This picture is taken by me in a place called "Hong Ya Dong" in the city centre of Chongqing. The information that is visible in this photo is buildings, cars, pedestrians，and some restraurants and pubs in a complex buidling, as well as some light that is classic style in the complex building and digital and modern style in the building righthan-side. What we can extract out from these visible information is the traffic flow, pedestrian flow, the concentration of vehicle emission within the area, how many and when people visited specific restraurants and pubs which lead to citizen behavior and taste, what is the most visited palce and what is the reason for that place to become most popular, what are the popuses for these pedestrians on the street, are they local or tourist, possibily can also make a survey on income of these pedestrians then compare with other areas and so on...... What we can do from these information extracted? 1.The concentration of vehicle emission within the area? If the value is comparatively higher than other area, then the policy maker should do something like limit the amount of cars and promote public transportations, or plant more greens than other areas. 2.What is the income of these pedestrians? The value should been made accompany with survey from other area, which give some group of people valuable information like shop owner and potential investers, if this survey been done constantly, it also gives a dynamic sense about the income change of consumer flow, so shop owners can change their business strategy dynamically.
