The Pedestrian Monitoring System Data Visualization [vic.gov.au] consists of a simple, annotated map, but of a relatively novel data source. It shows the hourly counts of pedestrian movements in the city of Melbourne, as captured by the 18 sensors that have been recently installed.
The map conveys the exact count number, as well as the relative difference between the pedestrian volume on the selected day and a relatively normal day. Therefore, one would be able to assess the impact of a specific event on the pedestrian activity in the city.
The visualization aims to offer a better understanding of how people use these precincts so the city could better manage the way they function and plan for future needs. The data is also freely available for those wishing an alternative, and potentially more insightful, representation.
