london: central zone

The temperature here in Krakow is finally back to normal (below freezing at night, warmer daytime.) Meanwhile, I'm trying to advocate for sustainable transportation in the City. There is a discussion these days in Krakow, whether to introduce a fee for driving into the city. I hope that we can learn from good examples other cities, such as London set. Here, London's Central Zone markings on Kensington High Street. Since its introduction in 2003, London's Congestion Charge has improved traffic safety, transit efficiency and resulted in decrease in pollution.
