Route Search System Mode Switching Conditions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing route search systems fail to adequately consider switching between multiple transportation modes, often leading to infeasible routes due to inappropriate transfer instructions and lack of condition settings for mode switching, particularly when walking is involved.
Innovation Solution
A route search system that acquires link information for various transportation modes, sets conditions for switching between modes based on a combination of transfer means, and uses this information to find a recommended route that connects links for different transportation modes, preventing infeasible routes by specifying valid switching points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a route search is performed assuming transfer with switching between multiple transfer means (walking, private car, bus, railroad), then the route search capability is improved, but infeasible routes may be generated due to inappropriate transfer instructions and lack of condition settings for mode switching
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting switching conditions based on the combination of transfer means. Different transfer mean combinations have different switching conditions (e.g., walking-railroad vs. private car-railroad). The system changes the parameters of switching conditions to match the specific transfer means combination, preventing infeasible routes while maintaining versatile route search capability.
Solution Approach 2:
The patent introduces switching conditions as an intermediary element between the route search function and the actual transfer execution. These switching conditions act as a mediator that filters and validates transfer instructions, ensuring that only feasible transfers are recommended. The switching conditions include criteria such as whether the current transfer means can actually reach the transfer point, preventing infeasible route recommendations.
2Reliability
If switching conditions are set based on transfer mean combinations, then route feasibility is improved, but the system complexity increases due to multiple condition settings
Solution Approach 1:
The patent segments the switching conditions into distinct components based on transfer mean combinations. Each transfer means combination (e.g., walking-railroad, private car-bus) has its own specific switching conditions. This segmentation allows the system to manage complexity by breaking down the overall condition setting into smaller, manageable segments rather than creating one complex universal condition set.
Solution Approach 2:
The patent applies partial action by implementing switching conditions only where necessary for specific transfer mean combinations, rather than applying uniform conditions to all transfers. The system selectively applies condition settings based on the actual transfer scenario, avoiding unnecessary complexity in situations where simple transfer instructions suffice.
3Productivity
If transfer points are selected without considering actual walking distance, then the route search speed is improved, but the appropriateness of transfer instructions deteriorates
Solution Approach 1:
The patent applies preliminary action by pre-calculating and storing switching conditions including walking distance thresholds before the actual route search. The system prepares condition data in advance that includes appropriate walking distance limits for different transfer scenarios. During route search, these pre-prepared conditions are quickly applied, maintaining search speed while ensuring transfer appropriateness through pre-validated walking distance criteria.

AI summary
Route search systems, methods, and programs search for a recommended route for transfer with switching between a plurality of transportation modes. The systems, methods, and programs acquire link information for specifying a link for transfer by each of the plurality of transportation modes and connection information related to connection between links for transfer by different transportation modes, and set a condition for switching from a first transportation mode to a second transportation mode, which is different from the first transportation mode, on the basis of a combination of the first transportation mode and the second transportation mode. The systems, methods, and programs search for the recommended route for transfer with switching between the plurality of transportation modes on the basis of the link information, the connection information, and the set condition, the recommended route connecting links for transfer by different transportation modes.
