This webinar was co-sponsored by ASCE's Transportation and Development Institute (T&DI) and ASCE Continuing Education

Instructor:  Matthew Johnson, P.E., PTOE, PTP

Course Length: 1.5 Hours

Purpose and Background

In order to properly design or redesign a corridor, a designer must be given certain design parameters. Some of these design parameters include 95th percentile queue lengths, volume projections, and intersection warrant status. Corridor or planning studies provide those parameters. Sometimes, members of staff do not have the technical training to know how to properly scope, review, or comment on these studies. A properly scoped study, while more expensive on the front end, can avoid costly design changes and construction change orders. This class provides agency staff with a toolbox that will allow them to properly scope a corridor study and a checklist of what to look for when reviewing corridor studies.

Primary Discussion Topics

• Components of a corridor study
• Traffic Volume Projections
• What the results mean
• How to use these results
• How to scope the study for your conditions

Learning Outcomes

Upon completion of this course, you will be able to:

• Become familiar with what technical information a corridor study can provide
• Understand what that information means to an agency professional
• Be able to scope a corridor study to meet the needs of the agency

Webinar Benefits

• Discover how to use a corridor study as a cost optimization tool
• Learn how to use a corridor study as a planning tool
• Understand how the information learned from a corridor study can be used as a support for the Transportation Improvement Program (TIP)

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]
