Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional photo-based traffic enforcement systems are inefficient, costly, and unable to automatically detect double parking violations, as they rely heavily on human reviewers and fail to consider contextual factors.
Innovation Solution
A computer-based system using edge devices with video image sensors and deep learning models to automatically detect double parking by determining road edges, lane layouts, and vehicle positions, and analyzing contextual features like brake light status and traffic conditions to determine if a vehicle is parked or moving.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional photo-based traffic enforcement systems are used, then human reviewers can validate evidence packages, but the process becomes slow, inefficient, and costly
Solution Approach 1:
The system enables automatic self-validation of parking violations through AI-powered image analysis. The evidence package validation is performed autonomously by the system itself using machine learning models to detect double parking violations, eliminating the need for external human reviewers while maintaining accuracy and improving processing speed.
Solution Approach 2:
The manual human review process is replaced with an automated computer vision system. The mechanical action of human reviewers examining evidence packages is substituted with electronic image processing algorithms that automatically analyze captured images, detect violations, and validate evidence packages without human intervention.
2Reliability
If human reviewers are used to validate evidence packages, then contextual factors can be considered, but large amounts of human effort are required
Solution Approach 1:
The system performs automatic contextual analysis and evidence validation without requiring human reviewers. The AI system independently evaluates contextual factors such as brake light status, traffic conditions, and vehicle positioning to determine violation reliability, replacing the need for human effort while maintaining or improving validation reliability.
Solution Approach 2:
An AI-based image analysis system serves as an intermediary between the captured evidence and the validation decision. This intermediary automatically extracts and evaluates contextual factors from images, providing reliable validation results without requiring direct human intervention in the analysis process.
3Quantity of substance
If photo-based enforcement systems are used, then evidence can be captured, but the systems fail to learn from past mistakes and adapt to new situations
Solution Approach 1:
The system incorporates feedback mechanisms where validation results and detected patterns are fed back into the training data for continuous model improvement. The AI system learns from validated violation cases and adjusts its detection algorithms accordingly, enabling the system to adapt to new violation patterns and improve accuracy over time based on accumulated evidence.
Solution Approach 2:
The system transitions from a static photo-capture approach to a dynamic learning system. The image analysis models are continuously updated and retrained based on validated evidence and new violation patterns, allowing the system to adapt its detection capabilities dynamically rather than relying on fixed, pre-programmed rules.

AI summary
Disclosed herein are methods, devices, and systems for automatically detecting double parking violations. For example, one aspect of the disclosure concerns a method comprising determining a location of a road edge of a roadway from one or more video frames of a video captured by one or more video image sensors of an edge device; determining a layout of one or more lanes of the roadway, including a no-parking lane, based on the road edge; bounding the no-parking lane using a lane bounding polygon; bounding a vehicle detected from the one or more video frames using a vehicle bounding polygon; and detecting a potential double parking violation based in part on an overlap of at least part of the vehicle bounding polygon with at least part of the lane bounding polygon and a determination of whether the vehicle is static or moving.
