Road network vulnerability-evaluation of measures in ranking damages and developments

Abstract

In this article a practical example on studying vulnerability using the method of the critical scenario and multi-criteria analysis is presented. Giving a simple method to handle reliability related to a certain path, section, link, junction or a whole trip for travelers and operators of urban road networks as users of traffic information systems it would be a huge step forward. The best would be to have one single parameter coming from an engineering calculation or a model, which would mean the same for the user and the engineer, and both of them would be able to use it as it was. Introducing a clear definition of reliability and vulnerability of road networks used by a wide range of applications is of capital importance. This article makes some steps towards achieving this goal.
