On performance sensitivity of urban transportation networks

Abstract

This paper on the performance sensitivity of urban transportation networks is from the proceedings of 14th International Conference on Urban Transport and the Environment in the 21st Century, which was held in Malta in 2008. The authors blame the continuous increase in traffic on increasing numbers of vehicles using a common infrastructure, leading to traffic congestion whenever mobility demand exceeds the infrastructure capacity. They outline a set of selection criteria to help in resource planning and in decision making, based on a sensitivity matrix computed for an a-priori chosen transportation performance index. The paper concludes with a simple case study that utilizes the proposed methodology for selecting interventions in urban transportation networks.
