Electric-road freight transport, Arlanda-Rosersberg logistic flow and environmental analysis.
The expected economic and social growth, joint with the increase on the demand of services
and goods that this will cause, will become an environmental problem (emissions and noise) as
well as a logistical problem (congestion) that needs to be solved. The transport sector has to
reduce drastically the use of fossil fuels and Sweden’s goal is to achieve a fossil independent
vehicle fleet by 2030. It is expected that 2/3 of the traffic volume of trucks in Sweden will be
performed along electrified roads. The most efficient way to achieve this is to use electricity
and now that the technology to power trucks without the need of huge batteries has been tested
and approved, is time to develop the infrastructure needed and study its impact in
transportation and logistics.
An electric road is planned to be operative around 2020 from Rosersberg logistics hub to
Arlanda airport cargo city. The objective is to transfer goods from the logistic area to the
freight terminal by the use of electric trucks. It will optimize the transit of logistics flow in the
emissions and release the traffic pressures on E4 at the same time.
Arlanda airport used to have a restriction on the emission rate of all the companies operating
inside Arlanda, the emissions of the trucks that drive the cargo outside Arlanda was also taken
into account. This means that in order to be below the maximum levels, the high ground
transport emissions limited the number of planes that could fly. Affecting therefore the
capacity of handling bigger volumes and passengers. So in order to prevent this situation from
happening again in the future (more environmental restrictions will appear) the best solution
for all the parts involved is to give priority to sustainability in transport planning.
The aim of this project is to come up with conclusions and forecasts of the whole
transportation network according to the logistics needs, by analysing the economic,
environmental and logistic impacts of using the El-road. The result expected is to provide a
clearer overall picture of the logistic flows between Rosersberg, Arlanda Airport, Gavle
container and nearby locations, such as Stockholm or Uppsala. As well as analyse the possible
scenarios that might develop once the El-road is operating.
Due to the nature of our data we decided to use qualitative and subjective methods rather than
quantitative ones. AHP (Analytic Hierarchy Process, Saaty 1970), will enable us to derive ratio
scales from paired comparisons by defining the different criteria (cost, time, operations and
sustainability) and assigning values to their respective sub criteria. These values will be
assigned by each of the companies working inside Arlanda, since the goal is to define the best
possible scenario for them in the future.
The other method we will use is the decision tree analysis, this model of decisions and possible
consequences that can occur will show a graph of all the variables that must be taken into
account while defining the issues that will lead to one scenario or another. We consider it the
best method to analyse and show how many facts can affect the final scenario outcome of this
