Transport in Melbourne, the state capital of Victoria, Australia, consists of several interlinking modes. Melbourne is a hub for intercity, intracity and regional travel. Road-based transport accounts for most trips across many parts of the city, facilitated by Australia's largest freeway network. Public transport, including the world's largest tram network, trains and buses, also forms a key part of the transport system. Other dominant modes include walking, cycling and commercial-passenger vehicle services such as taxis.
