The best way for government to solve traffic congestion is to provide free public transport 24 hours a day and 7 days a week. Do you agree or disagree?

Congested roads impose economic, environmental, and health costs on cities, so governments are under pressure to make public transport more attractive. I disagree that free public transport around the clock is the best solution, because price is only one barrier to use and unlimited free service may divert money from capacity and reliability.
