Lane Change Recommendation at Intersections With Turning Vehicle Blockage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to provide an effective lane change recommendation for vehicles at traffic network nodes, particularly when obstacles such as pedestrians or bicyclists are present, leading to inefficient lane selection and increased delay times.
Innovation Solution
A device and method that utilizes a processing unit to analyze image data, navigation data, and communication systems to determine the presence of obstacles and the intention of preceding vehicles, and calculates a lane change recommendation based on delay times and lane availability, ensuring time-efficient navigation through traffic network nodes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the vehicle stays on the first lane to maintain current trajectory, then the navigation path is simple, but the delay time increases due to preceding vehicles turning off blocking the lane
Solution Approach 1:
The system performs preliminary analysis of the traffic situation at the intersection, identifying preceding vehicles that are turning off and will block the lane. Based on this advance information, the system recommends lane changes before the vehicle reaches the blocking point, allowing the vehicle to avoid delays without complex real-time decision-making at the intersection itself.
Solution Approach 2:
The system introduces an intermediary processing unit that analyzes image data, navigation data, and communication data to determine the intentions of preceding vehicles. This intermediary system translates complex traffic patterns into simple lane change recommendations, reducing the operational complexity for the driver while optimizing travel time.
2Loss of time
If the vehicle changes lane to avoid blocking by preceding vehicles, then the delay time is reduced, but the risk of collision with obstacles increases
Solution Approach 1:
The system continuously monitors the traffic environment using image recording units and communication systems, providing real-time feedback about obstacles and traffic conditions. This feedback loop allows the system to dynamically adjust lane change recommendations, confirming safety before recommending a lane change and updating recommendations as conditions change, thereby reducing collision risk while maintaining time efficiency.
3Productivity
If the system provides detailed lane change recommendations based on comprehensive analysis, then the travel time is optimized, but the system complexity increases
Solution Approach 1:
The processing unit is designed to handle multiple functions: analyzing image data from recording units, processing navigation data, receiving communication data from other vehicles or infrastructure, determining traffic situations, and generating lane change recommendations. This multi-functional design consolidates complexity into a single versatile system rather than requiring separate specialized systems for each function.

AI summary
A device and a method for determining a lane change recommendation for a vehicle are provided. A processing unit determines a lane change recommendation from a first lane to a second lane if the processing unit has determined that the length of a preceding vehicle turning from the first lane into a third lane is longer than the relevant distance between a crossing area and the first lane running in the first direction via a traffic network node.
