Adaptive Traffic Control Systems

This newly updated online course offers a summary of fundamental principles, operational requirements and expected benefits of some of the frequently deployed Adaptive Traffic Control Systems.

The first session presents various traffic control systems and general characteristics, market state, and evaluations of the ATCS. The second session addresses SCOOT and ACS Lite, two systems with similarities in algorithms but various detection and communication requirements.

The third session presents SynchroGreen and InSync, recent ATCSs which recently gained a lot of popularity among the US customers. Finally, the fourth session focuses on SCATS (one of the oldest and widely deployed systems in the entire world) and other ATCSs from the US market.

Each session is divided into three major parts: the first offers a summary of fundamental principles of a selected adaptive technology, the second covers summary of operational and institutional requirements to run adaptive control, and the third presents operational benefits from available case studies.

Additional course detail is provided in the sections below.

  • What you will learn

    Students will obtain a significant amount of technical information to understand fundamental principles of operations, deployment requirements, and reported operational benefits (highlighted through exemplary case studies) of some of the frequently deployed Adaptive Traffic Control Systems.

    This information will help students to become familiar with these relatively new signal control technologies and develop a realistic set of expectations regarding their deployments and operational benefits.

  • Who should attend

    This course is intended for traffic engineers, planners, technicians, and decision makers in municipal, county, and state agencies interested in the operations, requirements and benefits of Adaptive Traffic Control System technologies, particularly those with the responsibility for the planning, design, implementation, operation, and maintenance of traffic signal control systems for urban areas.
