On transport network reliability

Abstract

Transport network reliability is defined in relation with the main attributes of the network (e.g. connectivity, topology, state of infrastructure), the traffic characteristics (OD matrices, volume, hourly/day-to-day variations etc.) and with environment interactions (natural event, climatic change). The study of the Romanian national transport network reliability in terms of economic implications, like the growth of the total traveled path induced by functionality/failure of the network components leads to the identification of the road links which, according to the reliability, should be carefully monitored to preserve the attractiveness of the transport network. Using Visum software, the paper presents a methodology to assess the transport network reliability at national level but also useful for urban transport networks.
