Route choice decision under uncertainty

چکیده
We study route choice behavior when travel time is uncertain. In this case, users do not minimize expected travel time but also take into account travel time variability. We collected survey data and analyze them with a method based on the ordered probit model. This allows us to have an ordinal as well as cardinal measures of risk aversion. Such an approach is therefore consistent with expected as well as with non-expected utility theory. Survey data suggest a series of key factors which explain the degree of risk aversion.

The Impact of Travel Time Information on Travellers' Learning under Uncertainty
In this work, route-choice simulations and laboratory experiments were conducted in order to evaluate the effect of feedback mechanism on decision-making under uncertainty, with and without provided information about travel times. We discuss the prediction of travellers' response to uncertainty in two route-choice situations. In the first situation travellers are faced with a route-choice probl...
متن کاملRational Choice Theory: A Cultural Reconsideration
Economists have heralded the formulation of the expected utility theorem as a universal method of choice under uncertainty. In their seminal paper, Stigler and Becker (Stigler & Becker, 1977) declared that “human behavior can be explained by a generalized calculus of utility-maximizing behavior” (p.76). The universality of the rational choice theory has been widely criticized by psychologists, ...
متن کاملHedonic Pricing under Uncertainty: A Theoretical Consumer Behavior Model
A model of consumer behavior has been formulated by using an additive utility function and the hedonic pricing approach, in a virtual market. Since, there is a time lag between ordering and purchasing products (goods and services) online and receiving them, it means the consumer makes decision under uncertainty. The level of satisfaction with products with distinctive characteristics is describ...
متن کاملPedestrian route-choice and activity scheduling theory and models
Among the most interesting and challenging theoretical and practical problems in describing pedestrians behavior are route choice and activity scheduling. Compared to other modes of transport, a characteristic feature of pedestrian route choice is that routes are continuous trajectories in time and space: since a pedestrian chooses a route from an infinite set of alternatives, dedicated theorie...
