Electronic Tolling on the Sydney Harbour Crossing

Over 250,000 vehicles per day cross Sydney Harbor by the Sydney Harbor Bridge and Sydney Harbor Tunnel to the Sydney central business district. These two facilities are tolled in the southbound direction via a variety of collection methods that cover cash and electronic tag identification. The Roads and Traffic Authority of New South Wales, Australia, the administrator of the Bridge and Tunnel, decided to move toward electronic only collection on the tunnel. This paper reports on the monitoring and assessment of the incremental increase of electronic tolling on the Sydney Harbor Bridge and Tunnel. It looks at the efficiency of electronic toll collection, automated collection and manual collection and how these efficiencies change with the different mixes of tolling types. It also looks at the dynamic interaction of the various tolling regimes and their impact on capacity of the Bridge and Tunnel having regard to the complex time of day tidal flow management. The assessment involved the use of a sophisticated micro simulation model built in Paramics, utilizing a number of purpose written Application Programming Interface (API) modules in order to model toll payment types, toll plaza driver behavior and tidal lane management. This involved simulating the three toll plazas with four different toll collection types covering their individual time collection distributions. This crossing is tidal flow managed and the model had to simulate the impact of the ten overhead gantries and 20 moveable medians that dynamically manage road space during the peak periods. The use of the model successfully enabled the development of a phased implementation program.
