High-tech motorways: India uses NVIDIA-accelerated computing to ease traffic congestion at toll booths www.deekpay.com

## The congestion conundrum on India's motorways: how AI can help automate toll booths? India has the second largest highway network in the world, but its vast network of highways also brings huge traffic congestion problems. Traditional manual toll booths often lead to long waiting times and serious traffic delays, becoming a "roadblock" that impedes the smooth flow of roads. To solve this problem, NVIDIA Metropolis partner Calsoft is using vision AI applications to help automate toll booths on Indian highways. AI Enabled: Cracking the Licence Plate Recognition Challenge Automation of toll booths in India is challenged by the accuracy of the licence plate recognition (ANPR) system. The wide variety of licence plates in India, with different colours, sizes, font styles and locations, as well as the lack of a unified language standard, pose a huge challenge to the recognition system. Calsoft developed a solution that automatically reads the licence plates of passing vehicles and charges the driver's Unified Payment Interface (UPI) account, effectively reducing the need for manual toll collection. The key role of NVIDIA technology The solution utilises NVIDIA Metropolis for full vehicle tracking and detection, and NVIDIA Triton inference server software to deploy and manage AI models. To address challenges such as the difficulty of nighttime detection and environmental impacts, Calsoft also leveraged the NVIDIA DeepStream software development suite to build a real-time streaming platform and used hardware devices such as the NVIDIA Jetson Edge AI Module and NVIDIA Tensor Core GPUs. Automation is effective The solution has been piloted in several major cities in India and has achieved significant results. Using ANPR technology, licence plate reading accuracy reached 95%, effectively reducing traffic congestion. Looking Ahead Calsoft's toll booth solution is scalable and adaptable to future changes and developments in traffic conditions, providing a sustainable solution for automating India's highways. Conclusion Through the application of AI technology, India is gradually solving the problem of automation of highway toll booths, improving the efficiency of road traffic and improving the travelling experience of the people. This not only provides an effective solution for India's traffic development, but also provides new ideas for traffic management in other countries and regions around the world.
