Traffic count, or traffic flow measurement, is the process of obtaining data on the number of people passing by a certain location, e.g., a cafe or a point of sales, for a given period.
Analyzing pedestrian, car, or bicycle traffic helps improve the city infrastructure as part of a smart city initiative. The most accurate way to measure traffic is to take a video of the entrance area and count how many people have passed by in a given period (e.g., an hour or a day).
