As part of federal mandates published by the Federal Highway Administration, local governments are required to upgrade their existing traffic control inventory, including all roadway/street signs, markers, and delineators to meet federal requirements. This includes ensuring the proper use of traffic control devices and maintaining them to meet retroreflectivity requirements. Banner’s role included surveying, inspecting, and recording existing traffic control devices along with identifying missing devices on all county, township, and city routes in Brookings County (excluding the City of Brookings). Banner developed a GIS-based system to collect and analyze data, and prepare construction plans. Ultimately the system was shared with Brookings County as part of their ongoing asset management system which meets federal requirements.
