TE-10 Traffic Signal Operations: Coordination for Corridors
DescriptionThis two-day course will focus on topics related to coordinating/synchronizing traffic signals along the corridors. This course will enable you to develop and evaluate the performance of two types of traffic signal coordination -- time of day and traffic responsive systems. For time of day and traffic responsive coordinated systems, attendees will learn how to determine good timing and coordinated solutions with innovative approaches for managing vehicle queues, progressing turns, and addressing potential gridlock situations, how to find optimal timing solutions, and how to safely accommodate non-motorists. Students will work on signal timing plans for several signals along arterials including freeway interchange signals; assess whether more complex timing solutions offer operational improvements; solve specialized problems such as offset intersections and diamond interchanges; and learn to perform analysis and evaluation of traffic volumes and field checks. The operational concept for traffic adaptive systems will be introduced. A basic knowledge of Synchro is helpful. For other Tech Transfer courses for the above topics beyond this course, please see Traffic Signals.
- principles of traffic signal coordination
- analysis of volume and system characteristics
- software and hardware requirements for signal coordination for each time of day, traffic responsive, and traffic adaptive systems
- use of SYNCHRO to develop time of day and traffic responsive timing plans
- find optimal timing solutions
- hands-on entering and understanding coordinated signal timing sheets
- performance comparison of the three timing strategies
- overall evaluation of maintenance of optimized signal timing and operations
- integration of arterial systems with freeway ramp metering and control systems.
What You Will LearnStudents learn to plan major signal coordination projects, when to use the different types of timing strategy (time of day, traffic responsive, traffic adaptive), how to proceed from data collection to satisfactory system operation and fine-tuning, and how to update signal coordination plans as traffic conditions change over time. Traffic adaptive software, a key to many "intelligent" traffic management systems, will be introduced.
Who Should AttendThis course is designed for traffic engineers from public agencies and consulting firms who already have some experience in signal coordination work, or who have completed prerequisite courses equivalent to Traffic Signal Operations: Isolated Intersections (TE-04) and Synchro and SimTraffic (TE-13).
