Solution Overview

Problem

Existing traffic prediction methods lack accuracy in long-term predictions and fail to effectively incorporate contextual factors, leading to inefficient route planning and management in vehicular traffic systems.

Innovation Solution

A computer-implemented method using a trained neural network to model the relationship between historical traffic data and contextual data for roadway links, allowing for accurate prediction of future traffic conditions by considering factors like weather, events, and road conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If traditional traffic prediction methods are used, then the system is simple to implement, but prediction accuracy deteriorates over long-term periods

Engineering Contradiction:
Improveprediction accuracyVSAvoidprediction time horizon
Core Design Contradiction:
Measurement precisionVSDuration of action of stationary object

Solution Approach 1:

The system performs preliminary actions by collecting and storing contextual data (weather forecasts, event schedules, road work information) in advance before prediction is needed. This allows the neural network to have access to future contextual information when making long-term predictions, thereby maintaining high accuracy over extended time horizons without increasing system complexity

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The neural network acts as an intermediary that processes and integrates multiple data sources (historical traffic data, contextual data, weather information, event data) to produce accurate long-term predictions. This intermediary processing layer enables the system to maintain prediction accuracy by synthesizing complex relationships between various factors over time

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If contextual factors are not incorporated, then the prediction model is simpler, but route planning efficiency deteriorates

Engineering Contradiction:
Improveroute planning efficiencyVSAvoidmodel complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The neural network model is designed with multi-functionality to handle diverse data types (traffic flow, weather, events, road conditions) within a single unified framework. This universal approach allows the system to incorporate multiple contextual factors without proportionally increasing complexity, as the same network architecture processes all data types, thereby maintaining route planning efficiency

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system dynamically adjusts model parameters based on the availability and relevance of different contextual factors. By changing parameters such as data weighting, time horizons, and feature importance, the model can adapt to varying conditions without requiring complete redesign, thus maintaining efficiency while incorporating rich contextual information

Inventive Principle:
Principle #35Parameter changes

AI summary

This disclosure provides embodiments for context based vehicular traffic prediction. A trained neural network modeling a relationship between historical traffic data and associated historical contextual data for a roadway link is obtained. Expected contextual data for a future time period for the roadway link is acquired. Predicted traffic data for the future time period for the roadway link is generated with the trained neural network based on the expected contextual data.
