Key Steps

• The DTD, Transportation Performance Branch uses the AIMS from the statewide signal asset management database to provide a list of recommended treatments. The database includes records for key signal components, acquisition costs, installation costs, and condition rating derived based on other data sets such as structural inspections, maintenance work order history logged in SAP, and visual assessments from photogrammetric runs.
• The regions review the AIMS output and submit a list of desired traffic signal replacement projects list to the Division of Maintenance and Operations (DMO).
• The DMO Traffic Signal Asset Steering Committee and region staff work together in a collaborative process to finalize the project list based on fiscal constraints.
• The regions implement, manage, and deliver the selected projects.

• The regions submit their desired project list to the DMO Traffic Signal Asset Steering Committee.
• The finalized project list is sent to the regions for implementation.
