and Driveways

  Modeling Sidewalks and Driveways Course Introduction

  (Course Duration: 46 minutes)

   

  Course Description

  In this course, you will learn how to grade the proposed sidewalk profiles for an urban roadway design.  

  Sidewalk terrace and driveway grades typically have constraints to direct drainage runoff, and to satisfy local safety requirements.  In an urban roadway design, the variance in the minimum and maximum grades for the sidewalk terrace and driveway is often a primary source of flexibility in the grading design, as it the case in this course.  To make the urban roadway design compliant with the design specifications, the sidewalk profiles must be graded to fit within the allowable elevation range, as calculated from the proposed back of curb elevation.  

   

  To demonstrate how to grade the proposed sidewalk profiles a common scenario and simple dataset will be used.  A setup corridor will be created to determine the allowable elevation envelope for both the inside edge of sidewalk and driveways.  The proposed sidewalk profile will then be modeled to fit within the constraints of terrace and driveway grades.  The proposed profiles will then be smoothed out and targeted in the proposed corridor model.

   

  This is among a series of courses included in the Urban Road Design Learning Path.  The workflow and design strategies used for Urban Roadway Design are derived from the Wisconsin Department of Transportation, and have been simplified for purposes of this training curriculum.

• Model Intersection Sidewalk Ramps

  Model Intersection Sidewalk Ramps Course Introduction

  (Course Duration: 54 minutes)

   

  Course Description

  In this course, you will learn how to grade the proposed sidewalk profiles for intersections in an urban roadway design.  As is typical in urban road designs, sidewalk ramps are needed at pedestrian crossings.  To ensure the sidewalk ramps meet ADA grading requirements, and that the terrace grades fit within the allowable grade range, a proposed sidewalk profile is needed.  The proposed sidewalk profiles will need to fit within the allowable elevation envelope, as calculated from the back of curb, and targeted in the proposed corridor model.

   

  To demonstrate how to grade the proposed sidewalk and ramp profiles, a common scenario and simple dataset will be used.  To lower the curb height for the sidewalk ramps, a curb cut profile will be created for each curb return alignment.  Another setup surface will be created to define the allowable elevation envelope for the proposed sidewalk and ramp elevations, and proposed sidewalk profiles created for each curb return region.  The proposed sidewalk profiles will be locked to the primary road edge of pavement and added as targets to the proposed corridor model.

   

  This is among a series of courses included in the Urban Road Design Learning Path.  The workflow and design strategies used for Urban Roadway Design are derived from the Wisconsin Department of Transportation, and have been simplified for purposes of this training curriculum.

• Make Refinements to Corridor Model

  Make Refinements to Corridor Model Course Introduction

  (Course Duration: 46 minutes)

   

  Course Description

  In this course, you will learn how to make refinements to a modeled, urban roadway design.  As is typical in all roadway design projects, refinements are needed to produce the best grading solution.  For urban roadways, this might mean adjusting the design profile to balance earthwork or address unwanted steep grades.  A refinement could require adding a driveway entrance that was missed.  Or you may want to refine the surface to make the contours and triangulation look more polished and smooth.  This course will address basic refinements you can make to your corridor models to improve your urban roadway designs.

   

  To demonstrate refinements that you can make to a modeled, urban roadway design, a common scenario and simple dataset will be used.  To address grading concerns at the intersection the proposed centerline profile will be adjusted.  Editing the design profile will trigger a ripple effect on the downstream setup surfaces and grading features.  The proposed profiles will be refined to fit within the updated elevation envelopes, and the proposed corridor updated.  A new driveway will be added to demonstrate how omitted driveways can be addressed, and a refinement surface will be created to “fine tune” the final grading model.

   

  This is among a series of courses included in the Urban Road Design Learning Path.  The workflow and design strategies used for Urban Roadway Design are derived from the Wisconsin Department of Transportation, and have been simplified for purposes of this training curriculum.

• Retrofit Centerline Profile

  Retrofit Centerline Profile Course Introduction

  (Course Duration: 50 minutes)

   

  Course Description

  In this course, you will learn how to establish the design profile for an urban roadway design.  Design profiles for urban roadway designs often need to be retrofitted to meet site constraints and strict design criteria.  In order to design a roadway that can meet these requirements, you need to determine where the variances are in the proposed grading design, then use a “reverse grading” approach to define the allowable elevation envelope for the proposed profile.  Once this elevation range has been determined, the design profile can be modeled to ensure your design is compliant.

   

  To demonstrate how to retrofit the design profile for an urban roadway design, a common scenario and simple dataset will be demonstrated. The proposed centerline profile for the project will be determined from the existing outside edge of sidewalk, on both sides of the road.  A custom reverse grade assembly will be used to define the allowable elevation envelope, and the profile geometry tools used to manually fit the proposed profile within the constraints.

   

  This course is the first in a series of courses included in the Urban Road Design Learning Path.  The workflow and design strategies used for Urban Roadway Design are derived from the Wisconsin Department of Transportation, and have been simplified for purposes of this training curriculum.

• Retrofit Curb Return Profiles

  Retrofit Curb Return Profiles Course Introduction

  (Course Duration: 70 minutes)

   

  Course Description

  In this course, you will learn how to establish the intersection design profiles for an urban roadway design.  The intersection profiles blend the secondary roadways into the primary road and lock the profiles between the roadways to keep the grading model dynamic.  The curb returns in the intersections, typically have minimum and maximum grading requirements, which can be addressed using a reverse grade assembly to determine the allowable elevation range for the curb return profiles.

   

  To demonstrate how to retrofit the curb return profiles, a common scenario and simple dataset will be used. The primary roadway grade will be  maintained though the intersection, and the secondary roads will be locked to the primary road edge of pavement.  A custom reverse grade assembly will be used to define the allowable elevation envelope, and the profile geometry tools used to manually fit the proposed curb return profiles within the constraints.

   

  This course is among a series of courses included in the Urban Road Design Learning Path.  The workflow and design strategies used for Urban Roadway Design are derived from the Wisconsin Department of Transportation, and have been simplified for purposes of this training curriculum.

• Grade Curb Cut Profiles

  Grade Curb Cut Profiles Course Introduction

  (Course Duration: 36 minutes)

   

  Course Description

  In this course, you will learn how to grade the curb cut profiles to model driveways in an urban roadway design.  In urban roadway designs there are a number of instances where curb heights need to be lowered to model driveways and sidewalk ramps.  Given the frequency of these instances, it is important to have a straight forward and easy solution to create and manage the curb heights for your project.  Using a custom curb cut assembly that allows you to control the curb height is an ideal solution to get this level of detail into your grading models.

   

  To demonstrate how to use a curb cut profile in an urban roadway design, a common scenario and simple dataset will be used.  A custom block will be used to locate the driveway geometry, and to place transition points for the curb height.   Curb Cut profiles will be created for the left and right curb heights, and PVIs added to lower the curb height in the driveways.

   

  This course is the first in a series of courses included in the Urban Road Design Learning Path.  The workflow and design strategies used for Urban Roadway Design are derived from the Wisconsin Department of Transportation, and have been simplified for purposes of this training curriculum.

• Create Proposed Corridor

  Create Proposed Corridor Course Introduction

  (Course Duration: 36 minutes)

   

  Course Description

  In this course, you will learn how to piece together the primary and secondary baselines to establish the proposed corridor model for an urban roadway design.  The primary road grade will leverage the retrofitted centerline profile, curb cut profiles, and custom curb cut assembly to lower the curb heights in the driveway.  The secondary baseline grading will incorporate the curb return regions for the intersection.  With these core features graded, a proposed surface will be created for review and inspection.

   

  To demonstrate how to model the primary baseline in an urban roadway design, a common scenario and simple dataset will be used.  A custom curb cut assembly, modeled in Subassembly Composer, will target the curb cut profiles created in an earlier task to set the curb height.  Partial assemblies will be used to model the intersections, and a top corridor surface will be created from links and feature lines.
