Traffic Congestion Detection

Traffic Congestion Detection

Algorithm Introduction
Algorithm Introduction
The traffic congestion detection algorithm primarily performs the following functions:

  • ● Vehicle Density Analysis: Counts road vehicle population and calculates density metrics per unit area or length.
  • ● Speed Monitoring: Tracks vehicle movement speeds to identify congestion thresholds (e.g., speeds below 20km/h).
  • ● Stagnation Detection: Identifies vehicles experiencing prolonged stillness (e.g., stationary for over 1 minute).
  • ● Congestion Level Classification: Grades congestion severity (light/moderate/severe) based on composite metrics including vehicle density, speed, and stagnation duration.
  • ● Real-time Alerting: Transmits congestion warnings to traffic management centers with location and severity details.
  • ● Data Visualization: Provides real-time congestion hotspot mapping to support traffic dispatching decisions."

FAQ

  • Algorithm Accuracy
    All algorithms published on the website claim accuracies above 90 %. However, real-world performance drops can occur for the following reasons:
    (1) Poor imaging quality, such as
    • Strong light, backlight, nighttime, rain, snow, or fog degrading image quality
    • Low resolution, motion blur, lens contamination, compression artifacts, or sensor noise
    • Targets being partially or fully occluded (common in object detection, tracking, and pose estimation)
    (2) The website provides two broad classes of algorithms: general-purpose and long-tail (rare scenes, uncommon object categories, or insufficient training data). Long-tail algorithms typically exhibit weaker generalization.
    (3) Accuracy is not guaranteed in boundary or extreme scenarios.
  • Deployment & Inference
    We offer multiple deployment formats—Models, Applets and SDKs.
    Compatibility has been verified with more than ten domestic chip vendors, including Huawei Ascend, Iluvatar, and Denglin, ensuring full support for China-made CPUs, GPUs, and NPUs to meet high-grade IT innovation requirements.
    For each hardware configuration, we select and deploy a high-accuracy model whose parameter count is optimally matched to the available compute power.
  • How to Customize an Algorithm
    All algorithms showcased on the website come with ready-to-use models and corresponding application examples. If you need further optimization or customization, choose one of the following paths:
    (1) Standard Customization (highest accuracy, longer lead time)
    Requirements discussion → collect valid data (≥1 000 images or ≥100 video clips from your scenario) → custom algorithm development & deployment → acceptance testing
    (2) Rapid Implementation (Monolith:https://monolith.sensefoundry.cn/)
    Monolith provides an intuitive, web-based interface that requires no deep AI expertise. In as little as 30 minutes you can upload data, leverage smart annotation, train, and deploy a high-performance vision model end-to-end—dramatically shortening the algorithm production cycle.
