Course Length: 1.5 Hours
This webinar was co-sponsored by ASCE's Transportation & Development Institute and ASCE Continuing Education
Purpose and Background
Sight distance is important in the design and operation of various types of road facilities. Poor sight distance can have adverse safety impacts and can result in collisions. Higher crash rates may result in tort litigation against the agency that owns the right of way. This webinar will identify the different types of sight distance that are important and the guidelines that are applicable to each type of sight distance. The discussion will include examples of locations where poor sight distance exists and explain the potential impacts of inadequate sight distance on various types of road users such as pedestrians and bicyclists. The impact of light conditions will also be covered in the discussion. The webinar will include the latest sight distance information from the Sixth Edition of AASHTO’s A Policy on Geometric Design of Highways and Streets (Green Book). A reference list will be provided that includes articles, websites, and other study materials.
Learning Outcomes and Webinar Benefits
You will learn about a variety of guidelines for sight distances and how they are applied in various situations. The webinar will introduce you to the various sources of sight distance guidelines and where quick reference summaries can be used to identify the best sources. You will also hear about recent research published by the Transportation Research Board on aspects of sight distance.
Upon completion of this course, you will be able to:
- Gain an improved understanding of the various types of sight distances
- Obtain better understanding of the importance of sight distance in design work
- Identify how to address the sight distance needs of all road users
Assessment of Learning Outcomes
Students' achievement of the learning outcomes will be assessed via a short post-assessment (true-false, multiple choice and fill in the blank questions).
Intended Audience
This webinar will benefit transportation professionals (engineers and planners) who work for consultants, cities, counties, and state agencies involved in designing roadway projects. This course is designed for individuals with some background and training in designing streets and intersections who are interested in improving the safety of these types of locations and making sure applicable guidelines are being met.
Webinar Outline
The webinar will cover sight distance for:
- Stopping and passing
- Traffic control devices
- Intersections and driveways
- Horizontal and vertical curves
- Underpasses
- Bicycle facilities
- Railroad crossings
- Pedestrian crosswalks
- Addressing sight distance restrictions
How to Earn your CEUs/PDHs and Receive Your Certificate of Completion
To receive your certificate of completion, you will need to complete a short on-line post-test and receive a passing score of 70% or higher within 1 year of purchasing the course.
How do I convert CEUs to PDHs?
1.0 CEU = 10 PDHs [Example: 0.1 CEU = 1 PDH]
