Founded in 1974 to manufacture axle-counting treadles, The Revenue Markets, Inc. (TRMI), also known as TRMI Systems Integration, designs, builds, installs, and maintains custom-integrated electronic toll collection systems. The family-owned company installed the nation’s first all solid-state toll collection system at the Golden Gate Bridge in 1981, and says its headquarters includes 30,000 square feet for system development, assembly, and production. Its work has since extended to toll facilities across the United States and overseas.
