I am trying to figure out how to determine distances for the municipal solid waste (MSW) management purposes in an island with over 70 counties/municipalities. I have a roads shapefile for the study area, and I digitized a point shapefile with various MSW facilties (landfills, composts, materials recovery facilities, transfer stations, and combustion facilities. The current facilities do have addresses (not included in the shapefile I created of course) but there are several proposed facilities that do not have addresses (so their positions are within the particular county as proposed by the proposing agency). I would like to know if there is a way (or ways) to determine distances for the following: 1) from the roads in each county to a particular facility (let it be landfill, MRF, compost, or waste-to-energy; which would be contained in the point shapefile), and 2) possibly from one facility to another (say from the roads in a county, then to a transfer station, and then to a landfill/compost/MRF/WTE facility). The roads shapefile is georeferenced to the study area's coordinate system (as defined by the agency that created it) and its fields include Type of road, road number, and length.
