Adaptive Route Search System for Dynamic Movement Restrictions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing route searching systems fail to adequately search for routes when movement restrictions are individually set, particularly during specific time periods or in proximity to organizational bases, leading to potential exclusion of relevant roads and increased traffic congestion.
Innovation Solution
A route searching system that includes a storage unit for map and movement restriction information, a location recognition unit, and a route searching unit capable of determining movement conditions and searching for routes that either avoid or include movement restrictions based on the departure and destination locations, using map information that excludes or includes restricted regions as necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If movement restriction regions are adopted as passage-prohibited zones to restrict movement, then traffic congestion near organizational bases is reduced, but routes that are necessary during specific time periods cannot be found
Solution Approach 1:
The patent applies dynamics by making the route search adaptive to changing conditions. The system dynamically adjusts route search behavior based on the current time relative to restricted time periods. When the current time is within a restricted time period, the system prohibits entry into movement restriction regions. When the current time is outside restricted time periods, the system allows entry. This temporal dynamic enables the system to satisfy movement restrictions during restricted periods while maintaining route search flexibility during non-restricted periods, resolving the contradiction between traffic congestion reduction and route adaptability.
2Reliability
If roads within movement restriction regions are excluded from search candidates, then movement restrictions are enforced, but legitimate routes that pass through restricted regions during allowed times are missed
Solution Approach 1:
The patent applies parameter changes by modifying the route search parameters based on the current time. The system changes the status of roads within movement restriction regions from prohibited to allowed, or vice versa, depending on whether the current time falls within a restricted time period. This parameter change enables the system to maintain reliable movement restriction compliance during restricted periods while preserving route search efficiency and finding legitimate routes during non-restricted periods, thus resolving the contradiction between restriction enforcement and search productivity.
3Object-affected harmful factors
If a fixed movement restriction region is set to prevent traffic congestion, then organizational base vicinity is protected, but individual movement needs cannot be accommodated
Solution Approach 1:
The patent applies periodic action by implementing movement restrictions that are activated only during specific time periods rather than continuously. The system sets restricted time periods for each movement restriction region, and the route search behavior periodically changes based on whether the current time falls within these restricted periods. This periodic approach allows the system to protect the organizational base vicinity from traffic congestion during restricted periods while accommodating individual movement freedom during non-restricted periods, resolving the contradiction between congestion prevention and movement ease.

AI summary
A route searching system is provided that can appropriately search for a route even when a movement restriction is individually set. In a case where a movement condition is satisfied, the route searching system refers to movement restriction information and searches for a recommended route based on the map information so as to exclude a route that violates the movement restriction. In a case where the movement condition is not satisfied, the route searching system searches for a recommended route based on map information including a route that violates the movement restriction.
