The design of urban roads from limited local residential streets to arterial road standards. Horizontal and vertical alignment applications are detailed; consideration is given to drainage and auxiliary facilities such as parking, sidewalks and bus services. Students are required to incorporate all design elements in preparation for design drawings of a section of urban arterial road including intersection design.

Upon successful completion, the student will be able to:
Module 1 - Road Classification and Servicing Requirements
- Classify urban roadways and the relationship of pavement width to right-of-way width.
- State and define the purpose and characteristics of each class of roadway.
- State and discuss the other facilities provided within a normal road allowance.
Module 2 - Preparation of Plan and Profile Drawings
- State and define the basic preparation required and organization of a set of project drawings.
- Adopt a legend, prepare cross sections and incorporate standard notes.
- State specific information that should be shown on the plan and profile drawings.
- Prepare supplementary detail design information.
Module 3 - Preliminary Design Review
- Determine the extent of field information required and the need to confirm details of existing utilities.
- Obtain and interpret legal plan information for existing adjacent road right-of-way widths.
- Interpret existing design criteria and propose accepted criteria to complete the required guidelines where necessary.
- Examine the proposed and future utility requirements and evaluate the impact of future development proposals.
- Identify the need for any special structures that may be required, such as bridges or large culverts.
Module 4 - Horizontal Alignment Elements
- Prepare a plan view of the location of the proposed pavement for full roads, half-roads and laneways.
- State and define the terminology of horizontal curve configurations.
- Compute and present data defining the horizontal alignment including cul-de-sacs and curb returns.
- Determine adequate stopping and sight line distances for curves that may also incorporate vertical curve alignments.
- Utilize standard methods of incorporating vehicle 'turn-around' facilities.
Module 5 - Vertical Alignment Elements
- Define the criteria used in developing vertical alignment standards and its application to vertical curvature.
- Establish accepted maximum and minimum gradients and points of vertical intersection (V.P.I.)
- Determine the appropriate length of vertical curve for both crest and sag curves based on acceptable 'K' values.
- Compute the elevations along a vertical curve together with the preparation and the recording of the design data.
- Integrate vertical curves at intersections and a review of the vertical design considerations.
Module 6 - Road Cross-sections and Entrance Configurations
- Illustrate typical cross-section details for a variety of urban road standards including lanes and cul-de-sacs.
- Describe various methods of controlling surface drainage by utilizing crossfall techniques to provide a cost effective design.
- Identify different types of curbs, medians, and islands which may also incorporate parking facilities.
- Prepare standard cross-sections showing existing and proposed conditions and their relationship for quantity estimates.
- Illustrate recommended locations for driveway entrances for commercial/corner store developments, bus bays and driveways.
Module 7 - Urban Road Design Example
- Interpret urban road project design requirements and specifications.
- Prepare elevation tables, minimum vertical curve tables and design data sheets.
- Analyze horizontal alignment criteria and compute horizontal curve data.
- Calculate total project stationing from horizontal alignment data.
- Develop typical and special road cross sections.
- Design urban road vertical alignments based on specifications and controls.
- Calculate vertical curve data.
- Prepare trial plan and profile, and working cross sections drawings.
Module 8 - Intersection Design
- Determine the relative safety and efficiency of various types of intersections and establish methods of improving poor intersection layouts.
- Establish the priority of the design criteria through the intersection in accordance with the road classification and objectives of the intersection.
- Revise vertical alignment characteristics and incorporate one-way crossfalls to improve the riding quality of the intersection.
- Establish the desired radius of the curb return and prepare profiles along the curb returns to ensure adequate drainage.
Module 9 - Road Drainage Concepts
- Determine the location and spacing of catchbasins based on hydraulic capacity and pedestrian considerations.
- Incorporate major flood path routing to control surface runoff during adverse storm conditions.
- Estimate the flow capacity of a roadway, protection of private property and provision for emergency vehicles.
- Design roads based on gutter drainage profiles.
