Abstract:This study developed a GIS-based Intersection Inventory System (GIS-IIS) for the signalized
intersections on the state-maintained highway system of IDOT District 6. GIS-IIS is a tool to have an
easy access to intersection inventory data, photographs, and videos of each approach as well as an
ability to query the information. It is set up to be expended to include other types of intersection related
data. Procedures were developed to field data collection and processing along with a process for
integrating multimedia and other traffic signal information into the GIS framework. It is recommended
to expand the scope of GIS-IIS so it becomes a statewide intersection inventory system. The methods of
expanding GIS-IIS to create a comprehensive information system that incorporates information such as
traffic, geometric, construction, maintenance, and intersection accident data should be studied.
