Analysis of effects and consequences of constructing Inductive Power Transfer Systems in road infrastructure. : A case study for the Stockholm region (Sweden).
The continuous growth in road transportation demand requires the development towards
sustainable strategies. The concept of Smart Roads is arising as a convergence of technologies
that will lead the mobility by road into a more efficient and interactive system between
infrastructure, environment and vehicles. Within this context, e-mobility appears as one of the
The implementation of e-mobility based on Electric Vehicles (EVs) has been restricted by
numerous shortcomings such as their driving range, the battery size, the dependence on
charging stations and the time required for its charging. However, the electrification of the
road infrastructure, which will enable a dynamic charging of the EVs while driving, is
becoming a potential solution to overcome these deficiencies.
This study aims to contribute for the future introduction of electrified roads (eRoads) into the
current network, by focusing on the effects and consequences of embedding Inductive Power
Transfer (IPT) systems in the road infrastructure. A structural design of an eRoad is
conducted through a Finite Elements Analysis (FEA) by analysing the behaviour of a
pavement structure based on Swedish conditions subjected to traffic loading. Valuable
conclusions can be displayed from this analysis and thus, a summary concerning
considerations and effects over the design, construction and maintenance of eRoads can be
built. Nevertheless, this analysis must be complemented and coordinated from a lifetime
perspective to reach the social, environmental and economic requirements related to the
development of road infrastructure nowadays. Hence, a guideline from a life cycle approach is
stated over the integration of eRoads in order to enable the assessment of the infrastructure
during its different phases.
To be sustainable, the development of road infrastructure must reach not just structural and
appropriate performance requirements, but also preserve the environmental and economic
impact. This thesis pretends to combine all these aspects as a state of the art, providing a basis
that stands out the most relevant issues related to the feasible implementation of eRoads in the mid-long term.
