The purpose of this activity is to test your understanding of the relationship between detection zone length
and the basic actuated timing parameters.
•
Describe the timing processes for actuated traffic control
•
Describe how the length of the detection zone affects the setting of the basic timing parameters
•
Prepare a completed spreadsheet with the results of your analysis from the following tasks
