Abstract
More than 50% major road accidents are caused by risk driving behaviors from professional drivers of Heavy Duty Vehicles (HDVs). The quantitative estimation of driving performance and driving behaviors portrait for professional drivers is helpful to measure the driver's driving risk and inherent driving style. Previous studies have attempted to evaluate risk driving behavior, but most of them rely on high-demand vehicle and driving data. However, few studies can dig into the causes and correlations behind individual driving behavior and quantify the driving behaviors portrait for professional driver based on long-term naturalistic driving. In this study, the data is from On-Board Unit (OBU) devices mounted in the HDVs in China. Based on the driving behavior pattern diagram and the frequency and ranking of drivers' typical driving patterns, a driving behavior portrait approach is proposed by comprehensively considering the vehicle safety, driving comfort, and fuel economy indicators. The similarities and differences of different drivers' driving behaviors are quantitatively analyzed. The high precision and sampling frequency data from vehicles are used to verify the proposed approach. The results demonstrated that the driving behavior portrait approach can digitally describe the individual driving behaviors styles and identify the potential driving behaviors with long-term naturalistic driving data. The development of this approach can help quantitatively evaluate the individual characteristic of risk driving behaviors to prevent road accidents.

Summary
More than 50% major road accidents are caused by risk driving behaviors from professional drivers of HDVs [1]. Based on the driving behavior pattern diagram and the frequency and ranking of drivers’ typical driving patterns, a driving behavior portrait approach is proposed by comprehensive considering the vehicle safety, driving comfort, and fuel economy indicators, to quantitatively evaluate the personalized driving behavior of different drivers and identify potential risk driving behaviors, so as to improve the assessment accuracy of the risk model and reduce the accident risk. E frequency and size of overspeed event, aggressive acceleration event, and aggressive braking event were used as the behavior measurement indexes, and their spatial and temporal characteristics were used as the influencing factors Based on these parameters, the behavioral characteristics of drivers were established and the total score representing driving risk was given [5]. This paper proposes an individual driving behavior portrait by comprehensively considering the vehicle safety, driving comfort, and fuel economy indicators to quantify the potential risk driving behaviors and driving styles
