About Signal Optimization Shared Services

What we do

Signal Timing & Optimization projects conducted by the Metro Traffic staff are being established as a shared service to provide Districts with needed expert signal timing and optimization resources, to more efficiently manage State Road Construction (SRC), non-SRC and operating budgets and to ensure consistency in signal timing and maximizing system signal performance throughout the State.

The Shared Services concept is an organizational approach that is focused on building efficiencies and reducing redundancies so that services can be provided on behalf of the entire organization. It is not intended to decrease MnDOT's compliment, but add value to the department's work by improving, innovating, integrating and streamlining work functions.

FY 2020 Signal Optimization Shared Service Projects

In FY 2020 Central Office Consultant Services Unit was granted $200,000 in consultant P/T contracts for the signal optimization program. In addition, TSMO provided an additional $150,000 to the signal optimization shared services program because it was determined that signal optimization was Strategy #1 of the TSMO implementation plan. Of this budgeted amount, the Metro Signal Operations Unit led six signal optimization projects with a total cost of $305,028.08.

FY 2020 was also notable because of the COVID-19 pandemic. As a direct result of the pandemic, five of the six signal optimization projects had to be deferred to FY 2021. The projects that were deferred to FY 2021 are outlined in the executive summary and include the consultant who is performing the signal optimization project, the project name, the total number of signals being re-timed, and approximately how much of the project was completed in FY 2020 and how much remains in FY 2021. Also, included in the table is the corresponding operational cost to the district for Metro's time to manage the Professional/Technical contracts for the projects.

In addition, the one project that was completed in FY 2020 is outlined in the executive summary (PDF) and includes the consultant who performed the signal optimization project, the project name, the total number of re-timed signals, the Measure of Effectiveness (MOE), the Benefit to Cost ratio (B/C) for each project, and the corresponding operational cost to the district for Metro’s time to manage the Professional/Technical contract for the project.
