A discussion on traffic signal timing objectives, benefits and characteristics will lead to the presentation of basic traffic flow principles and traffic signal timing strategies. Isolated signal timing, covering pre-timed and actuated operation will be followed by relevant information on coordinated signal timing. A step-by-step signal timing example will provide the opportunity to explore guidelines on the calculation of signal timing parameters for different modes of operation under different scenarios, covering cycle length, change and clearance intervals, vehicular and pedestrian intervals, etc. An overview of analysis procedures and signal timing tools will briefly instruct on how to evaluate signalized intersection performance.
