In applying monetary evaluation methods of infrastructural projects and other policy measures in transportation, travel time gains and losses are converted into money units, using value-of-time information. For establishing value-of-time measures in freight transport, several methods can be used. One of those is Stated Preference (SP) analysis. This paper contains a description of the method used and the results obtained in a research project into the value-of-time in goods transport by road, rail and inland waterways in The Netherlands. A computer based SP experiment is designed to capture the carriers' and/or shippers' trade-off between travel time, travel cost, reliability, frequency and probability of damage. The specific questions a carrier or shipper has to answer and the values of the attributes of a 'typical transport' for some mode are made dependent on the answers previously given. This way the SP is made a 'Contextual Stated Preference' (CSP). The above 'within-mode' CSP experiment is thought to render short term value-of-time measures. A further 'strategic' SP experiment into the trade-off between overall (all modes, all transport) travel time gains and increased taxation has been piloted to yield indications of the long-term value-of-time.
