Travel Distance Judgment: An Environmental Distance Information Cognitive Processing Perspective

A consumer makes travel distance judgment to determine the place to visit. Stores that gain favorable travel distance judgment could gain access to a large volume of customer base. Travel distance judgment is often made with the aid of technologies, such as the mobile location-based service (LBS). In the present research-in-progress, we build on the human’s environmental distance information co...

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...

Value of Travel Time :Theoretical and Empirical Method

The value of travel time savings (VTTS) is the monetary value attached to save a determined amount of travel time. VTTS is also the most important benefit category aimed at justifying investments in transport infrastructures by public administrations. Hence VTTS played a significant role in various economic studies, both analytical and empirical (Zamparini & Reggiani, 2007). "It is difficult to...

Time, travel and infection.

The collapse of geographical space over the last 200 years has had profound effects on the circulation of human populations and on the transfer of infectious diseases. Three examples are used to illustrate the process: (a) the impact of the switch from sail to steamships in importing measles into Fiji over a 40-year period; (b) changes in measles epidemic behaviour in Iceland over a 150-year pe...
