Route Summary Truncation for Transit Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional on-demand transportation-network systems face challenges in accurately and efficiently presenting multi-leg route options due to limited screen space, often resulting in inaccurate, confusing, or incomplete depictions and comparisons, as well as inflexible parameter reliance.
Innovation Solution
A route-summary-truncation system that determines transit routes and generates shortened graphical summaries by performing segment-level and summary-level truncation operations, preserving important information and presenting it within a graphical user interface, using segment graphics and truncation operations such as removing characters or collapsing alternative route segments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional systems display all route legs to provide complete route information, then information completeness is improved, but screen space consumption increases and display clarity deteriorates
Solution Approach 1:
The patent applies segmentation by dividing the route summary into multiple hierarchical levels: expanded view showing all route legs, condensed view showing only key segments, and intermediate views. This allows the system to adapt the level of detail displayed based on screen space availability, maintaining information completeness when space permits while providing condensed representations when space is limited.
Solution Approach 2:
The patent implements dynamic adjustment of route summary detail by detecting screen dimensions and automatically selecting between expanded and condensed display modes. The system dynamically modifies the number of route legs displayed, the level of detail for each segment, and the inclusion of transfer information based on the available screen real estate, resolving the contradiction between information completeness and screen space utilization.
2Area of stationary object
If conventional systems omit route details to fit screen constraints, then screen space efficiency is improved, but route depiction accuracy deteriorates
Solution Approach 1:
The patent applies local quality by selectively maintaining high detail for critical route segments (such as transfer points and key destinations) while condensing or omitting less critical segments. This ensures that accuracy is preserved where it matters most for user decision-making, while screen space is conserved by reducing detail in less important areas.
Solution Approach 2:
The patent implements partial action by displaying a selective subset of route legs in condensed mode, focusing on the most essential segments that users need to know. Rather than attempting to display all segments with equal detail, the system applies partial action by showing only the critical portions, maintaining sufficient accuracy for route understanding while fitting screen constraints.
3Loss of information
If conventional systems display maximum route legs for all options to ensure completeness, then information completeness is improved, but comparison efficiency deteriorates
Solution Approach 1:
The patent applies dynamic adjustment by automatically selecting between condensed and expanded display modes for each route option based on screen space and user interaction. In condensed mode, only essential route characteristics are shown to enable quick comparison, while expanded mode provides complete details when users need to evaluate specific options in depth, thereby improving overall comparison efficiency.
Solution Approach 2:
The patent segments route information into hierarchical levels of detail, allowing users to quickly compare routes at a high level in condensed mode, then drill down into specific route options to view complete leg-by-leg breakdowns. This segmentation enables efficient initial comparison while preserving access to complete information when needed.
4Device complexity
If conventional systems use rigid parameter sets to generate route options, then system simplicity is improved, but route option relevance deteriorates
Solution Approach 1:
The patent implements dynamic parameter selection by adjusting route generation and display parameters based on detected screen dimensions, user preferences, and route characteristics. The system dynamically modifies which parameters are emphasized, the level of detail displayed, and the selection criteria for route options, thereby improving relevance without requiring a completely complex parameter system.
Solution Approach 2:
The patent applies parameter changes by modifying display parameters (such as number of legs shown, level of detail, inclusion of transfer information) based on screen size and user interaction. The system changes parameters dynamically to optimize route presentation for different contexts, improving adaptability and relevance while building upon a relatively simple base parameter set.

AI summary
The present disclosure relates to systems, non-transitory computer readable media, and methods for determining a transit route to a destination and generating a shortened graphical summary of the transit route to present on a computing device. For instance, in some cases, a system determines a transit route by which transit vehicles transport a user along route segments to a destination. The system further generates or configures a graphical route summary that includes segment graphics representing route segments from the transit route. To shorten the graphical route summary to fit within a graphical user interface, the system can successively perform one or both of (i) segment-level-truncation operations on individual segment graphics and (ii) summary-level-truncation operations on the graphical route summary. The system can further present a truncated graphical route summary in the graphical user interface based on one or both the segment-level-truncation operations and the summary-level-truncation operations.
