Emergency Routing System Optimizing Response Time
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current routing systems for public safety vehicles lack the necessary information to optimize response time, particularly in emergency situations, as they do not account for non-traditional paths, dynamically changing traffic conditions, or the capabilities of the responding units, leading to potential delays and inefficiencies.
Innovation Solution
The integration of traditional and non-traditional map data, including alternate routes and real-time information, using computer software like PCAD to determine the optimal route for emergency response and evacuation, considering the capabilities and requirements of the units and terrain, and dynamically updating this information for real-time decision-making.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If traditional routing systems use standard map data and speed limit information, then the route planning is simple and fast, but the response time is not optimized because emergency vehicles can ignore speed limits and use alternate paths
Solution Approach 1:
The patent segments the routing information into traditional map data and non-traditional map data (alternate routes, shortcuts, terrain information). This segmentation allows the system to process different types of routing information separately and combine them to optimize emergency vehicle routes without overwhelming complexity
Solution Approach 2:
The system pre-processes and stores multiple routing options including alternate paths and non-traditional routes before emergency situations occur. This preliminary action enables rapid selection of optimal routes during emergencies without requiring complex real-time calculations
2Speed
If the routing system uses only the shortest distance route, then the route is easy to determine, but it may not be the fastest route for emergency vehicles that can ignore speed limits and use alternate paths
Solution Approach 1:
The patent merges traditional map data with non-traditional map data including alternate routes, shortcuts, and terrain information. This combination creates a comprehensive routing system that provides emergency vehicles with multiple path options beyond standard speed-limit-based routes
Solution Approach 2:
The system changes the routing parameters from speed-limit-compliant navigation to emergency vehicle optimization. It incorporates parameters such as vehicle capability, terrain suitability, and alternate path availability to determine optimal routes that maximize speed for emergency vehicles
3Loss of time
If the system provides detailed routing information for multiple alternate paths, then the response time can be optimized, but the information processing and decision-making becomes more complex
Solution Approach 1:
The system incorporates real-time feedback mechanisms that monitor vehicle position, traffic conditions, and route progress. This feedback enables dynamic route adjustments and automated selection of the best path, reducing the operational burden on emergency personnel while optimizing response time
4Productivity
If the routing system only provides information for the dispatcher, then the system is simple to operate, but it does not enable the responding unit to independently determine the optimal route
Solution Approach 1:
The patent creates a universal routing system that serves multiple functions: it provides route information to both dispatchers and responding units, supports real-time communication between them, and enables independent route determination by the responding unit. This multi-functionality improves response efficiency without requiring separate systems

AI summary
Method and systems of improving the response of public safety personnel to or evacuation from a desired location are provided. In addition to path information obtained through traditional sources, information is used to determine the optimal route for emergency personnel to an emergency situation and for aiding emergency personnel to route people from the situation. The information may also be used to automatically prioritize vehicles and personnel to optimize response time. Further, the information may also be used to in situations in which it is advantageous for the vehicle or personnel to be tactically positioned in nearby locations rather than at the incident scene. Although the descriptions below will primarily focus on routes to a particular location, similar methods can be used for evacuations from the location. The optimal route may use historical information stored in a database local or remote to the dispatcher and/or real-time information updated during the emergency situation.
