Emergency Vehicle Route Prediction and Notification System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Emergency vehicles often face delays due to non-emergency vehicles not yielding in time, as drivers typically respond reactively to emergency vehicle lights and sirens only when close, leading to inefficient navigation in heavy traffic and challenging road conditions.
Innovation Solution
A system that includes an in-vehicle computing system in emergency vehicles and cloud servers to report and predict routes, allowing non-emergency vehicles to receive route information and alternative paths to avoid intersections with emergency vehicles, thereby enabling premeditated reactions and reducing delays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If emergency vehicles use lights and sirens to alert non-emergency vehicles, then non-emergency drivers can detect the emergency vehicle, but the detection occurs too late for timely lane changes and yielding
Solution Approach 1:
The system performs preliminary action by notifying non-emergency vehicles of approaching emergency vehicles before the emergency vehicle is visually or audibly detected. The cloud server receives route information from emergency vehicles and proactively sends notifications to affected non-emergency vehicles, allowing them to prepare for lane changes or yielding in advance, thus resolving the contradiction between detection distance and response time.
2Reliability
If emergency vehicles wait for non-emergency vehicles to yield, then safety is maintained, but emergency vehicle response time increases significantly
Solution Approach 1:
The system implements feedback by continuously monitoring emergency vehicle routes and communicating with non-emergency vehicles along those routes. The cloud server receives real-time route data from emergency vehicles and sends notifications to non-emergency vehicles, creating a feedback loop that enables coordinated yielding behavior while maintaining safety, thus resolving the contradiction between safety and emergency vehicle speed.
3Device complexity
If non-emergency vehicles respond reactively to emergency vehicle lights and sirens, then the system remains simple, but coordination efficiency is poor in heavy traffic
Solution Approach 1:
The system introduces an intermediary element - the cloud server - that mediates communication between emergency vehicles and non-emergency vehicles. Instead of direct interaction requiring complex vehicle-to-vehicle coordination systems, the cloud server receives route information from emergency vehicles and distributes notifications to affected non-emergency vehicles, achieving efficient coordination while keeping individual vehicle systems relatively simple.
Data Source
AI summary
Technologies for reporting and predicting emergency vehicle routes include a cloud server to receive emergency vehicle route data from an emergency vehicle, the emergency vehicle route data indicating a travel route of the emergency vehicle. The cloud server determines a scope of disclosure of the travel route to other vehicles based on the emergency vehicle route data and which other vehicles different from the emergency vehicle to which to convey the travel route of the emergency vehicle. The cloud server transmits a portion of the travel route of the emergency vehicle to the other vehicles based on the scope of disclosure.
