Congestion Costs - Congestion cost of road transport in Switzerland: Update for 2000 and 2005
Overview
Background & policy context:
In 1998 INFRAS on behalf of ASTRA, a study on the costs of congestion in road transport carried out (DIMAS 1998). There, the cost of traffic jams on the road were estimated at about 750 million to 1.2 billion CHF per year. The main part relates to time costs, the next relevant category, the accident cost and energy costs are lower than the time cost, and environmental costs are somewhat less important.
The congestion costs correspond to an amount of 0.2 to 0.4% of gross domestic product. Compared to foreign data where values are mentioned up to 2% of the GDP, these values were significantly lower.
Objectives:
The present study thematically deals with similar issues as its predecessor, albeit with changed objectives. In the present study, the following intentions are:
- As part of the update the external costs of road traffic for the year 2000 play an important - though specific - role and should therefore be quantified (including 2005).
- In the transport costs account for the year 2003 (SFS 2006d) congestion costs are not included. The present study closes this gap.
- The storage costs in passenger and freight traffic shall be lowered. The present study provides a basis for this.
- A key objective was to ensure continuity with the results from the previous study.
Methodology:
Because the main goal of this study is an update of the study carried out in 1998, it is methodologically similar as much as possible to ensure continuity.
