The best city improvements in 2015: share your stories of good news

From cycling infrastructure to community projects, what's been your city's greatest achievement this year - and what would you like to see change in 2016?

There's no doubt that cities around the world are facing serious social, economic and environmental issues - from inequality and gentrification to air pollution and flooding. But we'd love to hear the good news from your city in 2015: what's improving? Are there brilliant community projects bringing your neighbourhood closer together? Has your cycling infrastructure got better? Have car-free initiatives made your streets safer - or green initiatives made them healthier?

Maybe a new public transport link has opened or a great housing project has taken shape. Even if the change hasn't happened yet, perhaps your city has committed to a new policy which could increase sustainability or make life better for more residents. Wherever you live in the world, we want to know what you feel your city's greatest achievement of 2015 is.
