have used either revealed preference or stated preference data and various forms of logit choice models (e.g., multinomial, nested, and mixed random effect) to identify marginal rates of substitution between travel time and the price of a trip. It is intuitive that the value of travel time is not constant in all situations. Previous studies suggest it varies by assorted trip characteristics inc...

In this paper we use the results of a recent on-site recreation survey to know whether it matters to use perceived rather than calculated travel costs. The calculated travel costs (time and money) are derived from detailed GIS computations. The perceived travel times and costs are taken directly from the survey responses. We first find that there is a high non-response rate for the perceived co...

The value of time (VOT) is one of the most important values in transportation planning. Although the trip-based models are widely used for estimating the VOT, the trip-based travel model can evaluate the VOT for travelers only. This paper formulates the individual’s choice of whether to travel or not with an activity-based modeling approach. I develop a discrete choice model and a discrete-cont...

The paper tests ‘twoalternative specifications for the opportunity cost of time in travel cost models. The standard travel cost survey design is enriched to include a contingent valuation type question about peoples’ willingness to accept compensation to forgo a precisely defined recreational experience. It is hypothesized that individually revealed value of time more appropriately reflects the...
