A £2 charge could be applied to non-Cardiff residents who drive into the Welsh city as part of a 10-year plan to reduce congestion and improve air quality.
Following a consultation with thousands of city residents, health and transport experts, Cardiff Council officially unveiled its plans in its Transport White Paper.
The document lists a series of projects designed to transform public transport options in Cardiff and the region, including new tram and train routes, £1 bus fares and improved cycle networks.
Proposals suggest the plan’s £2bn cost could be part-funded by charging motorists who drive into the city, but could include an exemption for Cardiff residents.
The charge could come in by 2024 and the charging zone boundaries are currently under discussion.
Caro Wild, cabinet member for strategic planning and transport, said: “We need to get people out of cars and on to public transport.
“To do that we need to give them the best public transport options. And to do that we need to raise money to pay for them.
“As part of a robust decision making process we will consider a number of options.
“Our preferred option would include an exemption for Cardiff residents from any charge,”
Figures show 50% of people are still commuting to Cardiff in cars, with 30% walking or cycling and 20% using public transport.
