A reference point for Drone Video Sensing Analytics (DVSA) 

 

GoodVision is a traffic video analytics company that has carved out a distinct niche in the smart mobility and intelligent transportation systems (ITS) space. Their platform is designed to transform raw video footage—whether from fixed cameras, IP streams, or drone captures—into actionable traffic intelligence using advanced computer vision and deep learning. At its core, GoodVision’s technology replaces manual traffic data collection with automated, AI-powered interpretation, enabling urban planners, traffic engineers, and infrastructure managers to make data-driven decisions with speed and precision. 

 

The backbone of GoodVision’s analytics engine is a suite of deep learning models trained to detect, classify, and track vehicles and pedestrians across diverse environments. These models are optimized for real-world conditions, including varying lighting, weather, and camera angles. GoodVision supports footage from standard CCTV and IP cameras, including brands like Hikvision and Axis, as well as aerial drone footage captured at altitudes up to 250 meters. The system performs well even with relatively low-resolution inputs—down to 640×480 pixels at 10 frames per second—though higher resolutions and frame rates naturally yield better detection fidelity. 

 

The vision processing pipeline begins with object detection and classification. Vehicles are identified and categorized into types such as cars, trucks, buses, motorcycles, bicycles, and even custom classes like tuk-tuks or e-scooters. This is achieved using convolutional neural networks (CNNs) and feature aggregation techniques that allow the system to maintain high accuracy across diverse scenes. Once objects are detected, GoodVision applies tracking algorithms to follow their movement across frames. These trackers are robust to occlusions and erratic motion, enabling reliable trajectory extraction even in congested intersections or complex roundabouts. 

 

One of the standout features of GoodVision’s platform is its ability to compute behavioral and safety metrics directly from video. The system calculates Post-Encroachment Time (PET) and Time to Collision (TTC), which are critical indicators of near-miss events and traffic risk. These metrics are derived from trajectory intersections and velocity vectors, using temporal-spatial analysis to assess how close two objects came to colliding and how fast they were approaching each other. This capability allows cities to proactively identify dangerous intersections and implement safety improvements before accidents occur. 

 

GoodVision’s architecture is designed to balance edge and cloud processing. For real-time applications, such as live traffic monitoring and controller adjustment, the system can operate at the edge—processing video streams locally to minimize latency and bandwidth usage. This is particularly useful for smart intersections and adaptive traffic signal control, where decisions must be made in milliseconds. For more complex analytics, such as long-term traffic modeling or retrospective studies, the platform leverages cloud infrastructure to handle large-scale data ingestion, storage, and batch processing. Users can upload footage and receive processed results within hours, depending on video quality and system load. 

 

The platform also includes a user-friendly interface for project management, report generation, and stakeholder collaboration. Users can define virtual lines and zones within the video, extract counts and classifications, and export results in formats like Excel, CSV, or custom schemas. The system supports automated model calibration, reducing the need for manual parameter tuning and accelerating deployment across new sites. 

 

In GoodVision’s video analytics technology is a tightly integrated blend of deep learning, vision algorithms, and scalable infrastructure. Its ability to operate across edge and cloud environments, interpret diverse video inputs, and deliver high-resolution traffic insights makes it a compelling benchmark for any initiative aiming to build intelligent, real-time video analytics for mobility.
