Network performance analysis for Perth congestion response

Work was undertaken to do a comprehensive network performance analysis (NPA) of the Perth metropolitan road network comprising freeways and key arterials. The resultant analysis reported network performance indicators (NPIs) such as VKT, congestion delay, congested lane-kilometres, travel time reliability and cost of congestion on all major roads, enabling assessment of network performance. The project made use of an array of road and traffic data from multiple sources, including volume data from freeway vehicle detection stations (VDS), SCATS traffic signal detectors and the Perth Regional Operation Model (ROM). Of most significance was the sourcing of average hourly travel speeds across the network from probe data. Through use of Geographical Information Systems (GIS), average hourly volumes and speeds on all roads were integrated together in a GIS map layer of the road network and used to calculate the indicators. This paper presents an overview of the analysis and results from this study, demonstrating how probe data combined with data from other sources can be used to provide useful insights to inform investment decision making in addressing urban congestion at a network level.
