—The Urgent Need for Collision Prevention in Light of the Zhengzhou Double-Decker Bus Accident
On the morning of March 11, 2025, a Zhengzhou B12 double-decker bus mistakenly entered a side road with a height restriction of only 3 meters, resulting in a violent collision between the upper deck and the tunnel ceiling, shearing off the roof entirely. Fortunately, only one passenger sustained minor injuries. However, this incident exposed the critical shortcomings of traditional traffic management, which relies heavily on manual observation—driver distraction, unfamiliar routes, and delayed recognition of height restriction signs.
Such accidents are not isolated cases. Every year, numerous bridge and tunnel collisions occur worldwide due to vehicle height violations, highlighting the urgent need for technological innovation in collision prevention.
LSLiDAR LiDAR-Based Height Restriction Collision Avoidance System: Precise Sensing, Active Prevention, and Proactive Safety
To address such safety hazards, LSLiDAR has introduced a globally leading LiDAR-based Height Restriction Collision Avoidance System, integrating high-precision LiDAR sensors and AI algorithms to provide comprehensive safety solutions for urban traffic, logistics, and transportation sectors.
This intelligent system utilizes LiDAR’s active and high-precision detection capabilities to identify oversized vehicles approaching height-restricted areas in advance. It issues immediate audio-visual alerts, preventing collisions with height barriers, bridges, and tunnels. The system effectively redirects or stops oversized vehicles before accidents occur.
Key Advantages of LSLiDAR’s Height Restriction Collision Avoidance System
High-Precision LiDAR Technology
Utilizes high-speed scanning LiDAR with centimeter-level accuracy to rapidly scan vehicles, capturing dimensions (length, width, height) and generating a 3D environmental model.
Accurately calculates the distance and height difference between the vehicle and the restriction barrier.
Non-Stop Real-Time Detection
The system can detect oversized vehicles without requiring them to stop or slow down.
Multi-Level Warning Mechanism
The system supports audio and visual alerts. When an oversized vehicle is detected, the system immediately notifies the driver and can integrate with the vehicle’s control system to trigger deceleration or braking.
24/7 All-Weather Operation
Unaffected by lighting conditions, ensuring high detection accuracy even at night.
Adaptability to Complex Road Conditions
Suitable for various highways, tunnels, bridges, underpasses, and other complex road conditions.
Two Installation Solutions for Different Road Conditions
Solution 1: Pole Installation
Solution 2: Overhead Gantry Installation
Wide Application Scenarios: Enhancing Safety Across Multiple Sectors
The LSLiDAR LiDAR-Based Height Restriction Collision Avoidance System is not only applicable to urban roads and highways but also has broad applications in:
스마트 물류: Protecting unmanned forklifts, AGVs, and industrial vehicles from height-related collisions, preventing cargo damage and equipment loss.
Rail Transit: Detecting foreign objects on subway screen doors and monitoring track intrusions, ensuring safe train operations.
Special Environments: Managing height restrictions in ports, construction sites, and other complex settings, reducing operational risks.
Leveraging LiDAR Technology to Ensure Safer Journeys
The Zhengzhou double-decker bus accident serves as a stark reminder of traffic safety risks. Committed to the vision of “zero collisions”, LSLiDAR continues to advance LiDAR technology and AI algorithms, making height restriction collision avoidance lighter, more cost-effective, and widely accessible—empowering the development of smart cities with cutting-edge safety solutions.
