| Abstract: | In this work, laboratory experiment was conducted in order to evaluate the effect of feedback on decision-making under uncertainty,
with and without provided information about travel times. We discuss the prediction of travelers’ response to uncertainty
in two route–choice situations. In the first situation travelers are faced with a route–choice problem in which travel times
are uncertain but some external information about routes’ travel times is provided. The second situation takes place in a
more uncertain environment in which external information about travel times is not provided, and the travelers’ only source
of information is their own experience. Experimental results are in conflict with the paradigm about traveler information
systems: As a consequence of information, the propensity of travelers to minimize expected travel time is not necessarily
increased. Providing travelers with static information about expected travel times reveals an increase in the heterogeneity
of travelers’ choices and reduces the maximization rate. |
