Argumentsfor Cellular Vehicle-to-Everything (C-V2X): Delaying Adoption in India Could Be Costly
India is making significant strides in the implementation of Cellular Vehicle-to-Everything (C-V2X) technology, a short-range communication system that allows vehicles to exchange real-time data with other vehicles, road infrastructure, and pedestrians. This move is part of India's growing connected vehicle ecosystem, supported by the rollout of 5G technology and industry collaboration.
Current Status of C-V2X in India
The connected car market in India is expected to grow at an annual rate of 19.1%, driven by the adoption of C-V2X, 5G, and IoT-based telematics. Indian OEMs and Tier-1 suppliers are collaborating with telecom providers and semiconductor firms to develop scalable and secure C-V2X connectivity platforms. Infrastructure development, particularly the integration of private 5G and LTE networks, is also growing to support C-V2X's low latency and high reliability requirements.
Potential Benefits of Widespread C-V2X Adoption for Road Safety
The widespread adoption of C-V2X technology has the potential to significantly enhance road safety. Real-time exchange of vehicle location, speed, and trajectory data among vehicles reduces collisions and facilitates emergency vehicle movements. Vehicle-to-infrastructure (V2I) communication optimizes traffic flow via smart traffic signals, toll booth management, and lane guidance, reducing congestion and accident risks around infrastructure hotspots. Vehicle-to-pedestrian (V2P) connectivity through mobile apps alerts drivers of nearby pedestrians and allows safer crossing, especially in dense urban areas. Connection to wider networks (V2N) provides drivers with timely updates on adverse weather, accidents, or road conditions, improving awareness and preparedness. C-V2X also enables secure over-the-air (OTA) updates for continuously improving vehicle safety features and cybersecurity defenses against emerging threats.
Challenges in Widespread Adoption
Despite the potential benefits, the widespread adoption of C-V2X faces several challenges. Full benefits require robust 5G coverage and dedicated short-range communications infrastructure, which is still maturing across India, especially in rural and semi-urban regions. Ensuring uniform standards and compatibility among different manufacturers and telecom providers remains a complex challenge, as global standards continue to evolve. Investment in C-V2X capable hardware and network resources adds to vehicle and infrastructure costs, posing affordability challenges for mass-market adoption in India. With increasing connectedness, protecting user data and defending against cyberattacks demand stringent regulation, encryption, and real-time security monitoring systems. Educating drivers and pedestrians about C-V2X technologies and their interaction protocols is vital for maximizing safety benefits and minimizing misuse.
Focus on Two-Wheeler Safety
To make India's most vulnerable vehicles (two-wheelers) more visible, low-cost V2X transmitters could be installed on all new motorcycles. Two-wheelers account for nearly 45% of road deaths and over 28% of fatality-causing offences in India. India's two-wheeler ecosystem presents a unique mix of scale and vulnerability, making it a high-priority area for intervention. India could adapt V2I (Vehicle-to-Infrastructure) models from countries like the United States to suit its conditions, ensuring consistency, shared standards, uniform interfaces, and interoperable alerts across cities and states.
Looking Ahead
C-V2X technology offers Indian roads predictability and real-time awareness, with the goal of making roads more communicative, not just reactive. The idea of zero road fatalities, known as Vision Zero, is gaining traction in India, and could be adopted in a practical and scalable way to address its urgent safety challenges. Europe aims to eliminate road fatalities by 2050 and has set V2X as a key part of its plan. China has already pumped over $1.4 trillion into V2X infrastructure and has 20,000 roadside units active across 90+ cities. Mahindra is currently the only Indian automaker piloting V2X capabilities in its production vehicles. Bharat NCAP, launched in 2023, could award points for V2X in crash test programs, similar to what is done in other countries.
In summary, India is actively advancing C-V2X implementation as part of its connected vehicle ecosystem, supported by 5G expansion and automotive industry collaboration. The technology promises significant enhancements in road safety through real-time communication among vehicles, infrastructure, pedestrians, and networks. However, challenges related to infrastructure readiness, cost, security, and standardization need to be addressed for its widespread and effective deployment.
