Route-Based Driver Alerts That Avoid Repeated Black Spot Warnings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems repeatedly notify drivers of the same accident-prone locations, leading to driver discomfort and potential for increased accidents due to repetitive alerts.
Innovation Solution
An information providing system that includes a memory device storing accident-prone location information and history information, using processing circuitry to identify and notify drivers of unnotified locations based on their planned travel routes, thereby avoiding redundant alerts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the information processing device issues an alert message to the driver each time the vehicle approaches an accident black spot, then the driver is reminded of the spot, but the driver may feel uncomfortable due to repeated reminders of the same item
Solution Approach 1:
The system stores history information in advance indicating whether the driver has been notified of each accident-prone location. Before issuing alerts, the system checks this pre-stored history information to determine if the driver has already been notified, thereby avoiding repeated reminders and maintaining driver comfort while ensuring safety reminders are provided when necessary.
2Loss of information
If the system notifies the driver of all accident-prone locations on the route, then complete safety information is provided, but the driver receives redundant alerts for already-notified locations
Solution Approach 1:
The system extracts only the necessary notification information by comparing the planned travel route with stored history information. It identifies and notifies the driver only of accident-prone locations that have not been previously notified, thereby providing complete safety information without redundant alerts.
3Ease of operation
If the system tracks notification history for each driver, then repetitive notifications are avoided, but the system complexity increases
Solution Approach 1:
The system automatically manages notification history by storing and retrieving information indicating whether each driver has been notified of specific accident-prone locations. This self-service mechanism eliminates the need for manual tracking and simplifies notification management while maintaining necessary data records.

AI summary
An information providing system includes a memory device that stores accident-prone location information including items. Each of the items includes position information of a spot that requires attention of a driver and a precaution related to the spot. The processing circuitry is configured to store, in the memory device, history information indicating whether the driver has been notified of each of the items. The processing circuitry is configured to extract, based on the accident-prone location information, the history information, and the planned travel route, an item of which the driver has not been notified. The item corresponds to a spot included in the planned travel route. The processing circuitry is configured to notify the driver of the extracted item before the driver starts driving.
