On the evening of April 20, 2025, a highway in Uttar Pradesh, India, was the scene of a tragic accident caused by a driver’s illegal speeding and improper lane changes, resulting in six deaths and two injuries and temporarily bringing traffic to a standstill for several hours.

1. Current Situation of the Problem: Severe Road Safety Challenges: According to reports by The Times of India, the BBC, and other media outlets, India experiences frequent traffic accidents, with over 172,000 fatalities in 2023—averaging one death every three minutes.
2. Strategic Response: The government is implementing the “5E Strategy”: To address this crisis, the Indian government has launched the “5E Strategy,” aiming to reduce road accidents by 50% by 2030 by prioritizing the deployment of AI-powered video analytics, intelligent safety technologies, and smart transportation systems.
3. Implementation Approach: Integrated Deployment of Radar and AI Video: Currently, the government is rolling out integrated radar-and-AI video surveillance systems along the Delhi–Mumbai Expressway and in cities such as Lucknow, with roadside radar regarded as a critical technological enabler for efficient law enforcement and optimized road infrastructure management.
 

Customer Pain Points
The drawbacks of point monitoring are becoming increasingly apparent: Traditional speed cameras require single-lane deployment and only support fixed, localized monitoring of small areas; multi-lane coverage is costly and struggles to meet India’s demand for vehicle-type-specific enforcement across diverse traffic compositions.
Significant controversy over law enforcement evidence collection: Manual handheld radar speed guns used for roadside enforcement suffer from significant measurement errors, result in extremely low capture rates for speeding violations, and are prone to disputes and corruption due to human oversight; moreover, they cannot support 24/7, full-road-section automated enforcement.
Poor management and slow response: Frequent lane-cutting, lane-changing, and overtaking by vehicles, coupled with the mixed operation of vehicles traveling at different speeds, exacerbate congestion. In addition, the lack of reliable, systematic real-time traffic-flow data results in prolonged accident-response times and insufficient emergency-response capabilities.
 

Breakthrough: MR76S Radar Primary Drive + Visual Auxiliary Wing Fusion

Implementation of radar-based technology
(1) System Architecture:
Perception Layer: Leveraging radar–vision fusion technology that integrates the MR76S radar with an 8-megapixel high-definition camera, coupled with a processing unit, regulated power supply, and supplemental lighting system, this layer enables all-weather lane detection, precise data capture, and license plate recognition.
Network Transport Layer: After front-end data is aggregated by switches, it is transmitted over industrial-grade fiber optic transceivers to establish a stable link, effectively addressing latency and signal attenuation over long distances and ensuring high-speed data backhaul.
Platform Application Layer: Deploy an integrated traffic violation management system to enable core functions such as real-time monitoring, speed enforcement by vehicle type, motorcycle helmet recognition, and management and analysis of violation data.

(2) Equipment Installation:
Installation method: gantry-mounted (front-mounted) or roadside-mounted; recommended mounting height: 3–6 meters; downward tilt angle: 0–10°; orientation: directly facing the roadway.

Deployment Efficiency: Installation and commissioning of the complete single-point system takes only 2 hours, with virtually no impact on traffic.
Radar 3D coverage angle: The radar employs simultaneous operation of both long- and short-range dual beams, achieving a balance between detection range and detection accuracy. The blind-zone range is approximately 10–20 meters and dynamically adjusts with changes in altitude and elevation angle.

Core Product: MR76S Millimeter-Wave Radar

The MR76S is the latest compact millimeter-wave radar launched by Hunan Nalai Technology Co., Ltd. This product incorporates several cutting-edge technologies, including phased-array technology, DBF digital beamforming, MIMO virtual aperture, and near- and far-field beam shaping.
By emitting millimeter waves forward and analyzing their reflections, the system can determine the relative distance, velocity, and angle of obstacles, enabling real-time detection and tracking of both large and small vehicles as well as electric bicycles on the road.
 

Core Advantages:
Compliant and reliable: Operates in the 77 GHz frequency band, is CE-certified, complies with Indian radio regulations, and is a non-controversial enforcement tool.
High-precision interval speed measurement: Maintains real-time speed output within a 300-meter range, effectively preventing sudden braking to evade inspections, with minimal speed-measurement error and enhanced enforcement impartiality.
Multi-lane coverage: A single radar unit can provide coverage of six traffic lanes and track up to 128 targets, supporting both front-mounted and side-mounted configurations, with easy deployment and low total cost.
High capture rate: Strong angular resolution capability ensures a 98% vehicle detection rate at 100 meters, thereby reducing the false-negative rate for violating vehicles.
Minimalist Integration: Compact size and lightweight, with support for CAN and UART communication interfaces for easy integration.

Customer Benefits
Cost Reduction and Efficiency Improvement: A single set of equipment can support monitoring across up to six lanes, reducing equipment procurement costs by 30%. Maintenance personnel can perform fine-tuning and parameter calibration on-site at the roadside, lowering subsequent operation and maintenance expenses by 40%. Furthermore, round-the-clock automated supervision has replaced traditional manual inspections, boosting management efficiency by 50%.
Precise Control: The system provides real-time monitoring of key vehicle data such as vehicle type and speed, and allows for customized, differentiated speeding thresholds tailored to more than eight vehicle types. It achieves a compliance enforcement capture rate of 98%, with traffic volume data reflecting road congestion in real time and enabling the dynamic display of guidance information on electronic signs to redirect traffic flow, resulting in a 35% reduction in road congestion.
Enhancing Government Credibility: The video, photographic, and data records generated by the system carry legal weight, with a 100% compliance rate for admissibility as evidence of violations, thereby effectively reducing enforcement disputes and opportunities for corruption.

Figure 4: Real-Time Monitoring on the Client Software Platform

As shown in the figure above, the local traffic management authority can use the integrated management platform to automatically capture images of vehicles exceeding the speed limit and record vehicle information such as license plate number, vehicle type, and speed, thereby establishing a comprehensive and complete chain of evidence.
