Travel demand analysis and modelling are necessary for evaluating transport infrastructure projects and transport system management strategies. Since transport systems are usually described using network configuration, transport network flow analysis is one of the most important process in the travel demand analysis and modelling. Network flows and the level of service in the network are the resuluts of the interaction between travel demand and system performance. This paper shows the User Equilibrium formulation of network flow applying nonlinear optimization framework. The UE flow model can be incorporated into the system evaluation model of networks under degraded conditions due to natural disasters. The expected value of the consumer's surplus represents the performability measure of the degraded network. An approximation algorithm and numerical examples are presented.
