Sub-problem 4c: Separating the Conflict Points for TWSC Control
Step 1. Setup
Because of the wide median and the high speed rural type channelization of the right turns, it could be argued that the Okeechobee road intersection is likely to operate not as the single urban intersection considered in sub-problem 4a but as four separate intersections, with each intersection representing one of the conflict points, as shown in the diagram at the right. The separation of conflict points will usually give a more optimistic assessment of the operation than will the aggregation of conflict points into a single intersection.

Consider:
-
Why would separating conflicts produce a more optimistic assessment of the intersections?
- How are the conflict points inter-related?
