Traffic Signal Control

This GLOMACS Traffic Signal Control training course will provide a comprehensive understanding of the purpose, benefits, components of a traffic signal control system, in addition to practical tools and techniques utilized in data preparation and modeling processes.

There are two primary practices of signal control systems in transportation studies. First, a traffic problem is addressed for one or multiple urban arterials, where each arterial consisting of several intersections that are controlled by traffic signals. Arterials are usually designed to move large numbers of travelers with different modes, including automobile drivers, transit riders, bicyclists, and pedestrians, through the system with minimum stops and delays. Based on the performance objectives, these coordinated systems often give priority to specific travel modes (e.g., transit riders). Second, the focus of the study is on the operation of an individual signalized intersection. Accordingly, this training course is set to deliver guiding principles for both practices in traffic signal control systems based on global standards.

This GLOMACS training course will highlight:

• Purposes and Benefits of the Traffic Signal Control
• Exploring the System and Providing a Framework
