Impact of planned and unplanned incidents on travel time variability


A variety of planned and unplanned incidents contribute to journey time variability. Their expected impact on performance is determined by attributes of the incident (time of occurrence, location, scope, duration), the conditions of the network (congestion level) and scale of the analysis (modes, spatial and temporal). This project seeks to identify the most important relationships between these variables in order to prioritise incident management.

Program type



This research draws on a large dataset of incidents in the NSW transport network and corresponding data on road and transit system performance. In order to be able to predict and value the impact of incidents on the system, it is necessary to identify relationships between system performance and critical attributes. Of particular interest are intermodal relationships that demonstrate integration of the system. The project demonstrate interconnectedness of the NSW transport network and suggest management strategies for transport operators.
