文摘
- •
A new stochastic user equilibrium model that accounts for correlation in path utilities is proposed.
- •
This is a distributionally robust model that uses mean and covariance information.
- •
It is free of distributional assumptions, in particular, does not assume normality.
- •
An optimization approach is used to find the traffic equilibrium flow values.
- •
Model provides a practical alternative to the probit stochastic user equilibrium.
