Abstract

This paper presents the results of a ranking-type Delphi study on the critical risk factors for the adoption of an electric road system (e-road) for trucks on the main motorways in Sweden. The investment cost of such a system is high, necessitating an upfront evaluation of the adoption risk factors to reduce the likelihood of budget overruns and project delays. Participating Swedish e-road experts (N = 52) from the public sector, private sector, and academia identified 32 unique risk factors, which were divided into five categories. The three most critical risk factors, as ranked by the experts, were ‘low expansion rate,’ ‘low utilization rate,’ and ‘lengthy public-sector evaluation.’ Overall, market and financial risks were ranked as more important than institutional, technological, and sustainability risks. This study has important implications for policymakers in countries considering e-road adoption.
