This study introduces a novel method for real-time abnormal traffic detection on freeways using vehicle telematics data. The system provides lane-level warnings, improving safety and reducing delays compared to traditional methods.

Area of Science:

Intelligent Transportation Systems
Traffic Engineering
Data Science

Background:

Traditional abnormal traffic detection methods suffer from delays and lack precise location data.
These limitations pose safety risks and lead to economic losses in intelligent transportation systems.

Purpose of the Study:

To develop a real-time, lane-level abnormal traffic detection system for freeways.
To utilize sparse telematics trajectory data for efficient and low-cost traffic monitoring.

Main Methods:

Offline stage: Discretizing historical trajectories into spatial cells, estimating vehicle intention, and setting alert thresholds using crash reports.
Online stage: Mapping real-time data to cells, scoring for transition anomalies, speed deviations, and lateral risks.
Accumulating cell-specific risks to generate a risk map and issue warnings when thresholds are exceeded.

Keywords:

Main Results:

Achieved a 75% identification rate with lane-level localization and 96% overall accuracy.
Obtained an F1-score of 0.84 with a low false alarm rate of 0.6% for non-crash events.
Detected 13% of crashes more than 3 minutes before official notification times.

Conclusions:

The proposed telematics-based system offers a real-time, low-cost solution for lane-level abnormal traffic detection.
This approach significantly enhances traffic safety and efficiency in intelligent transportation systems.
Early detection capabilities can mitigate risks and economic impacts associated with traffic incidents.
