Have you ever felt...
Suddenly plunging into the tunnel“Black Hole Effect”?
The stark contrast between the bright exterior light and the illuminated tunnel interior.
People instantly enter a "blind" state.
If congestion occurs ahead and there is insufficient time to maneuver around it.
Accident-prone
Once an accident occurs in the tunnel
High-speed traffic police need to be within the "blind box."
Identify the accident site, time-consuming and labor-intensive.
And the evacuation can only be conducted in the forward and backward directions.
Easy to trigger secondary accidents
Risk is significantly higher than on ordinary expressways.
Therefore, for traffic police,Act quickly, and even quicker.!
In Hang-Rui ExpresswayHyde Tunnel(Hangzhou Direction)
This "speed" is made possible by technology.
When an accident occurs in the tunnel
The accident site is "clearly visible."
Real-time automatic alarm capabilities
The time for police to respond to an emergency is now quickest within 5 seconds.
Processing time has also been reduced from the previous average of 10 minutes.
Enhanced to an average of 3 minutes

"Outside the Heyde Tunnel, the lanes consist of 2 regular lanes and 1 emergency lane. Inside the tunnel, there is no emergency lane. During high traffic periods, many vehicles occupy the emergency lane for driving, leading to congestion as they merge at the tunnel entrance."The Section Management Team's Captain TangThe 3.6 kilometers leading up to the Hyde Tunnel and the 2.1 kilometers within it are the "traffic congestion hotspots."During peak hours, every extra minute of congestion could potentially add over 200 more vehicles, stretching for over a kilometer, hence "traffic management" must be swift.。
In the past, the tunnels were like..."Black Box"Following the accident, law enforcement responses are typically initiated through the driver's report.The tunnel is an enclosed space, making it impossible to determine the exact location by referencing other buildings on the road surface. Relying solely on the driver's description, it is challenging to pinpoint the accident site. Moreover, the monitoring points are limited and do not cover the entire tunnel, requiring manual retrieval and review one by one. Additionally, the angle of view can create blind spots, even in non-tunnel areas. After a round of operations,It takes the police approximately 5-10 minutes to locate the bottleneck.Low accident response efficiency.
To minimize delays, during holidays, highway police officers maintain a presence every 500 meters, focusing on the 5.7-kilometer stretch of highway that includes the Hyder Tunnel.In order to facilitate quick patrols and handling of emergencies, corresponding police officers can respond promptly."Good luck might find it quickly, but bad luck could mean a lot of searching," said Team Leader Tang. "It might seem like just a few minutes of delay, but the potential consequences could be severe, so we're racing against time to ensure safety."

Applicable3D Holographic SystemLater on,The real traffic conditions of a 5.7-kilometer expressway have been replicated in a 1:1 scale on the traffic management command center's large screen, with the tunnel interiors also becoming real-time and crystal clear visible.Every vehicle on the large screen is a reflection of the real world, displaying the traffic conditions inside and outside the tunnel in real time, giving viewers the feeling of floating above the highway. In the event of an emergency, the system will automatically sound an alarm and locate the accident site, greatly enhancing the efficiency of blockage detection and management.

On February 16, 2024, at noon, a rear-end collision occurred at the Haidao Tunnel, where the rear vehicle caught fire upon impact. Fortunately, police officers arrived at the scene within two minutes and promptly extinguished the fire in its initial stage using a fire extinguisher. Recalling the incident, the officer still felt apprehensive, "This was more than just a traffic jam; the thought of cars burning in such a confined tunnel is unimaginable." The rapid, efficient, and precise handling of the accident relied on the 3D holographic system.Following a rear-end collision, the system instantly triggered an alarm, and police promptly viewed the accident location on the system. They immediately coordinated with nearby traffic police to arrive at the scene and extinguished the fire source.。
From human surveillance to system detection, the workload for traffic police has significantly decreased. "During holidays, we still have one officer patrolling every 500 meters, but now we can pinpoint traffic bottlenecks more accurately. This has lessened our mental pressure and given us more confidence," said Team Leader Tang.
Preventive Measures Taken Proactively
Technology aids in solving tunnel operation challenges
The formation of bottlenecks often stems from seemingly minor acts of disorder, such as lane changes within tunnels, serpentine driving, and pedestrians crossing at high-speed areas outside tunnels, as well as vehicles occupying emergency lanes.
Now, with our 3D holographic system, we can detect these irregular driving behaviors in real-time. This includes common violations such as illegal lane changes, occupying the emergency lane, and pedestrians entering the tunnel.The system's AI behavioral analysis module can automatically identify违规行为, and simultaneously push notifications to law enforcement terminals."Initially, during the crackdown, violations still occurred occasionally. However, as the system has continued to operate, more and more drivers have realized the importance of safe driving, resulting in a significant improvement in traffic order both inside and outside the tunnel."

In addition, key vehicles and improper driving behaviors can also be managed through the 3D holographic system. Staff can easily access detailed event information and view the distribution of surrounding equipment and law enforcement resources with a single click.Completed event review, scheduling, disposition, and feedback, forming an efficient closed-loop process. Complex issues that once required repeated communication and coordination can now be resolved appropriately within minutes with the assistance of the holographic system.



Under police protection and technological support, the smooth operation of the Haidai Tunnel has become the norm, not only representing an innovative achievement in the management of the Hangzhou-Ruihe Expressway, but also setting a precedent for tunnel management across the nation."Smart Prototype"Data shows that road tunnels are still growing at a rate of over 1,000 per year.
Under such circumstances, the practice of Hyder Tunnel has fully proven:Utilizing technology to enhance traffic management is one of the key approaches to solving tunnel operation challenges and improving safety and efficiency.A series of safe and smooth tunnels will become the "Digital Pathway" connecting cities to rural areas, warming the journeys of millions.
"Discover 1 second faster, solve it in 1 minute less, and you could potentially reduce 1 kilometer of traffic congestion, and even avoid secondary accidents." said Team Leader Tang. "During festive gatherings, the traffic around the Haidao Tunnel is at its peak. This system not only ensures the smooth flow of the highway but also guarantees the顺利 reunion of everyone."
