Barrier-Free Tolling Begins on the Tambaram-Tindivanam Stretch
On October 1, the National Highways Authority of India (NHAI) activated a barrier-free toll collection system at the Paranur toll plaza on National Highway 45, near Chengalpattu. The new setup allows vehicles to travel through the tolling zone without stopping at a booth, making Paranur the first toll plaza in Tamil Nadu to use Multi-Lane Free Flow (MLFF) technology.
Technology and Operation
The system combines FASTag-linked radio-frequency identification with Automatic Number Plate Recognition (ANPR) cameras. As a vehicle enters the tolling zone, overhead equipment reads the FASTag and captures the registration number. The data are matched to the vehicle’s account, and the applicable fee is deducted automatically. A functional FASTag with sufficient balance is required; NHAI has indicated that electronic notices will be issued for insufficient balances, invalid tags, or non-functional tags.
Official Rationale and Expected Benefits
NHAI states that the barrier-free arrangement is intended to improve traffic flow, cut fuel consumption, and lower vehicular emissions by eliminating idle time at toll booths. The authority also highlights reduced manual intervention, which should make transactions more efficient and transparent. By removing the need for drivers to queue in designated lanes, the system aims to shorten travel times along the 46.5-km Tambaram-Tindivanam stretch.
Broader Rollout and Impact
Paranur’s implementation follows earlier deployments of barrier-free tolling in Gujarat, Delhi, Haryana, and Rajasthan, and it follows the country’s first such plaza on the Kamrej-Choryasi stretch between Surat and Bharuch, which became operational earlier this year on the Mumbai-Delhi corridor (NH 48). NHAI has announced plans to extend the technology to additional locations in Tamil Nadu, Andhra Pradesh, and other states, signaling a nationwide shift toward fully automated toll collection on Indian highways.
