Route building engine tuning framework

A method of tuning a subscriber travel route building engine. The method comprises presenting a user interface that is configured to receive a location cluster radius parameter input by a tuning application executing on a computer system, configuring the location cluster radius parameter input by the tuning application into a location cluster radius parameter of a route building engine application, causing by the tuning application the route building engine application to execute and determine a count of intersections of routes of mobile communication devices with a point of interest based on the location cluster radius parameter, receiving information about the count of intersections of the routes of mobile communication devices with the POI from the route building engine application by the tuning application, and presenting the information about the count of intersections in the user interface by the tuning application, whereby the route building engine is iteratively tuned.
