Rail transit system is vulnerable to various natural or human-induced accidents. In general, network vulnerability of urban rail transit system reflects the functionality loss after network disruption under system failure, which should be guaranteed and taken into consideration in planning stage. This study proposes to identify the optimal corridor of a new metro line by considering vulnerability characteristics. A quantitative evaluation approach was developed to evaluate metro network considering various disruption scenarios, in which traffic related information, such as O-D demands, was incorporated. In addition to vulnerability characteristics, three other essential objectives were considered in rail transit corridor assignment, namely average travel distance, total ridership and construction cost. Detailed information on geology, population, and land use pattern were introduced with the assistance of Geographic Information Systems software. Finally, a Tabu Search Algorithm is proposed to find the optimum solution, based on which, metro network in Pudong District is adopted as the case study, so that an optimal metro line corridor was identified for the new line. The results further indicate that network vulnerability consideration can be integrated into the planning of rail transit systems by using the recommended approach.
