The Multi-Lane Free Flow (MLFF) tolling system at the Mundka-Bakkarwala fee plaza on Delhi's Urban Extension Road-II (UER-II) corridor became operational on May 11, 2026. One month later, the deployment is providing a real-world demonstration of how barrier-less tolling can support high-volume traffic movement while enabling automated, technology-driven toll operations at scale.
During its first month of operations, the corridor processed 1.6 million vehicle transactions, averaging more than 53,500 vehicles per day across a traffic mix of 80% passenger vehicles and 20% heavy vehicles. The uninterrupted flow of vehicles through the corridor is estimated to have saved 144,702 litres of fuel and prevented approximately 364 tonnes of CO₂ emissions.
Supported by Bosch Mobility Platform & Solutions in partnership with IDFC FIRST Bank, the project was commissioned by Indian Highways Management Company Ltd. (IHMCL) under the Ministry of Road Transport & Highways and the National Highways Authority of India (NHAI).
The barrier-less system enables electronic toll collection without requiring vehicles to stop at toll barriers, replacing conventional barrier-based toll plazas with a digital tolling zone where toll transactions are identified, validated, and processed in real time while vehicles pass through at highway speeds.
Delivering barrier-less tolling at highway speeds requires multiple technologies to work together simultaneously.
The Mundka-Bakkarwala deployment integrates:
At the core of the deployment is Bosch's Vehicle Correlation Service (VCS), a multi-sensor event processing engine that combines inputs from these different technologies into a single vehicle passage record.
This integrated approach helps ensure that tolling events are accurately identified, correlated, and processed across multiple sensing technologies
The Mundka site includes 16 MLFF-enabled lanes, comprising 12 active lanes and 4 backup lanes designed to support continuous tolling operations across varying traffic volumes.
The system maintains a digital audit trail for every vehicle transaction, with end-to-end event processing completed in under two seconds. This enables tolling and enforcement functions to be executed through a unified digital workflow while maintaining transaction traceability.
Performance indicators reported during the initial phase of operations included:
As highway networks continue to expand and traffic volumes increase, barrier-less tolling is expected to play an increasingly important role in enabling efficient corridor management and supporting the evolution of digital highway infrastructure.
The UER-II deployment demonstrates how technology-led collaboration can support the adoption of digital highway infrastructure, while enabling automated toll processing and greater operational visibility for highway operators.
Bosch Mobility Platform & Solutions remains focused on developing and deploying technologies that support operational efficiency, sustainability, and the continued evolution of connected mobility infrastructure.
