Optimization for a special class of traffic flow models: Combinatorial and continuous approaches

Abstract

In this article, we discuss the optimization of a linearized traffic flow network model based on conservation laws. We present two solution approaches. One relies on the classical Lagrangian formalism (or adjoint calculus), whereas another one uses a discrete mixed-integer framework. We show how both approaches are related to each other. Numerical experiments are accompanied to show the quality of solutions. © American Institute of Mathematical Sciences.
