Diverging Diamond Interchange – Moving Everyone Faster and More Safely at a Lower Cost
This course covers everything you need to know about the DDI.
Innovative Geometric Design – A Better Way to Design for All Users
This course will explore the world of innovative geometrics.
Continuous Flow and Other Crossover At-Grade Intersections – Inexpensive Solutions to Significantly Increase Capacity
Participants will get in-depth knowledge and understanding of the CFI.
Superstreets, J-Turns and Other Innovative Intersections that Incorporate U-Turns
This course will start at the basics to describe the principles behind U-Turn intersections and what makes them so successful.
Getting the Most out of an Intersection Control Evaluation (ICE) Process
In this course, participants will learn what intersection options are available, how to screen various intersection options properly, and what factors to consider when deciding on the best intersection option.
Innovation in Pedestrian and Bicycle Design
This course dives into the principles of pedestrian and bicycle design best practices in urban areas that can be developed into new innovative ways to improve pedestrian and bicycle design.
Access Management and Innovative Intersections – The Perfect Match
This course will teach participants some of the basic principles of both Access Management and Innovative Intersections and then expand those principals to optimize safety and operations.
Addressing Congestion through the Principals of Supply, Demand, and Flow
Participants in this course will learn about the principals of demand and traffic flow that will enable them to develop their own innovative solutions.
Fundamentals of Intersection Design – Geometric and Traffic Design
This course will describe the fundamentals of intersection design starting from an uncontrolled simple intersection to a complex signalized intersection.
Fundamentals of Interchange Design in the 21st Century
Participants will learn about the basics of interchange design and different interchange forms, including a condensed discussion on the diverging diamond interchange.
Mr. Chlewicki has taught in over 25 US states and several other countries. He consistently scores high on evaluation forms and receives great positive feedback.
Well done with many useful tools for future design problems that may occur.
Very well presented information and the workshop kept my attention.
Really enjoyed the course – covered enough detail, but not so much to get bogged down.
I thought it was a great experience. Great to learn about different ways to improve capacity and safety at intersections. Lots of alternatives.
Very realistic alternatives with clear pros and cons. Explains what intersections work best based on criteria. Great course. Gil was extremely knowledgeable.
It was wonderful. Instructors knew what they were talking about and were passionate about the subject manner.
Thought it was an excellent presentation. Provides better understanding of intersection alternatives and appropriate application to solve design issues.
Gil has a lot of real world application experience.
Best documentation I have received at a seminar. It has relevant reference material, and in not merely a duplication of the PowerPoint presentation.
I appreciated the specific design details and rationale – much better than some other presentations where the material was very abstract and theoretical. Good pictures. Instructor very well prepared and interested in the material – a huge help.
Great instructor, very knowledgeable.
It will open my mind to not just “follow standards” and do what is right/safe.
This course was a great learning experience by providing many different approaches to solve a variety of problems.
This is probably the best training course I’ve ever been at. Great job.
The instructor was very confident in his knowledge of the subject.
Great photos for examples and great technical expertise displayed.
Gilbert was passionate and a very good instructor. Good job and good class!
Gil was thorough and enthusiastic, which made enjoyable/relatable presentation.
Was interesting that pedestrians play such an important / significant role, seems like it’s often forgotten.
I thought it was great. I appreciate the conversation on things done well and not so well as well as general tips to keep in mind.
Gave a good overview of intersection and interchange options while encouraging participants to be creative and think about things more.
Class was informative and engaging.
The concepts were clearly explained and backed up by theoretical and real-world examples.
I think Gil’s experience in the design and instruction of various intersections was most valuable. Very knowledgeable.
Very knowledgeable and fielded questions effectively.
