Smart cities is all about how to tackle problems in a city with the use of data and technology. Due to the involvement of technology in how we use said data it is very important to know the boundaries of the things that are essential for smart cities to work, data. Data can be gathered from many different sources and can direct us in a variety of directions as to what this data means, but depending on what data is gathered and how it is interpreted may change the outcome of the actions based on them.
Take for example Waze which allows users to see other user data of their speed in a certain area. We can take this information as this certain area has congested traffic due to an anomaly or high traffic times. That is only one approach but when you take more data in a bigger scope a different approach may be how can user traffic data can tell us how the city can change road infrastructure to allow for better handling of traffic. like changing an intersection or stoplights sincronization.
