Multi-modal Navigation System with Automatic Route Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current navigation systems are inadequate for handling multi-modal transportation routes, requiring users to input multiple destination addresses and lacking automatic determination of non-navigation related information such as timetables and train lines, which complicates travel using multiple modes of transport.
Innovation Solution
A method and system for generating and updating navigation routes across multiple modes of transportation, utilizing GPS data and non-route information like timetables and cost data, which allows for seamless transitions between transport modes and outputs instructions on both in-vehicle and nomadic devices via Bluetooth, WiFi, or cellular connections, based on events like key-off or proximity changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If users manually input multiple destination addresses for each transport mode, then route information can be obtained, but the operation complexity increases and user convenience deteriorates
Solution Approach 1:
The navigation system automatically determines multi-modal routes by integrating GPS data, transport mode information, and timetable data without requiring manual input of multiple destination addresses. The system self-updates the route based on detected transport mode changes, eliminating the need for users to repeatedly input addresses for each transport segment.
Solution Approach 2:
The system integrates multiple functions into a single navigation process: it handles GPS tracking, automatic route determination across different transport modes, timetable information retrieval, and real-time route updates. This multi-functional approach allows the system to manage complete multi-modal journeys through a single interface rather than requiring separate operations for each transport mode.
2Productivity
If the system integrates multiple transport modes with automatic route determination, then navigation efficiency improves, but the device complexity increases
Solution Approach 1:
The patent combines GPS data processing, transport mode detection, timetable information retrieval, and route calculation into a unified navigation system. The system merges data from multiple sources (GPS receiver, transport information databases, timetable data) and processes them through an integrated route determination algorithm that automatically generates multi-modal navigation instructions.
Solution Approach 2:
The system employs an intermediary processing layer that receives raw GPS data and transport mode information, then translates these inputs into coordinated navigation instructions across multiple transport modes. This intermediary layer manages the complexity by abstracting the integration details from the user interface, presenting a simplified view while handling complex multi-modal coordination internally.
3Measurement precision
If the system provides real-time route updates based on transport mode changes, then navigation accuracy improves, but the information processing requirements increase
Solution Approach 1:
The system performs route updates periodically based on detected transport mode changes rather than continuously processing all possible variables. The GPS receiver and transport mode detector trigger route recalculations at specific intervals or events (mode transitions), reducing unnecessary processing while maintaining accuracy when it matters most.
Solution Approach 2:
The system pre-loads and caches timetable information and transport mode data before they are needed for route calculation. By having this information readily available in memory rather than retrieving it in real-time during route updates, the system reduces processing energy requirements while maintaining the ability to provide accurate real-time route adjustments.

AI summary
One or more embodiments may include a multi-modal navigation system and method. Route information may be received for generating a navigation route which may comprise multiple modes of transportation to a destination. GPS data may also be received. The navigation route to the destination across the multiple modes of transportation may be determined. The route may be updated as the route is traversed. The navigation route across the multiple modes of transportation may be output based on the GPS data.
