This internship project aimed to create an updated 2016 roadway network map and database for Middlesex County, as the existing 2006 map was outdated. The intern used GIS software to recreate the 1987 county roadway network as a baseline, then queried NJDOT data and compared to the 2006 map and Google Earth to draft a new map showing updated roads and their attributes. The outcome was a draft 2016 map and database of the county's 600-series road network for review. The updated system will benefit transportation planning and asset management in Middlesex County.
