While viewing stops in the Stops tab, you can view the student assignments associated with the stops.     You may want to filter the stops first.  For example, you could use the School filter in the Stops tab to look at stops for a particular school.

Then click on the Operations sub-tab and select Student Assignments.  This will overlay blue student dots over or connected to the orange stop dots.  If you click on the blue dot it will indicate which students are associated with the stop.
