Transit Visualization Route Segmentation and Interleaved Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Transit visualization systems face challenges in efficiently displaying and transmitting real-time information about multiple targets along routes due to bandwidth limitations and cluttered displays, which can lead to suboptimal user experience and increased data transmission requirements.
Innovation Solution
The system optimizes information transmission and display by decomposing routes into discrete segments, using interleaved patterns for shared segments and consistent display indicators, and employing data compression and dynamic rendering to minimize bandwidth usage and maintain clarity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all target route and position information is transmitted and displayed on the TVS display, then complete real-time tracking information is provided, but the display becomes cluttered and bandwidth requirements increase
Solution Approach 1:
The patent divides the route into multiple segments and uses different display patterns for different segments. Shared segments use an interleaved display pattern that alternates between routes, while non-shared segments use solid display patterns. This segmentation allows the system to display multiple routes without creating a cluttered appearance, as each segment type has its own optimized display characteristics.
Solution Approach 2:
The patent applies different display qualities to different portions of the same route information. Specifically, shared segments are displayed with an interleaved pattern (different visual quality) while non-shared segments are displayed with a solid pattern. This local differentiation allows the display to convey multiple routes clearly without uniform clutter across the entire display.
2Loss of information
If all target route and position information is transmitted and displayed on the TVS display, then complete real-time tracking information is provided, but bandwidth consumption increases
Solution Approach 1:
The patent merges the display of multiple routes into a single interleaved pattern for shared segments. Instead of transmitting and displaying separate information for each route on shared segments, the system combines them into one alternating pattern, reducing the total amount of data that needs to be transmitted while maintaining complete tracking information for all routes.
3Ease of operation
If multiple routes are displayed with consistent width, then visual clarity is improved, but the complexity of managing different route representations increases
Solution Approach 1:
The patent implements a dynamic display system where the visual representation of routes changes based on the segment type. The system automatically switches between interleaved patterns for shared segments and solid patterns for non-shared segments, maintaining consistent width throughout. This dynamic adaptation provides visual clarity without requiring manual management of different route representations.

AI summary
Route information for at least a first route and a second route is displayed using display indicators assigned to each route. The routes may be decomposed into discrete segments, some of which may be shared among the routes. Upon determining which segments are shared by routes, the shared segments may be displayed using an interleaved pattern of the display indicators associated with the routes. The interleaved pattern may comprise an alternating pattern of the display indicators associated with the routes. Non-shared segments may be displayed with the respective display indicators for the routes that use that segment. The width of the interleaved patterns may be substantially the same as the width of the non-shared segments. In one embodiment, the routes may be fixed. Targets associated with each route may be displayed on the routes.
