Intersection Priority Control Using Path Change and Payment Points
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional technologies for managing vehicle priorities in intersections require manual determination for transferring priority status, which hinders autonomous driving operations.
Innovation Solution
An information management device that automatically changes travel paths and transfers corresponding points based on predetermined settings, using storage to hold user information and a processor to execute programs that determine path changes and payment points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual determination is used for transferring priority status, then flexibility in priority management is improved, but automation level deteriorates
Solution Approach 1:
The system enables autonomous vehicles to automatically determine and execute priority status transfers without human intervention. The vehicle control devices autonomously compare priority levels, detect intersection situations, and execute path changes based on predetermined rules, allowing the system to serve itself rather than requiring manual determination
Solution Approach 2:
The system changes the operational parameters from manual control to automated control by implementing algorithms that automatically compare priority information, detect intersection situations, and determine path changes. This parameter change enables the transition from flexible but manual operation to automated operation with consistent rule-based decision making
2Measurement precision
If manual action is required for priority transfer, then control precision is improved, but productivity deteriorates
Solution Approach 1:
The system enables continuous automated operation by eliminating manual intervention requirements. Vehicle control devices continuously monitor for intersection situations, automatically compare priority levels, and execute path changes without interruption, maintaining continuous useful action rather than pausing for manual determination
Solution Approach 2:
The system replaces manual mechanical action with automated electronic control. Instead of requiring human drivers to manually determine and execute priority transfers, the system uses electronic communication between vehicle control devices, automated comparison algorithms, and electronic path change execution, substituting the manual mechanical process with an automated electronic system that maintains precision while improving speed
3Productivity
If automated path change is implemented, then productivity is improved, but device complexity increases
Solution Approach 1:
The system reduces operational complexity by performing preliminary actions - vehicles pre-register their priority information and intersection preferences before reaching the intersection. This preliminary setup allows the automated system to make quick decisions based on pre-established criteria rather than complex real-time calculations, improving productivity while managing device complexity
Solution Approach 2:
The system segments the priority management function into distinct modules: priority information storage, intersection detection, priority comparison, and path change execution. This segmentation allows each component to be independently developed and tested, reducing overall system complexity while enabling automated high-productivity operation

AI summary
An information management device includes: a storage unit and a comparator unit. The storage unit stores setting information indicating stance and payable points; stance indicates whether a user boarding a host vehicle is to yield to a target vehicle or is to be given right of way by the target vehicle, when the travel paths of the vehicles intersect; the payable points are the upper limit of payment points to be paid to the user boarding the target vehicle when the target vehicle changes its path. The comparator unit refers to the setting information when a first traveling device of a first vehicle detects a second vehicle as the target vehicle, and compares the stance and the payable points of a first user boarding the first vehicle with those of a second user boarding the second vehicle, to determine the vehicle to change its travel path and the payment points.
