Destination Previsualization for Accessible Route Planning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle navigation systems fail to provide passengers with adequate information about accessibility conditions at their destination, which can impact trip feasibility and user experience, particularly for individuals with specific needs.
Innovation Solution
A previsualization system that generates real-time images or video feeds of the destination, allowing users to assess accessibility features and make informed decisions before embarking on their trip, and can adjust routes based on user preferences and real-time updates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If real-time images and previsualization are provided to passengers, then accessibility information availability is improved, but system complexity and data processing requirements increase
Solution Approach 1:
The system performs preliminary actions by capturing images of the destination and generating previsualization content before the vehicle arrives. This allows accessibility information to be prepared and made available to passengers in advance, reducing last-minute information gaps without requiring complex real-time processing during travel.
Solution Approach 2:
The system creates visual copies (images and previsualization content) of the destination environment that can be displayed to passengers. These copies provide sufficient accessibility information without requiring passengers to physically visit or experience the destination firsthand, thereby information availability without proportional increases in system complexity.
2Adaptability or versatility
If multiple routing instructions and real-time updates are provided, then route adaptability is improved, but information processing load and communication requirements increase
Solution Approach 1:
The routing information is segmented into multiple discrete instructions and updates that can be processed and transmitted incrementally. Instead of providing all possible route information at once, the system divides guidance into manageable segments based on vehicle position and passenger needs, reducing information processing load while maintaining route adaptability.
Solution Approach 2:
The system implements dynamic routing where instructions and updates are adjusted in real-time based on vehicle location, passenger feedback, and changing destination conditions. This dynamic approach allows the system to provide only relevant information at each moment, optimizing adaptability while minimizing unnecessary information processing and communication overhead.
3Measurement precision
If comprehensive destination images and videos are captured, then visualization quality is improved, but data transmission and storage requirements increase
Solution Approach 1:
The system extracts only the essential visual information needed for accessibility assessment from comprehensive destination images and videos. Rather than transmitting or storing complete high-resolution media files, the system identifies and extracts key visual elements (such as entrance accessibility, pathway conditions, or facility features) that are sufficient for passenger decision-making, thereby maintaining visualization quality while reducing data requirements.

AI summary
A method for previsualizing a destination includes receiving, at a controller, a destination from a user. The controller retrieves a set of stored destination preferences and at least one image of the received destination. A route is generated to the received destination. A previsualization image of at least a portion of the route is generated and displayed to a user. The route is implemented using the controller in response to the user accepting the route.
