Road Surveillance System Adaptive Notification Logic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing road surveillance systems face inefficiencies due to repeated notifications for persistent road abnormalities, leading to decreased operator efficiency as they continually confirm known issues.
Innovation Solution
A road surveillance system that includes image processing to detect road states and performs notification processing only when specific criteria are met, including a first criterion for road state detection and a second criterion related to the determination result, allowing for adaptive notification settings and change-related processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the data analysis server repeatedly determines and displays the same road abnormality event, then the determination result remains correct and reliable, but the operator efficiency decreases due to repeated confirmations of known issues
Solution Approach 1:
The system introduces a feedback mechanism where the operator terminal stores determination results and compares new detection results against stored ones. When a determination result matches a stored result, the system suppresses redundant notifications. This feedback loop maintains reliability by ensuring accurate detection while improving productivity by eliminating repetitive operator confirmations of the same abnormality.
Solution Approach 2:
The system changes the parameter of notification frequency based on the temporal characteristics of road abnormalities. By detecting whether an abnormality is persistent or transient and adjusting the notification behavior accordingly, the system maintains reliable detection of all abnormalities while reducing unnecessary repeated notifications, thereby improving operator efficiency without sacrificing detection accuracy.
2Loss of information
If the system notifies operators of all detected road abnormalities, then complete information is provided, but unnecessary notifications increase when the same abnormality persists over time
Solution Approach 1:
The operator terminal maintains a storage of determination results and uses this stored information to filter subsequent notifications. By comparing new detection results with stored results, the system ensures that only novel or changed abnormalities generate notifications. This feedback mechanism preserves information completeness by maintaining a record of all detected abnormalities while reducing notification volume by suppressing repetitions of the same persistent abnormality.
Solution Approach 2:
The system extracts and stores determination results separately from the notification process. By taking out the determination result storage function and using it to filter notifications, the system maintains complete information about all detected abnormalities in the storage while extracting only the necessary novel information for notification, thereby reducing notification volume without losing information completeness.

AI summary
To improve efficiency of road surveillance, a road surveillance system includes a detection unit 122 and a processing unit 134. The detection unit 122 detects a road state being a state of an object on a road by processing an image in which the road is captured. The processing unit 134 performs, when the road state satisfies a first criterion, any of notification processing of making a notification of the road state that satisfies the first criterion according to notification setting related to the notification, and change-related processing related to a change in the notification setting, based on whether a second criterion is satisfied. The second criterion is a criterion related to a determination result of whether the road state satisfies the first criterion.
