The State of the Commute report is created each year to fulfill a mandate in the TransNet Ordinance. TransNet is the half-cent sales tax for local transportation projects that was first approved by voters in 1988 and extended in 2004 for another 40 years. TransNet funds numerous transit, highway, freight, bikeway, and walkway programs, in addition to an environmental conservation program, transit fare subsidies, and grants. The TransNet Independent Taxpayer Oversight Committee (ITOC) is responsible for ensuring all voter mandates are carried out. In response to the FY 2018 TransNet Triennial Performance Audit, this report also captures performance outcome data related to safety metrics, pavement, and bridge conditions, local roadways, and bike and pedestrian modes.

Custom reports can be created by the user to capture data relevant to specified criteria such as Jurisdiction, Location, or Annual or Quarterly reports by date.
