Rob in Kansas,
Many route taxis will, at your negotiated fare, become a charter taxi in order to make the additional income the charter will generate. But essentially, you are not "taking a route taxi" but taking a charter taxi since you have indeed chartered it. You will not be paying the route taxi rate, but a rate that you negotiated with the driver.
The situation you mention specifically sounds more like you are generously paying for a route taxi. If they can still pick up others, then it is not a true charter - you have simply created your own temporary classification - a charter-route hybrid.
