Vehicle-Mounted Device Filtering Irrelevant Roadside Traffic Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In road traffic information providing systems, vehicles often receive repetitive or irrelevant alarm information when entering the communication range of roadside apparatuses, burdening drivers with unnecessary information.
Innovation Solution
A road traffic information providing device that receives and stores alarm information, allowing users to control output via an operation unit, prioritizing information and stopping unnecessary or low-priority alerts, and registering irrelevant roadside apparatus IDs to prevent further information from those sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the ETC vehicle-mounted device receives alarm information from roadside apparatus every time it enters communication range, then the device ensures comprehensive information coverage, but the driver is burdened with repetitive and irrelevant alarm information
Solution Approach 1:
The system performs preliminary actions by storing alarm information when first received from roadside apparatus, and uses registration mechanisms to preemptively identify and block repetitive or irrelevant information before it reaches the driver, thus maintaining information coverage while preventing driver burden
Solution Approach 2:
The system implements feedback through the registration mechanism that tracks previously received alarm information and roadside apparatus IDs, continuously monitoring incoming information against registered data to intelligently filter out duplicates and irrelevant alerts, ensuring comprehensive coverage without repetition
2Loss of information
If the vehicle-mounted device outputs all received alarm information, then the driver receives complete traffic information, but irrelevant information such as outbound lane alerts for inbound lane vehicles is transmitted
Solution Approach 1:
The system extracts and separates relevant alarm information from irrelevant information by comparing received alerts against registered roadside apparatus IDs and vehicle lane data, removing harmful irrelevant information (such as outbound lane alerts for inbound vehicles) while preserving necessary traffic information
Solution Approach 2:
The system applies local quality by tailoring the information output to the specific context of the vehicle's current lane and location, ensuring that alarm information is filtered and customized according to the driver's actual needs rather than providing uniform information to all vehicles
3Object-affected harmful factors
If the system filters out repetitive alarm information, then driver burden is reduced, but the device complexity increases due to registration and filtering mechanisms
Solution Approach 1:
The system implements self-service through automatic registration of roadside apparatus IDs and autonomous filtering of alarm information based on pre-registered data, eliminating the need for manual intervention while reducing driver burden through intelligent, self-managing filtering mechanisms

AI summary
An utterance type road traffic information providing device (system) provided with a roadside apparatus (100) set on a road where a vehicle travels, at a parking lot or a place adjacent to the parking lot for transmitting alarm information by wireless communication, an utterance type vehicle-mounted device (200) mounted on a vehicle for receiving the alarm information from the roadside apparatus by wireless communication and outputting the alarm information, a administration server (300) that exchanges various information with the roadside apparatus (100). The utterance type vehicle-mounted device (200) is comprised of a predetermined operation unit and a control unit. The control unit cancels a part or all of the utterance voice output of the alarm information supplied from the roadside apparatus (100) in accordance with a predetermined operation of the operation unit. An output of the same alarm information or alarm information irrelevant to its own vehicle is prevented.
