Purpose

This research examines what motivates professional truck drivers to engage in eco-driving by linking their self-reports with objective driving scores.

Design/methodology/approach

Theory of Planned Behavior (TPB) is illustrated in an embedded, single-case study of a Finnish carrier with 17 of its truck drivers. Data are obtained through in-depth interviews with drivers, their fuel-efficiency scores generated by fleet telematics and a focus group session with the management.

Findings

Discrepancies between drivers’ intentions and eco-driving behaviors are illustrated in a two-by-two matrix that classifies drivers into four categories: ideal eco-drivers, wildcards, wannabes and non-eco-drivers. Attitudes, subjective norms and perceived behavioral control are examined for drivers within each category, revealing that drivers’ perceptions did not always align with the reality of their driving.

Research limitations/implications

This study strengthens the utility of TPB through data triangulation while also revealing the theory’s inherent limitations in elucidating the underlying causes of its three antecedents and their impact on the variance in driving behaviors.

Practical implications

Managerial insights are offered to fleet managers and eco-driving solution providers to stipulate the right conditions for drivers to enhance fuel-efficiency outcomes of transport fleets.

Originality/value

This is one of the first studies to give a voice to professional truck drivers about their daily eco-driving practice.

推动谈话：研究专业卡车司机参与生态驾驶的动机

目的

本研究通过将他们的自我报告与客观驾驶分数联系起来，检验是什么促使专业卡车司机参与环保驾驶。

设计/方法/途径

计划行为理论 (TPB) 在芬兰承运商及其 17 名卡车司机的嵌入式单一案例研究中得到了说明。数据是通过与司机的深入访谈、车队远程信息处理生成的燃油效率分数以及与管理层的焦点小组会议获得的。

发现

司机的意图和环保驾驶行为之间的差异在一个二乘二的矩阵中得到了说明，该矩阵将司机分为四类：理想的环保司机、通配符、崇拜者和非环保司机。对每个类别中的驾驶员的态度、主观规范和感知行为控制进行了检查，揭示了驾驶员的感知并不总是与他们的驾驶现实保持一致。

研究局限性/影响

本研究通过数据三角测量加强了 TPB 的实用性，同时也揭示了该理论在阐明其三个前因的根本原因及其对驾驶行为差异的影响方面的内在局限性。

实际影响

向车队经理和生态驾驶解决方案提供商提供管理见解，为司机规定合适的条件，以提高运输车队的燃油效率。

原创性/价值

这是首批让专业卡车司机了解他们日常生态驾驶实践的研究之一。
