System-level Impact Study of Transportation on Electrified Roads in Sweden

Important results from the project

SISTERS aimed to develop three key components for system-level design of electrical road systems (ERS) for Swedish circumstances. By extending existing ERS life cycle assessment frameworks for the Swedish circumstances, the project helps to look at the total CO2 balance of ERS for Sweden. With simulation and laboratory tests, the potential structural issues of ERS solutions will be tested for general roads. A participatory approach will be developed to be able to involve societal stakeholders in planning of the technology on real roads.

Expected long term effects

The project resulted in adaptations to the FABRIC LCA systems for ERS, which have been made available to other stakeholder in the Swedish ERS community. The simulations and laboratory experiments of embedding ERS technology i roads leads to the conclusion that binders between foreign objects and the asphalt pavement are critical, but that careful selection with currently available binder technology can overcome most issues. The participatory approach based on data mining has been particularly useful for potential service development with fleet management data.

Approach and implementation

The project has been carried out by two departments at KTH, one specialised in road constructions and one in participatory models and data mining. The first group has efficiently extended the work in the EU FABRIC project with LCA, simulation and laboratory tests for Swedish circumstances. The second group has worked closely with Scania, and has interned one researcher there under a 2 year period for 1 - 2 days per week. Experiments with the participatory planning framework have been organised via own contacts with Swedish projects (Arlanda and E16).
