Traffic Signal Modernization Program
The Traffic Signal Modernization Program (TSMP) is a TDOT program designed to help communities and their local traffic signal maintaining agencies modernize existing traffic signal equipment and operations.
TSMP Grant Application Funds Eligibility Requirement
The TSMP project must be located on a State Route. Communities with a population below 5,000 (based on the 2020 federal census) are eligible for TSMP funds regardless of county CMAQ designation. Unincorporated areas within counties in non-CMAQ counties are also eligible for TSMP funds. However, communities with a population above 5,000 (based on the 2020 federal census) in CMAQ eligible counties and CMAQ eligible counties are not eligible for TSMP grant funds and those grant applications submitted will be eliminated from consideration. One county exception to this CMAQ requirement is Cocke County.
TSMP Grant Application Matching and Funding Cap Requirements
The TSMP project is a 100% state funded program (i.e. no local match required). The overall TSMP grant funds available through this grant application process is $750,000. Every project will have a different associated project cap up to $125,000 per project. The TSMP goal is to select at least one project from each TDOT Region.
