Public Transit Error Detection via Boarding Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing route guidance services for public transportation fail to promptly detect instances of users taking wrong transportation services, leading to delayed detection and increased geographical or temporal separation from the intended travel path.
Innovation Solution
A travel information providing method that uses a terminal device to acquire destination and current location information, determines the departure and boarding times, and identifies the transportation service based on operation schedules, to notify users if the service does not stop at their intended alighting location, utilizing sensors and communication protocols for accurate detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If GPS positioning information is used to detect wrong transportation services, then detection capability is provided, but detection timing is delayed and geographical separation increases
Solution Approach 1:
The system performs preliminary actions by acquiring transportation service identification information (such as beacon IDs) when the user is still at the boarding location or just boarding, before the user has traveled a significant distance. This allows the system to determine correctness early in the journey, preventing delayed detection and reducing both time loss and geographical separation from the intended destination.
2Measurement precision
If route guidance services monitor transportation services continuously, then detection accuracy improves, but system complexity and resource consumption increase
Solution Approach 1:
The system extracts only the essential identification information (transportation service ID, boarding location, departure time) at the critical moment of boarding, rather than continuously monitoring all travel parameters. This extraction approach maintains high detection accuracy by capturing the key data point while significantly reducing system complexity and resource consumption compared to continuous monitoring.
3Measurement precision
If the system acquires multiple pieces of information (position, time, speed, destination) to determine correctness, then determination accuracy improves, but information processing complexity increases
Solution Approach 1:
The system performs preliminary acquisition of all necessary information (transportation service ID, boarding location, departure time, and destination) at the boarding stage before the journey begins. By having this information ready in advance, the system can perform rapid correctness determination without needing to continuously process multiple data streams during travel, thus maintaining high determination accuracy while reducing real-time information processing complexity.

AI summary
A method for providing information concerning travel by public transportation to a user via a terminal device capable of acquiring a time and a position includes acquiring, from the terminal device, information indicating the user's alighting location, acquiring a departure time and a boarding location based on whether a traveling speed calculated from a first time and a first position and a second time and a second position acquired from the terminal device have exceeded a first threshold value, identifying a transportation service the user has boarded based on the departure time, the boarding location, and operation information, determining whether the identified transportation service stops at the alighting location acquired from the terminal device, and providing the user, via the terminal device, information indicating that this transportation service does not stop at the alighting location if it is determined that the transportation service does not stop at the alighting location.
