Signal settings design problem with an analytical approach: Application in an urban area

We report an application for designing signals at junctions in an urban area. The problem formulation connects the gradient evaluation with the path choice model, allowing a robust method to evaluate analytically the derivatives in the gradient projection method based on C-Logit model. The application is developed in the central area of Reggio Calabria, designing the signals at some junctions in a system optimum approach. The objective of the procedure is to minimize the energy spend by a vehicle in an urban area with the optimization of the signals at the junction.
