Introduction GHD were engaged by City of Hobart to undertake an assessment of the performance of the Campbell Street corridor to ensure the feasibility of any proposed change in use of the road space. The assessment is required to provide an understanding of all transport modes, their operational and performance needs, how they impact on road capacity and the reliability of travel. In addition to the assessment of the performance of the Campbell Street corridor, the City of Hobart also requires an assessment of: Liverpool Street between the Railway roundabout and Argyle Street. Bathurst Street between the Railway roundabout and Argyle Street. Argyle Street between Liverpool Street and Brisbane Street. 1.1 Background During the reconstruction of the Royal Hobart Hospital (2016 – 2019), the traffic carrying capacity of Campbell Street was reduced from three lanes to two lanes, between Liverpool Street and Collins Street. The third lane was used as an access lane to support construction activities and was not available to general traffic. As the works at the Hospital are approaching completion, City of Hobart are preparing to regain the full road space and the potential use for the third lane. 1.2 Network aspirations The City of Hobart is considering the potential future use of the third, currently closed, lane on Campbell Street, with an aim of utilising this space for a larger purpose other than providing more capacity for cars. The future function of the Campbell Street corridor is influenced by the following characteristics: Anecdotally the Department of State Growth indicated that during construction of the Royal Hobart Hospital, a decrease in traffic flow occurred on Campbell Street. There is an anticipated rise in pedestrian activity due the presence of new and existing pedestrian generators (such as the Royal Hobart Hospital, the new UTAS Performing Arts Centre, the Theatre Royal, the University’s Medical Science
