The cost of public transport in Rome is set to rise from 1 Nov, when the first price increases in a decade come into effect. The cost of the most popular ticket, the BIT (biglietto integrato a tempo), which entitles you to 75 minutes' travel on all forms of public transport including one journey by metro, will rise from 0.77 to 1. An ordinary monthly pass will jump from 25.80 to 30, and the price of an annual ticket will rise from 186 to 230. However, a discounted annual pass will be introduced for the under-20s, students up to the age of 26 and members of low-income families at a cost of 150. Children under 10, of whom there are an estimated 260,000 in Rome, will continue to travel free. Public transport tickets sold before 1 Nov will be valid until 30 March 2004, and annual passes bought before 1 Nov will be valid for a year as normal. The price rises are being introduced to help reduce the debts of public transport authority Atac.
