What would be the best way to simulate a mid-block ped crossing on a 4-lane roadway (2-lanes in each direction, no median. The crosswalk is uncontrolled, i.e. vehicles yield to pedestrians.

Would the best way to simulate this situation be to use a signalized 3-leg intersection with the 3rd leg being a imaginary leg with 0 vehicle volume and a ped phase with the appropriate # of ped calls to conflict with the thru vehicle traffic?

I would do as you said, but you may want to consider using an unsignalized intersection with "Yield" control instead of a signalized intersection This would cause vehicles to yield to pedestrians.

The drawback with yield control is that all vehicles would slow down when approaching the intersection incase pedestrians are waiting to cross. They would only stop if a pedestrian is ready to cross, or already crossing. I would study your situation in the field to see how motorists are currently reacting to the crosswalk, and whether the signalized or unsignalized treatments mimic what's currently happening in the field.
