Mn/DOT began operation of the State's first HOT lanes on a segment of I-394 in the Minneapolis/St. Paul region on May 16, 2005, referred to as the MnPASS lanes. MnPASS refers to the tolling organization and the electronic tolling transponders. This system is also one of the first in the United States that dynamically adjusts pricing in response to varying traffic conditions. Recognizing the use of the I-394 MnPass deployment as a test bed for evaluating the viability of the HOT lane concept and the broad interest in the application, Mn/DOT implemented a comprehensive evaluation effort to assess the system.
The analysis revealed that violation rates on I-394 decreased following MnPASS (electronic tolling transponder) implementation.
- This was particularly evident in the HOV sections of the corridor where violation rates fell from 20 percent to 9 percent.
- During the same period, violations on I-35W, where MnPASS was not implemented, increased from 22 percent to 33 percent.
