Vehicle Navigation System Predicting Route Intersections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Emergency vehicles face delays and increased risk of accidents due to traffic congestion and drivers being unaware of their approach, as existing traffic management systems lack custom alerts for emergency vehicles and rely on precise vehicle locations.
Innovation Solution
A navigation system that predicts the geographical area where a non-priority vehicle will be within a specified time interval and generates warnings when the route of a priority vehicle intersects with this area, providing real-time notifications without requiring direct communication between vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traffic management applications rely on precise locations of vehicles using location syncing, then vehicle position accuracy is improved, but system complexity and data privacy requirements increase
Solution Approach 1:
The patent extracts only the essential information needed for traffic management - specifically, the geographical area boundaries and route intersections - rather than sharing complete precise location data. The system determines reachable geographical areas and checks for route intersections with emergency vehicles, providing sufficient alert functionality while minimizing data exchange and system complexity.
Solution Approach 2:
The patent introduces an intermediary computational layer that processes location data locally in each vehicle's navigation system. Instead of requiring continuous precise location syncing between vehicles, each system independently determines its reachable geographical areas and performs intersection checks, acting as a mediator that reduces direct vehicle-to-vehicle data dependency.
2Object-generated harmful factors
If emergency vehicles use sirens to alert drivers, then alert capability is improved, but reliability decreases due to distractions like music masking the sirens
Solution Approach 1:
The patent introduces a visual intermediary alert system through navigation displays that complements or replaces auditory sirens. The system provides visual warnings when route intersections are detected, creating an alternative communication channel that is not subject to masking by music or other auditory distractions, thereby improving alert reliability.
Solution Approach 2:
The patent substitutes the mechanical/acoustic siren system with an electronic visual alert system based on GPS data processing and display technology. This replacement eliminates the reliability issues associated with auditory masking while providing equivalent or superior alert capability through visual information presentation.
3Speed
If emergency vehicles navigate through congested areas, then response speed is improved, but safety decreases due to increased accident risk from unaware drivers
Solution Approach 1:
The patent implements preliminary action by providing advance warnings to drivers before emergency vehicles arrive. The system detects potential route intersections and alerts non-emergency vehicle drivers in advance, giving them time to prepare and move to the shoulder or emergency lane, thereby reducing accident risk while maintaining emergency vehicle speed through congested areas.
Solution Approach 2:
The patent establishes a feedback loop where the navigation systems continuously monitor and communicate the positions and routes of emergency vehicles to other vehicles. This real-time feedback enables drivers to adjust their behavior based on approaching emergency vehicles, improving safety without compromising the emergency vehicles' ability to maintain speed.

AI summary
Methods, systems and computer readable media are provided for traffic management between a first vehicle and a second vehicle. A navigation system of the second vehicle may receive position and route information describing a route that the first vehicle is projected to follow. The navigation system of the second vehicle may determine a geographical area, wherein the geographical area encompasses locations determined to be reachable by the second vehicle within a specified time interval. The navigation system of the second vehicle may generate a warning when the route of the first vehicle and the geographical area of the second vehicle intersect with each other.
