| Research Abstract |
This study proposes two network models which simultaneously estimate the value of travel time and of travel time reliability based on the risk-averse driver's route choice behaviour. The first model is formulated as a utility maximization problem under monotonic and separable link travel times, whereas the second model is formulated as a utility maximization problem under non-monotonic and non-separable link travel times. It is shown that the first model, which addresses independent stochastic capacity, is formulated as an optimization problem with a unique solution. The second model, which addresses both stochastic Origin-Destination (O-D) flow and stochastic link capacity, is formulated as a nonlinear complementary problem. The network models proposed in this study are consistent with those of studies that address the value of travel time and of travel time reliability based on utility maximization behaviour.
