Course Title: California Roadway Geometric Design

Delivery Method: Live Online

Course Description: This 12-hour course will be presented over two days and will thoroughly analyze geometric roadway design. Geometric roadway design uses mathematical principles and geometry to design and create the physical layout and configuration of roadways, including the alignment, width, elevation, grades, and slopes. This extensive course will assess roadway characteristics and capacity, analyze roadway cross sections, discuss the level of service, and examine designs for curb returns, driveways, transitions, and vertical and horizontal curves and alignment. The course will reference AASHTO policy and ADA requirements.

Learning Objectives:

Learning Objective 1:
Learners will be able to discuss roadway classifications based on characteristics such as contextual safety and design speeds, as well as discuss the Safe Systems Approach, which according to the Federal Highway Administration, “considers five elements of a safe transportation system—safe road users, safe vehicles, safe speeds, safe roads, and post-crash care—in an integrated and holistic manner.”

Learning Objective 2:
Learners will be able to analyze roadway capacity, explain the importance of the analysis, identify conditions influencing capacity, and understand the relationships between speed, volume, and density.

Learning Objective 3:
Learners will be able to examine specific designs within a roadway cross section, such as median and median taper designs, turn pockets, lane widths, bikeways, shoulders, clear zones, bus stop and bus turnouts.

Learning Objective 4:
Learners will be able to consider types of users and vehicles when designing curb returns and utilize the correct curb ramp design and curb return radii.

Learning Objective 5:
Learners will be able to discuss the ADA design considerations and requirements for intersections, driveways, bus stops, and parking facilities.

Learning Objective 6:
Learners will be able to identify the general considerations related to sight distances, such as the height of the driver’s eye, the height of the object, etc. and calculate stopping sight distance, decision sight distances, passing sight distance and intersection sight distance.

Learning Objective 7:
Learners will be able to evaluate driveway design; specifically the design controls, the location, spacing, and geometric design elements.

Learning Objective 8:
Learners will be able to discuss the horizontal alignment and curves of turning roadways, calculate sight distance on horizontal curves and discuss the vertical alignment and curves of climbing lanes and escape ramps.

LUs: 12.0                                                                                           LU Type: LU|HSWs.
