Display Apparatus for Traffic Sensor Accuracy Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Infrastructure sensors used for traffic monitoring face challenges in accurately detecting vehicles, making it difficult to confirm detection accuracy, especially when the angle of installation is not correctly adjusted.
Innovation Solution
A display apparatus and computer program that display both the traffic volume detected by the infrastructure sensor and reference information from a different means, allowing users to compare and confirm detection accuracy, with features like image recognition and user-input counting to validate the number of vehicles detected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If infrastructure sensor is used for traffic monitoring, then traffic volume detection is achieved, but detection accuracy cannot be confirmed
Solution Approach 1:
The patent introduces a display apparatus as an intermediary that receives detection data from the infrastructure sensor and presents it alongside reference information from alternative sources. This mediator enables accuracy verification without requiring the sensor itself to self-validate, resolving the contradiction by providing an external reference mechanism.
Solution Approach 2:
The system implements feedback by displaying detected traffic volume alongside reference information and allowing users to compare the two. This feedback loop enables continuous verification of detection accuracy, transforming the one-way detection process into a verifiable bidirectional comparison that confirms reliability.
2Ease of operation
If infrastructure sensor detection data is displayed alone, then simple display is achieved, but user cannot verify detection accuracy
Solution Approach 1:
The patent merges the infrastructure sensor detection data with reference information from alternative sources into a unified display interface. This combination allows users to view both the sensor output and verification reference simultaneously, maintaining ease of operation while enabling accuracy verification through integrated presentation.
Solution Approach 2:
The display is segmented into distinct portions: one for displaying infrastructure sensor detection results and another for displaying reference information. This segmentation organizes the complex verification process into manageable visual sections, making it easy for users to understand and compare different data sources without overwhelming complexity.
3Reliability
If multiple means of traffic volume detection are used, then detection accuracy can be verified, but system complexity increases
Solution Approach 1:
The display apparatus serves multiple functions: it displays infrastructure sensor data, presents reference information from alternative sources, and provides a comparison interface for verification. This multi-functionality consolidates what would otherwise require separate systems into a single versatile device, reducing overall system complexity while enabling accurate verification.

AI summary
A display apparatus includes a first result display portion configured to display a first traffic volume detected by an infrastructure sensor configured to detect vehicles in a measurement area, and a second result display portion configured to display reference information indicating a second traffic volume obtained by a means different from the infrastructure sensor during a same period as a period during which the infrastructure sensor detects the first traffic volume.
