By analysing the patterns of light usage a model of human movement and occupation can be established. However commercial building operating on automatic lighting, the disconnect between the number of people and the number of lights on and the unavailability of such information during the day weaken the possible depth of information that could be extrapolated from lights in windows. 2b, Yellow Outline - Traffic flows and densities can be used to understand the flows of people into and out of the city. This can be used to get a sense of where people are going and where they are going to. This culminates in an understanding of how people move within and occupy the city. 3. The invisible information of human stocks and flows that can be established through the analysis of traffic patterns over time is an important component of understanding what drives human movement within the city, to where and where people are attracted to to spend their time, work and socialise. Understanding where people are coming from and where they are going to can be used to organise more efficient transport networks, particularly in the development of public transport networks. Understanding how and where people spend their time can be used to inform the structure of the city, helping to indicate the mix of recreational, residential, commercial and industrial facilities that could or should be included in a healthy city. Further, this information could enable the formation of a denser, more walkable city as the city could be organised around minimising the distance between 'where people are coming from and where they are going to'.
