Picodi.com recently released the results of its latest study, as its analysts examined the public transport fares in 45 cities worldwide and compared the transport expenses with local average wages. The study took a look at single ticket prices, as well as monthly passes, which allow for unlimited travel within the city limits, according to the company’s news release. Public transport is completely free for citizens in three out of 45 cities – Luxembourg, the capital of Estonia, Tallinn, and the capital of Malta, Valletta. Among other cities in the study’s ranking, the most expensive single tickets can be found in London ($5.19), Zurich ($4.75), and Oslo ($3.91). On the other hand, the highest prices for monthly passes are paid by citizens of London ($271), Dublin ($166), and New York ($127). When the study compared the monthly pass prices with the average monthly wages, the least favorable ratio can be found in São Paulo, where the monthly access to all means of public transport in the city costs 14.3% of the average wage. Second and third place in terms of cost belongs to Istanbul and London (7.5% and 7.4% of the average wage respectively).
