Bengt Olsson explains that the method used to calculate the social benefit of infrastructure projects provides a sufficient basis to make decisions and therefore, have not changed.
– Sverigeförhandlingen pulled out at the time and we would deliver quickly and had no time to translate the models, the KTH-group had developed to be adapted to Swedish conditions. Then, we chose the tried and tested method.
– Yes, from the transportekonomiskt institutions, which is one of those who approved and adopted the method we use today.
" We are open to looking at other methods, but then it's down to what is good enough to be able to make this type of decision. Just when it was done we had the demands on us to deliver in time.
" There are certainly different opinions on what is best. But there we were forced to put down the foot and use the models that we had already used.
" I absolutely believe that you can look at the KTH model and what possible future can stop in. It is something we are open to and want to have a further discussion.
