The research, released on arXiv (2608.16913v1), identifies Sydney's inner and western LGAs (CBD, Parramatta, Bankstown) as persistent high-risk zones, demonstrating the potential of IoT-based connected vehicle data for proactive road safety interventions.", "body_md": "arXiv:2608.16913v1 Announce Type: new\nAbstract: Road safety monitoring has historically been reactive, relying on crash-record analysis after fatalities and injuries have already occurred. Proactive identification of high-risk locations and dangerous driving behaviour before incidents occur is a critical but underexplored challenge. This paper addresses this gap using connected vehicle telemetry data from Greater Sydney, Australia, to detect and forecast near-miss risky driving events at the Local Government Area (LGA) level. Risky driving is quantified through g-force thresholds (hard braking >0.6g, harsh cornering >0.47g, harsh acceleration >0.5g), and spatio-temporal heatmaps are constructed to identify high-risk zones. Eight predictive models are benchmarked across three families: ensemble learning (Random Forests, XGBoost, LightGBM), deep learning (LSTM, N-BEATS), and classical time-series methods (ARIMA, Exponential Smoothing, Prophet). ARIMA achieves the lowest mean absolute error (MAE: 162.21), performing comparably to LSTM (MAE: 163.92) and outperforming all ensemble methods, with N-BEATS reaching an MAE of 180.75. These results demonstrate that parsimonious time-series models are competitive with deep learning approaches when training data volume is limited. The study highlights the potential of IoT-based connected vehicle data to support proactive road safety interventions, with Sydney's inner and western LGAs (CBD, Parramatta, Bankstown) identified as persistent high-risk zones warranting targeted policy action.", "url": "https://wpnews.pro/news/proactive-road-safety-intervention-in-australia-predicting-risky-driving-from", "canonical_source": "https://arxiv.org/abs/2608.16913", "published_at": "2026-08-19 04:00:00+00:00", "updated_at": "2026-08-19 04:13:15.322597+00:00", "lang": "en", "topics": ["machine-learning", "artificial-intelligence"], "entities": ["arXiv", "Greater Sydney", "ARIMA", "LSTM", "N-BEATS", "Random Forests", "XGBoost", "LightGBM"], "alternates": {"html": "https://wpnews.pro/news/proactive-road-safety-intervention-in-australia-predicting-risky-driving-from", "markdown": "https://wpnews.pro/news/proactive-road-safety-intervention-in-australia-predicting-risky-driving-from.md", "text": "https://wpnews.pro/news/proactive-road-safety-intervention-in-australia-predicting-risky-driving-from.txt", "jsonld": "https://wpnews.pro/news/proactive-road-safety-intervention-in-australia-predicting-risky-driving-from.jsonld"}}
