This week’s best city stories explore Dublin’s plans to ban private cars from its city centre, discuss the impact of bus rapid transit (BRT) systems on cities in Pakistan and look at designs to transform Honolulu’s buses into mobile homeless shelters. We’d love to hear your responses to these stories, and any others you’ve read recently, both on Guardian Cities and elsewhere. Just share your thoughts in the comments below. A car-free Dublin? As we recently explored, some cities, especially in Europe, are starting to discourage or even ban private car use. Now Dublin is poised to become the latest city to join the fray. Next City reports that Dublin’s City Council and Ireland’s National Transport Authority have proposed to ban private cars in sections of the city centre, in order to ease traffic problems and make Dublin a more pleasant place to live. The reduction of cars will also free up room for a new tram line, planned for 2017.
