Sub-problem 5c: Pre-timed vs. Traffic-Actuated Operation 

Step 1. Setup

In Sub-problem 5b, we explored various strategies for allocating green time with pre-timed control. Because of the isolated high-speed nature of this intersection, it is important that traffic-actuated control be used. In this sub-problem, we will examine the HCM treatment of traffic-actuated control to see how it differs from pre-timed control. 

Consider:

bullet

What are the primary operation effects of using actuated control?

bullet

What additional information is needed beyond the data already used in Sub-problem 5b?

bullet

How can actuated control improve the efficiency of a signalized intersection?

bulletHow can actuated control improve the safety of a signalized intersection?
