This paper looks at the essential challenges and directions for a new value of time study for The Netherlands.
In The Netherlands, proposals for transport infrastructure projects are evaluated using a cost-benefit analysis (CBA). Time gains can be evaluated in CBA by using values of travel time saving (VTTS). For valuing travel time reliability gains, values of reliability (VoR) are available. For passenger and freight transport, the current values are based on national surveys carried out in 2010. The values are expected to change over time due to technological changes, changes in travel behavior, and socio-economic changes. Moreover, to cover benefits of transport policies better in CBA, new developed values, such as the concept of the value of comfort (VoC), come into focus. To have appropriate and up to date values, it is important to conduct empirical valuation studies on a regular basis. We prepare a new value of time study for The Netherlands. In this paper we point out the essential challenges and directions for this valuation study.
We will address the following challenges and issues in the paper:
• Benefits of transport modes such as autonomous vehicles, cycling and walking are not captured by the current VTTS
• Values of comfort as a concept to include the ongoing development of ICT and its potential to use travel time more productively and pleasantly
• Advantages and disadvantages of using the factor costs for determining the VTTS in freight transport instead of stated preferences
• The concept of buffer time as a travel time reliability presentation format for freight transport
• Non-linearity’s in the VTTS
• Transport forecasting models do not address reliability and comfort effects well
• Modeling tools do not address cycling and walking well
• A specifically designed national valuation study versus transferability of results of other European VTTS studies
• Collecting stated and/or revealed preference data
• Applicability of new methodological developments in data collection and modeling
