On performance sensitivity of urban transportation networks

Abstract

The continuous increase in traffic, intended as interacting vehicles using a common infrastructure, leading to traffic congestion whenever mobility demand exceeds the infrastructure capacity itself, has put into evidence many needs in transportation. In this framework, the choice of the optimal solution is a difficult problem to tackle with, especially when uncertainties are taken into account. Therefore, the main effort of this paper is to define a selection criteria which helps in resource planning and in decision making, based on a sensitivity matrix computed for an a-priori chosen transportation performance index.
