The IHE Middle East Branch would like to invite you to this joint technical webinar with WCTRS on Wednesday 5th April 2023.


This presentation focuses on discussing traffic signal coordination practices in various parts of the world. Traffic signal coordination has proven to be one of the most cost-effective traffic management strategies to minimize travel delay, vehicle stops, and related fuel consumption and green-house emissions. Some basic signal control concepts will be first introduced, including the two primary signal phasing schemes, the NEMA in North America and stage structure used in most other countries. The signal coordination principles will then be described, including key signal timing parameters such as cycle length, splits, offset, and phase sequence. Signal coordination under both fixed time and actuated control will be discussed. Case examples will be presented to illustrate different practices in various parts of the world.
