SITRAS is a microscopic traffic simulation model developed at University of New South Wales (UNSW) to simulate urban road networks including incidents of varying types. In 1998 the New South Wales (NSW) Roads and Traffic Authority (RTA) engaged the UNSW to investigate the use of the SITRAS model for incident management. The new RTA Traffic Management Centre (TMC), opened in March 1999, includes a decision support system to assist the TMC staff in selecting the appropriate incident response plan for a given incident scenario. This system requires a set of incident management plans developed for various incident types and locations. The objective of the project is to develop an incident modelling software package to be used in the preparation and investigation of incident management plans by the RTA TMC staff. The project is a cooperative effort by the RTA, the Commonwealth Scientific and Industrial Research Organisation (CSIRO) and UNSW and based on their previously developed traffic network simulators, TRITRAM and SITRAS. In the first phase of the project, a comparative analysis of the Sydney road network (the 'Oxford Street network') was conducted in 1999, in order to draw a first comparison between the TRITRAM and SITRAS models, and to formulate recommendations for further developments of the incident modelling software package. Based on the findings of this study several modifications and improvements were implemented in SITRAS. The model was also enhanced by new features, including (a) an interface to the SCATS software, using standard Internet communication (TCP/IP) protocol, enabling SITRAS to model signalised intersections controlled by the SCATS signal control system; and (b) a model to estimate driver reaction to real-time traffic information provided by Variable Message Signs. This paper presents the findings and conclusions of a second case study. The objective of this study is to demonstrate the benefits of incident simulation in the development of incident management plans. The paper describes the details of the M2 case study, a comparison of the simulation outputs, a summary of the conclusions of the project and some recommendations for further work.
