The "Road Smooth Guardian" system is the culmination of years of dedicated research and development by KJT, embodying the team's accumulated expertise in intelligent sensing, data fusion, and proactive early warning within the sensor field. From project initiation, research and development, design, and iteration, to solution demonstration, manufacturing, and final installation, it fully demonstrates KJT's strong capabilities in independent innovation and project implementation, and also highlights the company's unwavering commitment to safeguarding road safety through technology.
"Road Smooth Guardian" System Introduction
The "Road Smooth Guardian" system is a proactive early warning and safety assurance system for highways. Integrating advanced technologies such as the Internet of Things, cloud computing, 5G communication, big data analytics, and artificial intelligence, this system provides timely and accurate early warning information to road users and management through real-time monitoring of highway safety barriers and the surrounding environment, thereby reducing accident rates, casualties, and economic losses.
Main functions of the "Road Smooth Guardian" system
Intelligent Early Warning System: Issues an alert immediately after a traffic accident, notifying following vehicles to slow down or detour, reducing the risk of secondary accidents.
Road, Bridge Collapse, and Landslide Early Warning: Through geological and displacement monitoring equipment, once anomalies are detected in roads, bridges, or mountainous sections, an alert is immediately sent to the monitoring center and passing vehicles to ensure driving safety.
Construction and Maintenance Area Early Warning: Flashing red/yellow lights in construction and maintenance areas warn following vehicles in advance.
Severe Weather Early Warning: Combines meteorological sensors to monitor fog, heavy rain, snow, etc., and issues safe driving reminders.
SOS One-Click Alarm Function: In emergencies, drivers can quickly send a distress signal to the monitoring center using a one-click alarm function.
Precise Location and Efficient Response: Through cameras and a cloud platform, the system coordinates with drones and roadside assistance vehicles to respond to accidents promptly and handle them efficiently.
Intelligent Fog Light Warning: Intelligent fog lights automatically activate in low-visibility conditions such as dense fog, enhancing visibility and providing early warning.
LED Message Board Linked Warning: The system can link with highway LED message boards to instantly publish accident information, reminding following vehicles to slow down and avoid the area, effectively preventing secondary accidents.
"Road Safety Guardian" System Objectives
Improve Road Safety: Through real-time monitoring and precise early warning, the system detects risks such as accidents, landslides, and extreme weather in advance, and uses intelligent fog lights to improve driving safety in low visibility conditions.
Reduce Economic Losses: Prevent secondary accidents and traffic congestion, reducing losses caused by vehicle damage and delays.
Improve Emergency Response Efficiency: Provides immediate warnings after an accident occurs and quickly transmits information to management and rescue departments, accelerating the response time.
Facilitating Smart Transportation: The system can seamlessly integrate with existing traffic management platforms, promoting the construction of smart highways and intelligent connected transportation.
KJT's "Road Smooth Guardian" system effectively improves road safety, reduces accident losses, and accelerates emergency response by integrating intelligent monitoring, early warning technologies, and traffic management systems. It also provides solid support for the development of intelligent transportation and is an important practice in promoting the intelligent and safe advancement of modern highways.
