Abstract

Truck-involved crashes represent a persistent challenge to global road safety, with drivers' aberrant driving behaviors (ADBs) identified as a primary contributing factor. To address the limitations of the Theory of Planned Behavior (TPB) in capturing the complexity of high-constraint occupational settings, this study develops an integrated TPB–Social Cognitive Theory (SCT) framework to examine the mechanisms underlying ADBs. The model incorporates regulatory cognition (legal literacy), behavioral capability (driving skill), and risk perception, alongside key contextual influences, including occupational characteristics (driving intensity, safety policy) and environmental conditions (road monotony, facilitating circumstances, and adverse weather). Using survey data from 392 professional truck drivers and Structural Equation Modeling, the results reveal a differentiated mechanism structure. Legal literacy emerges as the dominant determinant of behavioral intention, exerting the strongest total effect through both direct and indirect pathways by shaping attitudes and subjective norms. Notably, subjective norm and facilitating circumstances also significantly influence intention, whereas the direct effects of attitude and perceived behavioral control are not significant, indicating a context-dependent restructuring of TPB mechanisms under high external constraints. In addition, risk perception and driving skill contribute indirectly through cognitive and capability pathways, further reinforcing the system-level nature of ADB formation. Theoretically, this study extends the TPB by integrating SCT-informed constructs and identifying dual pathways—cognition-driven and capability-driven mechanisms—underlying ADBs. Practically, it advances a mechanism-informed intervention framework that targets regulatory knowledge, social norms, driver competence, and operational environments in an integrated manner, thereby providing actionable guidance for systemic safety management in road freight transport.

货车司机异常驾驶行为形成机制的建模：一个集成的TPB-SCT框架

卡车事故对全球道路安全构成了持续的挑战，驾驶员的异常驾驶行为（ADBs）被认为是主要的影响因素。为了解决计划行为理论（TPB）在捕捉高约束职业环境复杂性方面的局限性，本研究开发了一个综合的TPB -社会认知理论（SCT）框架来研究ADBs的潜在机制。该模型结合了监管认知（法律素养）、行为能力（驾驶技能）和风险感知，以及关键的背景影响，包括职业特征（驾驶强度、安全政策）和环境条件（道路单调、便利环境和恶劣天气）。通过对392名专业卡车司机的调查数据和结构方程建模，揭示了差异化的机制结构。法律素养作为行为意向的主要决定因素，通过塑造态度和主观规范的直接和间接途径发挥最大的总效应。值得注意的是，主观规范和便利环境也显著影响意愿，而态度和感知行为控制的直接影响不显著，这表明在高外部约束下，TPB机制的重构依赖于情境。此外，风险感知和驾驶技能通过认知和能力途径间接促成，进一步强化了ADB形成的系统级性质。从理论上讲，本研究通过整合sct信息结构和识别ADBs背后的双重途径——认知驱动和能力驱动机制，扩展了TPB。实际上，它提出了一个机制知情的干预框架，以综合的方式针对监管知识、社会规范、驾驶员能力和操作环境，从而为道路货运的系统安全管理提供可操作的指导。

期刊介绍： Transportation Research Part F: Traffic Psychology and Behaviour focuses on the behavioural and psychological aspects of traffic and transport. The aim of the journal is to enhance theory development, improve the quality of empirical studies and to stimulate the application of research findings in practice. TRF provides a focus and a means of communication for the considerable amount of research activities that are now being carried out in this field. The journal provides a forum for transportation researchers, psychologists, ergonomists, engineers and policy-makers with an interest in traffic and transport psychology.
