Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional systems for detecting vehicles that illegally pass a stopped school bus require labor-intensive manual review of video footage, making it costly and inefficient for widespread deployment.
Innovation Solution
A computer-implemented method and system that automatically detects and tags moving vehicles passing a stopped school bus by analyzing video sequences from a camera mounted on the bus, using video segmentation, frame analysis, and automated license plate recognition to generate a violation package for law enforcement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual review of video footage is used to detect vehicles passing a stopped school bus, then detection accuracy is maintained, but processing time and costs increase substantially
Solution Approach 1:
The video sequence is partitioned into multiple video segments based on temporal information, where each segment corresponds to a specific bus stop event. This segmentation allows the system to focus analysis on relevant portions of the video, reducing overall processing time while maintaining detection accuracy for violation events.
Solution Approach 2:
The system extracts and tags only the specific frames and video segments that contain moving vehicles during bus stops, separating these from the rest of the video data. This extraction approach enables automated identification of violation evidence without requiring manual review of entire video sequences, significantly reducing processing time while preserving detection accuracy.
2Measurement precision
If manual review of video footage is used to detect vehicles passing a stopped school bus, then accurate identification of violations is achieved, but labor costs and operational complexity increase
Solution Approach 1:
The system performs self-service by automatically analyzing video segments, detecting moving vehicles, and generating tagged frames with violation evidence without human intervention. The automated processing pipeline includes video segmentation, frame analysis, and generation of violation packages, eliminating the need for manual review while maintaining accurate violation identification.
Solution Approach 2:
The manual mechanical review process is replaced with an automated computer vision system that uses algorithms to detect moving vehicles in video frames. This substitution eliminates human labor while maintaining or improving detection accuracy, and the system automatically generates structured violation packages for enforcement.
3Reliability
If comprehensive video recording is implemented for all bus stops, then complete violation detection capability is achieved, but data processing burden and costs become prohibitive
Solution Approach 1:
The system performs preliminary actions by automatically segmenting video sequences into bus stop events and pre-identifying frames containing moving vehicles before final violation determination. This preliminary processing organizes the data structure in advance, enabling efficient retrieval and review of only relevant violation evidence, thereby maintaining complete detection capability while improving processing efficiency.
Solution Approach 2:
Instead of requiring complete manual review of all video footage, the system applies partial action by automatically processing and tagging only the specific frames and segments that contain potential violations. This selective processing approach maintains reliable violation detection capability while dramatically improving processing efficiency by focusing computational resources on relevant data portions.

AI summary
As set forth herein, systems and methods are described that facilitate to analyze a video stream from a camera mounted on the side of a school bus, wherein a sub-set of video sequences showing cars illegally passing the stopped school bus are automatically identified through image and/or video processing. The described systems and methods provide a significant savings in terms of the amount of manual review that is required to identify such violations. The video sequences also can be analyzed further to additionally produce images of the license plate (for identification of the violator), thereby providing further reduction in required human processing and review time. In one embodiment, automatic license plate recognition (ALPR) is employed to identify text on the violator's license plate, as well as the state by which the license plate was issued, without requiring human review of the license plate image.
