摘要

Environment and safety are two pillars of sustainable transport. Unlike existing studies that assess environmental impacts and safety concerns separately, in this paper we intend to capture the multifaceted nature of sustainable transport by combining environmental and safety factors. We formulate a unified performance measure using data envelopment analysis (DEA), a nonparametric method for benchmarking entities with multiple inputs and multiple outputs. In this method, environmental impacts (e.g., particulate matter and carbon dioxide emissions) and safety concerns (e.g., deaths and injuries in accidents) are treated as undesirable outputs under the slacks-based measure (SBM). We apply the model to conduct a joint assessment of environmental impacts and safety concerns of road transport for a group of OECD countries over the period 2000-2014. We show that the unified measure from joint assessment can be drastically different from that of assessing environment and safety separately. Furthermore, we investigate the relationship between the assessment results and socio-economic factors, and find that disposable income, governance quality and urbanization are significantly associated with the level of transport sustainability.
