Autonomous Vehicle Queue Detection for Pickup and Drop-Off Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous vehicles lack the intuition to recognize and respond to queuing behaviors, often causing inconvenience and traffic congestion by improperly joining or exiting queues, which can lead to unsafe conditions for other road users.
Innovation Solution
The vehicle's computing devices use sensor data and machine learning models to determine if a queue exists, decide whether to join it, and navigate to a designated spot for pickup or drop-off, reducing the need for remote operator intervention by assessing traffic patterns and queuing behaviors independently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If autonomous vehicles join queues at pickup and drop-off locations, then service capability is improved, but traffic congestion and inconvenience to other road users worsen
Solution Approach 1:
The system performs preliminary analysis of queue conditions using sensor data before the autonomous vehicle joins the queue. The computing device determines whether a queue exists and evaluates traffic patterns in advance, allowing the vehicle to make informed decisions about queue joining that balance service capability with minimal disruption to traffic flow.
2Measurement precision
If autonomous vehicles use sensor data and machine learning to determine queue existence, then decision accuracy is improved, but system complexity worsens
Solution Approach 1:
The autonomous vehicle's computing device independently analyzes sensor data using machine learning models to determine queue existence and make queue joining decisions. The system serves itself by autonomously processing perception data and generating control decisions without requiring external intervention, thereby achieving high decision accuracy while managing complexity through self-contained processing.
3Extent of automation
If autonomous vehicles independently assess traffic patterns, then operational autonomy is improved, but need for remote operator intervention worsens
Solution Approach 1:
The system continuously receives sensor data from the perception system and uses this feedback to dynamically adjust queue joining decisions. The machine learning model processes ongoing traffic pattern information, allowing the autonomous vehicle to maintain high operational autonomy while having the capability to request remote operator intervention only when necessary, thereby reducing information loss.

AI summary
Aspects of the disclosure provide for controlling an autonomous vehicle to respond to queuing behaviors at pickup or drop-off locations. As an example, a request to pick up or drop off a passenger at a location may be received. The location may be determined to likely have a queue for picking up and dropping off passengers. Based on sensor data received from a perception system, whether a queue exists at the location may be determined. Once it is determined that a queue exists, it may be determined whether to join the queue to avoid inconveniencing other road users. Based on the determination to join the queue, the vehicle may be controlled to join the queue.
