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...

rapid urban growth is resulting into increase in travel demand and private vehicle ownership in urban areas. in the present scenario the existing infrastructure has failed to match the demand that leads to traffic congestion, vehicular pollution and accidents. with traffic congestion augmentation on the road, delay of commuters has increased and reliability of road network has decreased. four s...

in this paper the factors having influence on travel demand to iran are paper explored. the hypothesis of the research specifies the variable of “domestic upheavals and insecurity” as the most significant obstacle to expansion of the demand for travel to iran. to test the above hypothesis, first several demand models that have been proposed to study demand for tourism in different countries, ar...

This article argues that investigating the conceptual structure underlying the use of the pluperfect and the future perfect reveals a new complex type of nested dual mental time travel: mental time travel into posteriority embedded into mental time travel into “anteriority in the past” (underlying the pluperfect) versus mental time travel into posteriority embedded into mental time travel into ...

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...

Precise travel time prediction allows travelers and system controllers to be aware of the future conditions on roadways helps in pre-trip planning traffic control strategy formulation lessen mitigate congestion problems. This research investigates possibility using GPS trajectory dataset for Indian having heterogeneous disordered improvement accuracy by shifting from traditional historical aver...
