# Summary

### 1 Introduction

It should be noted that even the calculation "to the name" applies to a specific stretch, all cost estimates and calculations are done on a flat-rate basis. The calculation is therefore valid in principle for any stretch with the same volume of heavy traffic.

### 2 Starting points for the calculation

The minimum value for heavy traffic (ÅTD) on the Södertälje-Helsingborg route is 2600. In the socioeconomic calculation, this value is used as an estimate of through traffic. No traffic estimation is performed, but the flow is assumed to be constant over the calculation period.

Thus, approximately 530 million heavy vehicle kilometers are driven annually between Södertälje and Helsingborg.

The calculation assumes that a share of traffic is transferred from diesel to electric power. How much this share would be if the distance was really provided with the necessary infrastructure obviously depends on business-related aspects, which have not been investigated here. The basic assumption is that 10 percent of the heavy traffic is transferred to electric power (hybrid vehicles). 53 million vehicle kilometers would then be transferred to electrical operation. Provided that the choice between electric and diesel operation is voluntary and without regulation, the proportion will be
Traffic that is really passed over to be determined by business-related aspects, which are not investigated here.

We assume that an average vehicle for long-haul transport rolls 600 km per day (219 000 km / year). There would then be needed about 240 electrified long haulers to perform the estimated traffic work.
