Risk-Averse Transit Equilibrium Assignment

The classic transit assignment model assumes that passengers choose the transit route just based on estimated travel times of each transit route. However, travel times of transit routes are uncertain due to many random factors, such as signal failure, bad weathers etc. So it is important to incorporate both travel time and uncertainty of travel time into the transit equilibrium assignment model. In this paper a risk-averse transit equilibrium assignment model is formulated. Firstly, the late penalty cost function is used to describe the passengers' risk aversion behavior under threatening environment. Then a variation inequality formulation is adopted to capture the transit equilibrium pattern under uncertainty and a diagonal algorithm for the model based on route-specific costs is given. Finally a small transit network is used to illustrate the model and algorithm.
