Solution Overview

Problem

Current navigation systems do not provide optimal lane selection recommendations for vehicles to reach a destination efficiently, as they lack real-time traffic condition assessments and feedback mechanisms to improve lane choice decisions.

Innovation Solution

A system utilizing machine learning models, combined with camera imagery and sensor data, to assess traffic conditions and provide lane recommendations by determining vehicle speeds in each lane, using contextual bandit techniques to delay feedback until the end of a route or waypoint, thereby optimizing lane changes based on cumulative travel time and discomfort metrics.

1Productivity

If step-by-step driving instructions are provided without lane-specific recommendations, then the navigation system remains simple and easy to operate, but the vehicle cannot reach the destination in an optimal manner

Engineering Contradiction:
Improvenavigation efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system implements feedback by collecting actual travel times from vehicles that followed lane recommendations and using this data to continuously improve the machine learning model. The feedback loop compares predicted travel times with actual outcomes, enabling the system to learn and optimize lane selection strategies over time, thereby improving navigation efficiency without requiring complex manual intervention.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The navigation system performs self-service by automatically assessing traffic conditions, generating lane recommendations, and evaluating their effectiveness without requiring driver input or manual adjustments. The machine learning model autonomously processes sensor data, determines optimal lanes, and learns from accumulated travel time data, enabling the system to self-optimize navigation routes while maintaining simplicity for the user.

Inventive Principle:
Principle #25Self-service

2Productivity

If real-time traffic assessment and machine learning models are implemented to provide optimal lane recommendations, then navigation efficiency is improved, but the system complexity and computational requirements increase

Engineering Contradiction:

Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system autonomously performs traffic assessment, lane recommendation generation, and performance evaluation without requiring external intervention. The machine learning model automatically processes sensor data, applies contextual bandit algorithms, and learns from accumulated feedback, enabling the system to self-optimize lane selection while maintaining operational simplicity for users.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system implements contextual bandit techniques that delay feedback collection until the end of a route or waypoint rather than requiring continuous real-time assessment. This partial feedback approach reduces computational complexity by processing information at strategic intervals while still achieving effective lane selection optimization through cumulative learning.

Inventive Principle:
Principle #16Partial or excessive action

3Reliability

If feedback is collected continuously during lane selection, then the machine learning model can improve rapidly, but the system requires complex real-time data processing and storage infrastructure

Engineering Contradiction:
Improvemodel accuracyVSAvoiddata processing complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system implements delayed feedback collection by waiting until the end of a route or waypoint to gather travel time data, rather than continuously monitoring and processing feedback in real-time. This approach reduces data processing complexity by consolidating feedback collection events while still providing sufficient data for the machine learning model to improve accuracy through cumulative learning experiences.

Inventive Principle:
Principle #16Partial or excessive action

Solution Approach 2:

Feedback collection occurs periodically at strategic intervals (completion of routes or waypoints) rather than continuously. This periodic feedback mechanism reduces the computational burden of real-time data processing while maintaining model reliability through regular updates based on accumulated travel time data from actual lane selection outcomes.

Inventive Principle:
Principle #19Periodic action

AI summary

To selecting a lane in a multi-lane road segment for a vehicle travelling on the road segment, a system determines current traffic information for the road segment including a plurality of lanes and applies the current traffic information to a machine learning (ML) model to generate an indication of one of the plurality of lanes in which the vehicle is to travel. Subsequently to the vehicle selecting the indicated lane, the system determines an amount of time the vehicle took to travel a certain distance following the selection, and provides the determined amount of time to the ML model as a feedback signal.
