Travel outcome and performance: The effect of uncertainty on accessibility
AbstractAn accessibility model is a conceptual tool which explains the interdependencies between the transportation infrastructure and human activities. Traditionally, theorists have based their accessibility models upon deterministic approximations. However, uncertainty in itself can affect whether an activity is accessible, and affect how one measures accessibility. In the first section of this paper, it is shown that travel time randomness interacts with the scheduling of human activities to define the region which is accessible to a traveler. In the second section, a problem is considered where a traveler must search among opportunities to locate a certain activity he desires. It is found that there exists an optimal cluster size which minimizes travel cost, the size being a decreasing function of the probability of locating the activity at any single opportunity.
