Electric-road freight transport, Arlanda-Rosersberg logistic flow and environmental analysis.

University essay from KTH/Trafik och logistik; KTH/Trafik och logistik


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

area, reduce

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
