Sub-problem 4d: Further Consideration of the Northbound Right Turn

Step 1. Setup

The analyses conducted at Krome Avenue and Okeechobee Road to this point have treated the northbound right turn as a stop-controlled movement. As shown in the previous problem, this results in an estimated capacity that anticipates a failing condition. Closer inspection of the assumption reveals that this may be too conservative and that it should be considered as a merge. As shown in the aerial photograph of Exhibit 3-24 and in Exhibit 3-32, below, the right-turn channelization is designed more as a merge than a conventional intersection.
