Nowadays, public space in our city is too crowded with advertisements to gain commercial value in a short time. The depressive feelings given by enormous and shining billboards makes advertising less attractive for pedestrians; while rational street furniture design is always ignored, which could benefit our city in the long term. Although it is not wrong to earn money in commercial furniture, a fantastic layout of different kinds of furniture can attract more pedestrians and realize city economic growth. On this application, the design of street furniture is not necessarily exclusive to urban designers or architects. Everybody can also propose their own idea of public space and find better solutions to change a specific portion of street. Our target is to provide such a kind of street simulation platform that formulate rational evaluating systems and provide great interaction for users that can really change our street from digital screen to real world.
