Identifying Optimum Intersection Lane Configuration and Signal Phasing Using Simplified CMA (Critical Movement Analysis)
Course Highlights

This online engineering PDH live webinar presents an extremely useful intersection planning technique that every traffic engineer and transportation planner should know. Once the concepts behind this technique are mastered, the transportation professional can use the technique to identify the best lane configuration and signal phasing for even the most complex isolated intersections.  Although the technique is “simplified”, dissemination of the technique is essential and is emphasized through worked examples.


SCMA is a planning-level analysis methodology that is simple enough to be performed by hand, and yet provides the analyst with an excellent feel for how a signalized intersection can be expected to perform under a given set of hourly traffic volumes. It is a great tool for analyzing intersections under future conditions, where traffic volumes may be approximate and where detailed signal timing information and traffic stream characteristics (such as percent trucks or the peak hour factor) may be unknown or known with little certainty.


This 2 PDH online live webinar is intended primarily for traffic engineers, transportations planners and other professionals who are interested in learning more about identifying optimum intersection lane configuration and signal phasing using simplified critical movement analysis (SCMA).

Learning Objectives

This PE continuing education live webinar is intended to provide you with the following specific knowledge and skills:

  • Knowing the exact steps required to complete the analysis
  • Understanding the advantages and limitations of this manual analysis technique
  • Differentiating  between conflicting & non-conflicting intersection movements
  • Learning how to adjust right turn volumes to obtain effective per lane values
  • Learning how to identify “defacto” lanes and account for their effect
  • Learning how to treat shared left/thru lanes
How it works

Alternatively, if your computer is not equipped with a microphone and speakers, you need to dial in using a phone line. From the webinar access and completion instructions, you will be also provided with a dial-in number to join the webinar and listen in. Furthermore, you will be provided with a link to download the webinar handout, or you can download it directly from you account, in the event you are unable to view the webinar on your computer screen.

Regardless of the connection method used, you will have the opportunity to interact with the instructor at the appropriate times either way. We recommend that you connect to the webinar approximately 10 to 15 minutes prior to the scheduled start time.

Certificate of Completion (PDH Credit)

Following attending the webinar, you need to return to the website and log in to your account to complete and submit the feedback form. Once submitted, we will email you your Certificate of Completion. You can also download it instantly, or at anytime, from your account where all your PDH records are kept for your convenience at all times.

PDH Accredited Webinars (including IA, NE, NY, OH and WI) live interactive webinars are accepted for PDH or CEU credit by all State Licensing Boards (including IA, NE, NY, OH and WI) mandating continuing professional competency, as they are prepared in compliance with the requirements of all State Licensing Boards. For additional details, please refer to your State Requirements.

Our PDH or CEU accredited webinars are developed and conducted by subject matter experts experienced in their field of practice. Our webinars are designed as live interactive web-conferences allowing you the opportunity to fully interact with the instructor at any time during the webinar from the convenience of your home, office or anywhere using your computer or mobile device.

Webinar Cancellation

If you register but you cannot attend due to unforeseen circumstances, we will issue a full refund if you notify us of your cancellation 24 hours in advance.
