Route Search Device Using Section Priority Tables
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing route search devices struggle to select the most suitable transportation means for each section of a route to a destination, as they primarily rely on route length and surroundings, neglecting the attributes of start and end points, which can lead to suboptimal choices, especially when changing transportation modes.
Innovation Solution
A route search device and medium that prioritize transportation means based on attributes of start and end points for each section, using a priority table to set preferences for walking and other modes like private automobiles, trains, and buses, allowing for multimodal route planning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If route search relies only on route length and surroundings, then the search process is simple, but the selection of transportation means becomes suboptimal
Solution Approach 1:
The route is divided into multiple sections, with each section evaluated independently using priority tables. This segmentation allows the system to consider start point and end point attributes for each section without overwhelming complexity, enabling precise transportation means selection for each segment while maintaining manageable processing requirements.
Solution Approach 2:
Different priority tables are created for different transportation means (walking, private automobile, train, bus) based on local characteristics of start and end points. Each section of the route receives customized priority settings according to its specific attributes, such as whether the start point is a station or parking lot, enabling optimized selection without uniform complexity across the entire route.
2Adaptability or versatility
If only one transportation means is selected, then the route search is straightforward, but the route may not be suitable for distant destinations
Solution Approach 1:
The system dynamically selects and switches between different transportation means for different sections of the route based on priority tables. Instead of fixing a single transportation mode, the route search adapts by choosing the most appropriate means for each section (e.g., train for long-distance sections, walking for final destination approach), providing versatility for distant destinations while managing complexity through structured priority-based decision-making.
Solution Approach 2:
The priority table system serves multiple functions: it evaluates different transportation means, considers various start point and end point attributes, and optimizes route selection across different distance ranges. This universal approach handles both short and distant destinations effectively by applying the same framework with different priority settings, avoiding the need for separate specialized systems.
3Ease of operation
If transportation means are selected based on general route characteristics, then the selection process is simple, but it fails to account for specific section attributes like station or parking lot locations
Solution Approach 1:
Priority tables are pre-configured with appropriate weights for different transportation means based on start point and end point attributes (e.g., higher priority for walking when end point is a station, higher priority for private automobile when start point is a parking lot). This preliminary setup enables the system to automatically make reliable selections during route search without requiring complex real-time calculations, maintaining ease of operation while improving suitability.

AI summary
Provided is a route search device and a non-transitory computer-readable medium that can search a route where a transportation means more suitable for a user is selected. When searching a route to a destination, a change point at which the transportation means is changed is set, and then the priority in selecting a transportation means for moving in a section from a plurality kinds of transportation means is set based on at least one of an attribute of a start point and an attribute of an end point in the section for each section where a distance between a departure place and a destination is divided at the change point to search the route to the destination using the transportation means selected for each of the plurality of sections based on the set priority.
