Study on bi-level programming model of highway traffic network based on the sustainable development theory

The large-scale highway construction can cause certain influence for environment while satisfying traffic demand. Based on the idea of sustainable development, the tradition one-goal layout optimization model of city highway network is extended. The lower-level model is the stochastic user equilibrium assignment, then according to goals about the economy, society, environment and energy sustainable development, highway traffic network bi-level programming model is established, and the simulation annealing algorithm is designed. This model not only can satisfy the traffic demands, but can also satisfy the goals of the sustainable development.
