Measuring urban road network vulnerability using graph theory : the case of Montpellier's road network

Abstract

The urban road network provides spatial access to the city through an overlapping hierarchy, ranging from highways to local access streets. This pattern of network organisation has led to an increased propensity to vulnerability, exposing parts of the city to sharp decreases in accessibility when traffic blockages occur on the main links or at junctions. Our aim is to define road network vulnerability and to measure the road network's exposure to risk. We postulate that the network morphology, structure and level of congestion can be influencing factors. Two vulnerability indices which pinpoint accessibility loss in the city by removing links and vertices one by one, have been developed to assess the network's vulnerability.
L'article traite de la mesure de la vulnérabilité du réseau routier par la théorique des graphes à travers l'évaluation stratégique des liens en situation de blocage.
