As prior research investigated transport network vulnerability at the national level, this study focuses on the transport network vulnerability measurement at the regional level. The Green Triangle Region has been chosen as the case study area due to its location at the Southern end of the border between Victoria and South Australia and mid way between two large metropolitan cities (Adelaide and Melbourne). This research studies road network vulnerability in the Green Triangle Region by using two accessibility indices. The first is the Hansen index which measures the integral accessibility of certain places and the second is the Accessibility/Remoteness Index of Australia which is developed by the Department of Health and Aged Care (DHAC) in terms of measuring remoteness to access the service centre. The next section reviews both the reliability road network and vulnerability road network concept and current research in this field. The following section discusses vulnerability measurement in relation to measure the accessibility indices changes. The next section presents the result and discussion by applying the accessibility approach in road network vulnerability measurement at the Green Triangle Region. The final section includes suggestions for some refinements for further research. (a) For the covering entry of this conference, please see ITRD abstract no. E217541.
