Controller Parameters


The brains of any signalized intersection still remains with the traffic signal controller. While there have been many hardware and software advancements over the years, the traffic controller is still remains one of the most under utilized tools in combating traffic congestion.

This presentation will first review all types of controller and cabinet standards, but also discuss where these standards overlap as to eliminate any confusion. From there, we will review basic timing parameters, but then move on to seldom used advanced features that exists in nearly all manufacturers of traffic controllers. Features will include but not limited to special phase sequencing, phase options, overlaps, scheduling, detector options, and more. Lastly, we will demonstrate how these features can be used for advanced traffic signal coordination to combat challenges such as congestion and pedestrian operation issues.

Following the presentation, the attendee should feel more comfortable exploring these advanced features and have the confidence to begin deploying these underutilized features and strategies.


Mr. Matthew Weisman has over ten years of experience in Civil Engineering with specialty focus in all aspects of Transportation Engineering and Planning. He served eight years as the Traffic Engineer for the City of Gainesville, Florida working his way from the Engineer I position to the Manager of the Traffic Operations Division and overseeing the division’s 30 employees. A large portion of his duties included the design, implementation, operation, and maintenance of the county-wide advanced traffic management system (ATMS), conducting traffic studies and reports for City transportation issues, and reviewing studies performed by other representing the City’s interests. The Gainesville ATMS has been recognized by Florida engineering associations and has won several awards. Since starting Hoffman, Weisman & Associates, Matthew has been providing expert-level guidance and services to government agencies, vendors, and consulting firms. In addition to Mr. Weisman’s general Traffic Engineering knowledge, his specialty skills include traffic signal operations, traffic signal timing, adaptive signal control systems (ASCT), ATMS central software, modeling and simulation, automated data collection, detection systems, layer 2 and layer 3 network design, programming, and deployment, TSM&O, active arterial management (AAM), dynamic message signs, fiber optic and wireless networks, and traffic management center design and operation.
