N2 - Minor incidents such as signal failure, vehicle breakdown, etc. are common in our day-to-day travel. These incidents cause random link capacity degradations, leading to travel time uncertainty. Over time, commuters acquire the routes' travel time variability and factor them into their route choice decisions. To hedge against this uncertainty, travelers typically add a travel time margin to the expected travel time of a trip to form the "travel time budget" Nevertheless, in this learning process, commuters may have perception variations in the traffic conditions they actually encounter. In summary, travelers face two types of uncertainty in their daily commutes. In this study, we formulated a stochastic equilibrium formulation to address both types of uncertainty. Using this stochastic formulation as a platform, through a set of numerical studies, we studied the effects of network links strengthening and traffic information provision.
