Is generalised cost justified in travel demand analysis?

Travel Cost Models of the Demand for Rock Climbing

In this paper we estimate the demand for rock climbing and calculate welfare measures for changing access to a number of climbs at a climbing area. In addition to the novel recreation application, we extend the travel cost methodology by combining the double hurdle count data model (DH) with a multinomial logit model of site-choice. The combined model allows us simultaneously to explain the dec...

Activity-based approach A modeling method that ac17 counts for the interdependent relationships among ac18 tivities and persons to derive travel demand equations. 19 Dynamic planning The incorporation of trends, cycles, 20 and feedback mechanisms into a process of actively 21 shaping our future. Desired futures are first defined in 22 terms of performance measures and a combination of 23 foreca...

Travel cost and time measurement in travel cost models TRAVEL COST AND TIME MEASUREMENT IN TRAVEL COST MODELS

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...

Passenger Travel Demand Forecasting

This paper addresses the importance of travel forecasting, the general direction of emerging forecasting methods, the importance of integrating land use and transportation forecasting, and this committee’s relationship to other committees at the Transportation Research Board (TRB). In particular, the movement from trip-based to activity-pattern or activity-scheduling methods of modeling is emph...
