There are neither cars nor busses in Venice. People here only go on foot or on the water. Big passenger launches – vaporetto - play a part of public transport. They have license plates, routs and unified tickets. Private motor boats are taxis.If you have an emergency need to get to the opposite bank of Canale Grande use gondola-traghetto. Classical Venice gondola is a narrow black boat for romantic rows around Venice for 70 euros per hour. All in all, get ready to have comfortable shoes and money.
