Passenger Location System Using GPS Interval Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing passenger guidance systems using personal mobile information terminals require users to set message reception conditions each time, leading to reduced effectiveness and anxiety for passengers, especially in unfamiliar transportation areas or when unable to hear guidance information.
Innovation Solution
A passenger location information system utilizing a portable information terminal and server that determines the transportation line interval using GPS and station information, providing real-time location updates without prior condition setting, and offering customizable notification methods such as vibration or voice alerts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users set message reception conditions each time using personal mobile information terminals, then the system can provide guidance information, but the operation becomes complex and the effect is reduced significantly with repeated use
Solution Approach 1:
The system automatically determines the transportation line interval and provides guidance information without requiring users to manually set reception conditions. The portable information terminal autonomously acquires location information, determines the current interval, and receives appropriate guidance messages, eliminating the need for repeated manual configuration while maintaining reliable guidance effectiveness.
2Ease of operation
If automatic message notification is started without condition setting, then ease of operation is improved, but users may feel uneasy when unable to hear guidance information
Solution Approach 1:
The system dynamically adjusts notification methods based on the user's current situation and preferences. Instead of using a single fixed notification method, the system can select from multiple modes (visual display, auditory announcement, vibration alerts) and adapt them to the user's needs, ensuring reliable guidance information reception while maintaining ease of operation.
Solution Approach 2:
The system incorporates feedback mechanisms to ensure guidance information is effectively delivered. By monitoring user response and notification delivery status, the system can adjust its behavior to ensure users receive and understand guidance information, preventing feelings of unease when unable to hear messages while maintaining automatic operation.
3Reliability
If real-time location information is provided continuously, then user anxiety is reduced and guidance effectiveness is improved, but information overload may occur
Solution Approach 1:
Instead of providing continuous location information, the system uses periodic updates triggered by significant events such as approaching stations, changes in transportation line intervals, or predetermined time intervals. This periodic action maintains timely guidance information delivery while reducing information processing load and preventing overload.
Solution Approach 2:
The system provides location information with varying levels of detail based on the user's current situation and needs. When the user is in a critical location (near destination or transfer point), more detailed information is provided. In less critical areas, summarized information is given, optimizing the balance between timeliness and processing load.

AI summary
The present invention provides a passenger location information system that provides information on the current location of a user during a trip in real time and in a mode suitable for each user. A configuration is provided in which passenger location information, at least including information on the ends (station, stop, etc.) of a transportation line interval in which a portable information terminal is located, is output at a predetermined time on a user terminal 1 such as a mobile phone terminal connectable to a network. In addition, using notification means such as a ringing tone or a vibrator, the user terminal 1 notifies the user, under a condition set by the user in advance, that the user is approaching a destination to prevent the user from riding past a destination due to dozing.
