To use the services provided by the state. Consider the implications this would have on the public, the government and their relationship.
Firstly we need to determine by how much the government should increase the fares of public transport; dramatically or in one raise or a gradual increase. Well currently the latter is occurring due to modernisation, the possibility for profit in private companies and the developments of methods of taxation. Therefore I will make the assumption that the government will hypothetically dramatically increase the taxes (this is my impression from the statement).
It will ultimately mean that the governments plan to limit pollutant gases being released and preventing its consequences will be made even more difficult as people may be more inclined to use cars individually. Which may bring worsen climate change. And make roads even more congested with traffic, with normally would be solved by taking a train or a bus.
Metropolitan public transport is basic urban infrastructure. It should be free, and car parks in the city should pay for it. That will:
1. Relieve congestion;
2. Reduce emissions;
3. Increase efficiency, as no time and resources are spent in charging, administering, disputing and enforcing fare payments;
4. Decrease inequality, as the poorer tend to live far from expensive business centres
5. Favour investment in public transport;
6. Reduce space used in the cities by cars;
7. Favour the use of taxis wherever public transport is readily available or unsuitable; and
8. Favour the use of commercial car parks placed around the terminals of the public transport network.
