Polygonal Notification Region for Vehicle Operation Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle operation management systems cannot accurately set and notify entrance and exit of vehicles from complex geographical regions, such as those along a river, due to the limitation of using rectangular-shaped notification regions.
Innovation Solution
An operation management device and system that allows users to set a notification region as a polygonal shape by connecting multiple points on a map image, enabling accurate determination of vehicle position inclusion within the specified region and providing notifications accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a rectangular-shaped notification region is used, then the system structure is simple, but the region cannot conform to complex geographical shapes such as prefectural borders along a river
Solution Approach 1:
The notification region is divided into multiple vertices that can be independently positioned. By segmenting the region definition into discrete points (vertices) rather than requiring a continuous geometric shape, the system can represent complex geographical boundaries through a series of connected points, enabling adaptation to irregular shapes while maintaining manageable system complexity
Solution Approach 2:
The system changes the parameter of region definition from fixed geometric shapes (rectangles) to flexible vertex coordinates. By allowing users to specify regions through multiple coordinate points rather than simple dimensional parameters, the system gains the ability to represent any polygonal shape, including complex geographical boundaries
2Measurement precision
If a rectangular notification region is used, then the setting process is simple, but the accuracy of detecting vehicle entrance and exit from complex regions is poor
Solution Approach 1:
The region is segmented into multiple vertices that can be precisely positioned along the actual geographical boundary. This segmentation allows the notification region to closely follow complex boundaries such as river-based prefectural borders, significantly improving the accuracy of detecting when a vehicle enters or exits the region, while the automated vertex connection process maintains operational simplicity
Solution Approach 2:
The system transitions from defining regions in two dimensions (width and height of rectangles) to defining regions through multiple coordinate points in a polygonal framework. This dimensional approach allows precise representation of complex geographical shapes by specifying vertices along the actual boundary, improving detection accuracy while the system handles the complexity of connecting these points

AI summary
An operation management device including: a display control unit configured to display a map image on a user terminal; a storage configured to store a setting region, the setting region being specified as a polygonal shape which is formed by connecting three or more points set by a user of the user terminal on the map image displayed on the user terminal; an acquisition unit configured to acquire position information that indicates a position of a vehicle registered in advance, and a notification unit configured to notify the user terminal of a determination result of whether the position indicated by the position information is included in the setting region.
