Summary
The Federal Ministry for Transport and Digital Infrastructures (BMVI) is currently preparing its medium- and long-term investment strategy in form of its new Bundesverkehrswegeplan 2015 (BVWP 2015). In this framework the project focussed on the estimation of values of time (VOT) and of reliability (VOR) and a proposal for recommended values for both private passenger travel and as well as business passenger travel. These recommended values will be used in the evaluation of the different investment proposals, which will form the BVWP.
In line with international practice the data collection adopted a two stage approach: in a first step the respondents reported about current trips (revealed preference (RP)), which were then systematically varied to be the basis for the experiments in the hypothetical choice situations (stated preference – SP). The study includes both experiments with a short-term horizon (route, mode, route and departure time), as well as long-term choice (work place and residential location). The well-known effect of longer distance or travel times on the time valuations were carefully studied with a series of different model formulations involving interaction terms and non-linear transformations of the variables.
The resulting VOTs and VORs can be differentiated by mode and trip purpose. The VOTs were also calculated for separate distances. Finally elasticities and ratios were determined. After careful testing, we could not find any small time savings effect in our data. The results of the VOT and VOR calculations are in line with recent international experiences.
