US cities do badly in the study, mostly because of worries about personal safety and crime. The US city in top position is San Francisco, in 28th position; Boston is 34th. “You don’t realize how safe Vienna is until you go abroad,” said Hartlauer. “We also have terrific public transport – the underground trains run 24 hours at weekends and it only costs €1 per trip.”
What is one reason why the Viennese public transport system is good, according to Hartlauer?
The subway is cheap to ride The trains run 24 hours a day, every day It is very safe The stations are clean and orderly
