How Does Electrification Impact Road Freight Transport Efficiency? A System Dynamics Approach

Abstract

This paper explores the system-level impacts of electrification on road freight transport efficiency, as a complex concept with involvement of various stakeholders. Introducing electrification adds further complexity, bringing in new stakeholders, dynamics, and efficiencies. The paper utilises system dynamics modelling to understand the dynamics between different efficiencies and the impact of electrification. The results of the simulation model highlight that there are trade-offs between different kinds of efficiencies, and it is essential to achieve a balance. Moreover, worse-before-better behaviour should be expected, as electrification initially increases costs but has lower costs in the long term. The results point to two phases of E-truck adoption: during the first phase, the policy focus should be on expanding charging infrastructure; during the second phase, cost-focused policies become critical to boosting electrification. By understanding the impact of different policies, this paper offers valuable knowledge to decision-makers navigating the transition towards a more sustainable system.
