US-based firm TransCore is to supply an electronic, radio frequency identification (RFID)-based payment system to the state of Utah.

The new payment system, a first for the state, will adjust toll pricing based on traffic conditions and replace the existing Interstate 15 Express Lanes decal system in the state.

The system will allow motorists to pay only for their actual lane usage as opposed to the fixed fee for a monthly decal.

The system uses a traffic-condition algorithm software, which collects traffic flow data from the express and general-purpose lanes and calculates a price that matches demand.

The $16m nine-year maintenance contract for the system has been awarded by the Utah department of transportation and includes the system design, installation, integration, Encompass 6 multiprotocol RFID readers and RFID-based eZGo Anywhere HOT/HOV transponders.

The system is scheduled to be installed towards the end of 2010.
