Autonomous Emergency Lane Creation for Priority Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for creating emergency lanes on high-speed roads are often confusing for drivers, leading to traffic jams as they struggle to clear a path for priority vehicles, such as ambulances, due to lack of awareness and confusion about the protocols, resulting in delayed response times for emergency services.
Innovation Solution
An autonomous emergency lane creation system using autonomous vehicle technology, which utilizes sensors, inter-car communication, and navigation systems to automatically generate and dissolve a rescue lane by modifying the steering and acceleration of surrounding vehicles to create a clear path for priority vehicles without requiring them to stop, while considering obstacles like pedestrians and cyclists.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If drivers manually create emergency lanes by steering away from priority vehicles, then a clear path can be formed for emergency services, but traffic congestion increases and response time is delayed due to driver confusion and incorrect execution
Solution Approach 1:
The system enables vehicles to automatically perform the lane creation task without human intervention. The autonomous vehicles detect priority vehicles and autonomously steer to form emergency lanes, eliminating the need for drivers to manually execute lane creation protocols.
Solution Approach 2:
The patent replaces the manual mechanical steering action by drivers with an automated control system using sensors, processors, and actuators. The system detects priority vehicles through sensors and automatically adjusts vehicle position and steering to create emergency lanes.
2Reliability
If drivers are required to stop and manually clear lanes for priority vehicles, then emergency access is enabled, but productivity of road traffic decreases significantly
Solution Approach 1:
The system dynamically adjusts vehicle positions and lane configurations in real-time based on the presence and movement of priority vehicles. Vehicles continuously modify their positions to maintain emergency lane clearance while preserving overall traffic flow, rather than static stopping and lane clearing.
Solution Approach 2:
The autonomous system proactively creates emergency lanes before priority vehicles arrive by detecting their approach and pre-positioning surrounding vehicles to clear the path, eliminating the need for reactive stopping and manual lane clearing.
3Reliability
If traditional emergency lane creation protocols are implemented, then emergency vehicles can access accident sites, but the complexity of driver coordination and communication increases
Solution Approach 1:
The system integrates multiple functions into a unified autonomous control platform that handles detection, decision-making, communication, and vehicle control. This multi-functional system replaces the need for separate driver actions, communication protocols, and coordination mechanisms.
Solution Approach 2:
The patent introduces an autonomous vehicle control system as an intermediary between priority vehicles and surrounding traffic. This intermediary automatically manages lane creation coordination, eliminating the need for direct driver-to-driver communication and coordination complexity.

AI summary
In one example, notice of a priority vehicle is obtained. A first protective field is generated around a current vehicle and a second protective field is generated around the priority vehicle. A priority lane is created by moving the first protective field of the current vehicle away from the second protective field of the priority vehicle.
