Värdering av minskad transporttid och minskad variation i transporttid för godstransporter: förstudie

Download

This pre-study on behalf of the Swedish Road and Rail Administrations addresses the values for time savings and improved reliability in freight transport in the cost benefit analyses (CBA). - Values of transport time savings (VTTS)' are assumed to be related to a) shorter use of transport resources, b) less unproductive use of goods in transport, c) lower opportunity costs for example for standstill of production. "Value of transport time variability (VTTV) relates to a) reduction of transport resources required to ensure a given service level and b) reduced stocks or opportunity costs. Sweden appears to be the only country which uses VTTS to denote only the benefits related to goods. The analysis of actual Swedish investment calculations shows that industry's benefits related to VTTS and VTTV are not fairly treated. Recommendations to Swedish decision makers are: - to clarify the general structure of CBA in which estimates of VTTS and VTTV are used, - to use existing mechanisms in the Swedish logistics model to calculate transport demand and costs for the transport resources and to develop the missing mechanisms separately, - to perform Revealed Preference-studies, i.e. to analyse the possibilities to use data from the Swedish Commodity Flow Survey, - to carry out a thorough assessment of the coming Dutch Stated Preference-study, - to develop methods to valuate reliability, - to improve the knowledge about the components related to opportunity costs.
