Toll Lane Controller with Cabinet (TLC)


Toll Lane Controller (TLC) is placed in the tunnel underneath the toll lane or in the booth. The principal task of TLC is to control the toll collection and all its peripherals. It is a mediator between TMS software and lane hardware.,It transmits information and data of all lane activities to the “Toll Management System (TMS)” and receives other control information and data from the TMS. TLC consists of lane computer, power protection blocks, and peripheral coordination circuitry. It acquires the lane data and transmits it to the server in real time. TLC also communicates with the toll plaza server via “Local Area Network (LAN)”.

All lanes operating data is stored in the local hard disk drive in the lane. The hard disk stores all necessary program tables (like ETC list, daily pass details, etc) and data in memory, to optimize the toll collection functionality.

Each transaction data collected from the lane peripherals is stored in the local hard disk of the TLC in a separate encrypted file placed in a folder automatically created with the month’s name at the start of each month, before being transmitted to the master database in the TMS.

This data remains in the local hard disk irrespective of transmission to the TMS until a period of 3 months. At the start of the 4th month, the 1st month’s data is deleted from the hard disk on the basis of FIFO logic. The TLC is capable of communicating with the TMS. Communication consists of data necessary to build a complete database in the TMS, from which the required financial and operating reports and statistics can be generated.
