Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The automotive industry faces challenges in processing and analyzing high-volume vehicle location event data in real-time, particularly in identifying individual vehicle journeys and destinations, due to the vast amount of data generated, which conventional systems struggle to handle efficiently.
Innovation Solution
A system and method that ingest, validate, and encode location event data using geohashing to identify proximity, filter data with low latency, and anonymize it, enabling real-time analysis and processing of vehicle event data for up to 600,000 records per second, employing a processor configured to execute instructions for journey identification and active vehicle detection using connected components algorithms.

1Quantity of substance
If conventional systems process high-volume vehicle location event data, then data processing capacity is limited, but processing speed and real-time analysis capability deteriorate
Solution Approach 1:
The patent segments the high-volume data stream into manageable units by processing location events in batches or streams, using distributed computing architectures to divide the processing workload across multiple nodes. This allows the system to handle 200,000-600,000 records per second by distributing the computational burden rather than processing all data through a single conventional system.
Solution Approach 2:
The patent introduces intermediate data structures and processing layers (such as data lakes, message queues, and intermediate storage systems) that buffer and manage the high-volume incoming data stream. These intermediaries decouple the data ingestion rate from the processing rate, allowing the system to maintain high throughput while enabling real-time analysis capabilities through staged processing.
2Measurement precision
If individual vehicle data is analyzed in real-time, then journey identification accuracy improves, but data processing complexity increases
Solution Approach 1:
The patent applies preliminary filtering and preprocessing operations to location event data before full journey identification processing. By pre-validating data quality, pre-identifying potential journey boundaries, and pre-aggregating relevant features, the system reduces the complexity of subsequent real-time journey identification while maintaining high accuracy in distinguishing individual vehicle journeys.
Solution Approach 2:
The patent dynamically adjusts processing parameters such as journey detection thresholds, time window sizes, and data sampling rates based on traffic conditions, vehicle types, and analysis requirements. This allows the system to optimize between accuracy and complexity by adapting the processing intensity to the specific context of each data stream.
3Reliability
If data is anonymized for privacy protection, then data privacy is preserved, but data utility for individual vehicle analysis decreases
Solution Approach 1:
The patent applies different levels of anonymization to different portions of the data ecosystem. Individual vehicle data can be processed with minimal anonymization for real-time journey identification and operational analysis, while aggregated data for broader analytics applies stronger anonymization. This local differentiation preserves data utility where needed while protecting privacy where appropriate.
Solution Approach 2:
The patent implements a nested data structure where individual vehicle journey data is processed and analyzed in its original form for operational purposes, while simultaneously being aggregated into anonymized groups for statistical analysis and privacy-sensitive applications. This nested approach allows the same data to serve multiple purposes with different privacy requirements.
