Researchers at the National Institute of Technology (NIT) Rourkela have been granted a patent for an innovative model designed to drastically improve the reliability of future vehicle-to-vehicle communication networks. The patented technology addresses the critical challenge of message congestion in high-traffic scenarios, paving the way for safer, smarter road systems in India.

The patent, titled ‘Adaptive Contention Window Optimisation in VANETs using Multi-Agent Deep Reinforcement Learning for Enhanced Performance Model,’ was filed by Dr. Arun Kumar, Assistant Professor; Prof. Bibhudatta Sahoo, Professor and Dr. Lopamudra Hota, Research Graduate, all from the Department of Computer Science & Engineering at NIT Rourkela.

Their work focuses on Vehicular Ad-Hoc Networks (VANETs) – the foundational concept that enables vehicles in close proximity to communicate directly with one another. VANETs are essential for future functionalities like warning drivers about sudden obstacles or precipitous braking, aiding automated traffic control and assisting emergency services.

However, a core issue in VANETs is overcrowding. When multiple vehicles transmit messages simultaneously, the congestion leads to delays or lost messages, which severely compromises the system's ability to function safely.

The NIT Rourkela solution tackles this problem using artificial intelligence (AI). Their model employs multi-agent deep reinforcement learning to enable each vehicle to intelligently stagger the timing of its messages based on the real-time actions of other vehicles in the network. Instead of communications competing and colliding, the system learns to sequence and prioritise time-sensitive alerts, such as emergency warnings. This adaptive adjustment significantly reduces transmission delays, ensuring critical alerts are reliably delivered.

Dr. Arun Kumar highlighted the profound safety implications of their research, referencing the severe toll of road accidents in the country. “In 2023, India reported around 480,000 road accidents and around 172,000 deaths, many of which could be prevented using modern technologies. Our work is a step towards building safer roads and smarter cities. We envision a near future where autonomous vehicles become a reality in India, and this patent is a small step in that direction, driving the spirit of Innovate in India and Make in India,” Dr. Kumar said.

The developed model ensures that even under busy conditions, the right message reaches the right recipient at the right time, a crucial requirement for future transportation systems where vehicles must coordinate in real-time.

The enhanced communication model has broad applications across future mobility. Current VANETs use cases include:

• Electronic brake lights: Notifying drivers of braking scenarios not yet in their line of sight.
• Platooning: Enabling a series of cars to closely follow a lead vehicle using distributed acceleration and steering control data.
• Enhanced Navigation: Providing instantaneous, accurate information on current road traffic conditions.
• Emergency Response: Rapid broadcast of crucial information to vehicles in an area affected by an incident.
• Electronic Toll Collection: Providing remote access to real-time data for automated toll systems.

Prof. Bibhudatta Sahoo emphasised the practical impact of the work on national infrastructure. “The patent represents a practical step towards preparing India's road system for vehicle-to-vehicle communication. By addressing potential congestion in VANETs and providing a model for adoptive, coordinated communication, the findings lay the groundwork for safer and a more efficient traffic management. We invite researchers across institutions to join our efforts in making future autonomous vehicles and collaborate with our research lab at NIT Rourkela,” said Prof Sahoo.

CARS24, in partnership with CrashFree India and the Bengaluru Traffic Police, has launched India’s first AI-powered road safety billboard that displays traffic challans in real time. This initiative transforms technology into a highly visible public reminder – safer roads start with accountability.

Located at Trinity Circle, one of Bengaluru's busiest intersections, the AI-enabled system instantly scans vehicle number plates. In seconds, it cross-references the data with the government's VAHAN database and flashes the results onto a large LED screen.

The screen displays details of:

• Pending traffic challans
• Expired vehicle insurance
• Lapsed Pollution Under Control (PUC) certificates
• Crucially, fully compliant vehicles are also acknowledged, reinforcing positive driving behaviour.

The company shared that reaction on the streets has been immediate and undeniable. Motorists have been seen looking up sheepishly when their fines are displayed, while others smile in relief at an ‘all clear’ message. For bystanders, it's become a spectacle, making it clear that responsibility is no longer hidden in an SMS or buried in an app.

One commuter remarked, “This feels like going back to school. When your name got called out in class, you paid attention. Now, when your challan shows up on that giant screen, you know you can’t escape it."

This innovative approach directly confronts India's mounting INR 120 billion challan crisis, which includes nearly INR 90 billion in unpaid fines. Bengaluru alone recorded 8.29 million violations last year.

The AI billboard doesn't issue new penalties; instead, it makes existing violations and lapses impossible to overlook.

Gajendra Jangid, Co-Founder & CMO, CARS24, said, “We are not just reminding people to clear challans or update documents. We’re reminding them that every act of responsibility on the road, no matter how small, is what keeps an entire city alive. Safety doesn’t come from systems alone; it comes from choices. And the road is the one place where your choices instantly touch thousands of lives.”

A senior official from the Bengaluru Traffic Police echoed this sentiment: “This is not about shame, but awareness. Discipline starts with visibility. If this board helps even a fraction of drivers become more responsible, it’s a win for the city.”

The installation at Trinity Circle is a pilot project. If successful, this blend of technology and visibility could be scaled to other high-density junctions in major cities across India. The goal is to reduce violations, increase timely challan payments and most importantly, make India's roads significantly safer.

In a move to address one of the key challenges facing the electric vehicle industry, automotive supplier Valeo and French engineering school Arts et Métiers are expanding their strategic partnership to focus on quieting electric powertrains.

After a successful seven-year collaboration, the two organisations are launching a new industrial research chair dedicated to the ‘vibro-acoustics of electric powertrains.’ The goal is to develop innovative solutions to manage and reduce the distinctive, high-pitched noise often associated with electric motors and gearboxes.

While the silent nature of electric vehicles is a major selling point, residual noises from the powertrain can be unpleasant for passengers and undermine this key benefit.

Christophe Giraud-Audine, a Professor-Researcher at Arts et Métiers, said, "These distinctive high-pitched noises, easily detected by human ears and unpleasant for the passengers, undermine one of the key qualities customers value: the silence."

Valeo's Noise and Vibration Master Expert, Herve Mahe, explained that reducing this noise requires a blend of electrical and mechanical expertise. The new chair will build on the previous collaboration, which successfully transformed fundamental research into practical industrial innovations.

Olivier Thomas, the Professor-Researcher who initiated the partnership, said, "Acoustic comfort has become a critical success factor for electric vehicles." He added that if the noise, vibration, and harshness (NVH) levels are too high, it could jeopardise customer acceptance of electric vehicles.

The new partnership, which will continue until 2032, will see teams from both organisations combine their expertise to find solutions. Researchers will apply their knowledge in digital computation, experimental design, vibratory mechanics and electrical engineering. In turn, Valeo will provide market insights and its own testing, calculation and design methods.

The research will focus on two main areas:

• Prediction: Developing new simulation tools to anticipate vibrations and noise early in the design phase.
• Action: Proposing new electrical control solutions and innovative methods for active or passive noise and vibration reduction, using materials like piezoelectric absorbers and meta-materials.

The program also includes plans for at least six PhD theses, one post-doctoral project, the recruitment of a research engineer, and various educational and scientific outreach initiatives.

By working together, Valeo and Arts et Métiers aim to strengthen Valeo’s leadership in electric mobility by ensuring that silence remains a core promise of the electric vehicle experience.
