Summary of how it works: — can be unstandardized or standardized (0-100) -- requires choice of travel range 3 weights (optional): —Distance: smaller score for more distant services —Variety: higher score for more of different types of services —Relative importance: e.g. hospitals could get more weight than small service provider

This should be done, in two different ways.
