Emergency Response Re-routing System for Traffic Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current navigation systems do not re-route vehicles in response to emergency events, such as 911 situations, nor do they consider passenger- or vehicle-specific information to redirect resources like medical personnel or vehicles with specific properties to emergency scenes.
Innovation Solution
A system that integrates GPS receivers with an emergency dispatch system and vehicle registry to monitor emergency events, re-route vehicles with appropriate resources to emergency scenes, and divert others away to maintain traffic flow, using real-time information and vehicle-specific data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If navigation systems re-route vehicles to avoid congested areas, then traffic flow is improved, but emergency response time deteriorates because emergency vehicles are not prioritized
Solution Approach 1:
The system applies different routing priorities to different vehicles based on their function. Emergency vehicles receive preferential treatment with optimized routing that prioritizes speed to destination, while regular vehicles are routed around emergencies. This local differentiation resolves the contradiction by improving overall traffic flow for non-emergency vehicles while ensuring emergency vehicles achieve fastest possible response times.
Solution Approach 2:
The system continuously monitors vehicle locations, emergency statuses, and traffic conditions, then dynamically adjusts routing recommendations. When an emergency is detected, the system provides real-time feedback to emergency vehicles to route directly to the scene while diverting regular traffic. This feedback mechanism ensures both traffic flow management and emergency response prioritization are maintained simultaneously.
2Productivity
If navigation systems monitor and respond to emergency events, then emergency response efficiency is improved, but system complexity increases due to integration requirements
Solution Approach 1:
The navigation system is designed to perform multiple functions: routine navigation, emergency detection, emergency vehicle identification, dynamic routing, and traffic management. By making the system universal and multi-functional, the patent avoids the need for separate specialized systems, thereby improving emergency response efficiency without proportionally increasing overall system complexity.
Solution Approach 2:
The system automatically detects emergencies through integrated sensors and data sources, identifies emergency vehicles based on vehicle registry information, and dynamically adjusts routing without requiring manual intervention. This self-service capability improves emergency response efficiency while minimizing the operational complexity that would arise from manual system management.
3Productivity
If vehicles are diverted away from emergency scenes, then traffic flow is maintained, but response time for non-emergency vehicles deteriorates
Solution Approach 1:
The system pre-identifies alternative routes for non-emergency vehicles before they reach emergency zones. By calculating and preparing diversion routes in advance based on predicted emergency locations and traffic patterns, the system maintains smooth traffic flow while minimizing the time non-emergency vehicles spend navigating complex diversion scenarios.
Data Source
AI summary
Emergency response re-routing is provided. Event information is received, wherein the event information identifies a first location. Emergency resources available at the first location are determined. At least one entity in an area surrounding the first location is identified. A notification is issued to at least one entity in an area surrounding the first location, wherein the notification identifies one or more resources required at the first location.
