Intelligent Transformation in Urban Traffic Management: Zhengzhou's Exploration of "DeepSeek + Drone" Solutions
Zhengzhou integrates drones and AI (DeepSeek) to revolutionize traffic data collection, optimize signal timing, and alleviate congestion, combining smart management with expert-refined strategies for efficient urban mobility.
As cities continue to expand, traffic congestion has become a core challenge in urban governance. In Zhengzhou, explosive growth in vehicle flow has heightened the demand for intelligent traffic signal timing management. Amid profound transformations in smart transportation, DeepSeek, with its advanced semantic understanding, data mining, and intelligent decision-making capabilities, has been widely adopted in public services nationwide, offering innovative solutions for traffic management. With rapid technological advancements, cutting-edge tools like drones and AI are accelerating their integration across industries. Zhengzhou traffic police have resolutely embraced a technology-driven strategy, leveraging drones and AI to optimize traffic signal timing, elevate intelligent traffic management, and pioneer new pathways to alleviate urban congestion.
01 Data Collection Revolution: Drones Enable Precision Traffic Profiling
Traditional traffic data collection tools—microwave detectors, radar-video integrated systems, and loop detectors—face limitations such as restricted coverage and environmental interference. Drones have revolutionized this field. Their aerial perspective provides comprehensive, real-time traffic insights across broad areas.
With high mobility, drones swiftly reach target zones, filling data gaps in areas lacking ground equipment. For example, at the intersection of Huayuan Road and Hongkang Road in Zhengzhou, drones captured critical data on road width, lane configurations, and traffic flow, enabling precise vehicle volume analysis.
02 Intelligent Management: DeepSeek Boosts Traffic Efficiency
Zhengzhou traffic police have innovatively integrated **"drone + AI"** technology, with DeepSeek playing a pivotal role in optimizing traffic signal timing. By analyzing traffic flow data and dynamically adjusting signal phases, it maximizes intersection efficiency and addresses congestion.
Case 1: "Conflict Resolution" at Major Intersections
At Huayuan Road and Hongkang Road, DeepSeek enabled four-phase signal control optimization. Acting as an AI traffic commander, it allocated green-light durations based on real-time flow data, slashing vehicle wait times and enhancing throughput. Key outcomes:
Extended cycle time to 180 seconds (+10 seconds), reducing phase-switching delays.
Balanced queueing and minimized conflicts, lowering collision risks (see Figure 4).
Reduced saturation levels:
South-north left turn: **-11.1%**
East-west straight: **-4.5%**
East-west left turn: **-22.4%**
Case 2: "Coordinated Optimization" at Dual-Main-Road Intersections
At Huayuan Road and Sanquan Road—a critical dual-main-road junction—DeepSeek-driven optimization achieved:
19% increase in south-north straight traffic capacity.
34% surge in east-west left-turn efficiency.
Saturation reductions:
South entrance straight: **-12.3%**
East entrance left turn: **-10.8%**
These results underscore the power of DeepSeek + drone synergy in creating smoother, safer traffic flows.
03 Tech-Empowered & Expert-Driven: The "Dual-Helix" Evolution of Smart Traffic Management
While celebrating the success of **"DeepSeek + drone"** solutions, Zhengzhou traffic police maintain a balanced approach. Like the mutual reinforcement of DNA's double helix, smart traffic management requires both AI-driven insights and human expertise:
DeepSeek processes vast data to generate optimized plans.
Experts refine solutions by factoring in adjacent intersections, pedestrian behavior, illegal parking, and real-world complexities.
Next steps include:
Building a "drone + DeepSeek" virtual validation system** for signal timing.
Developing adaptive signal control platforms and citizen engagement channels (e.g., "Green Wave Experience Index"**) to collect feedback and enhance key corridors.
Conclusion
At Zhengzhou's optimized intersections, the arc of drone technology meets the rhythm of urban life. This fusion—cold algorithms understanding warm human needs—epitomizes intelligent traffic management's ultimate goal: safeguarding both efficiency and empathy. Zhengzhou traffic police will continue advancing tech-driven strategies, exploring innovations to deliver smarter, safer, and more efficient mobility for all.
