The end user can visualize the crowding information by accessing the “STToolkit Crowding Dashboard” on Grafana, the data visualization platform of the STToolkit. This dashboard contains several panels that allows users to visualize the crowding data collected by the crowd sensors, deployed at several hotspots.
Open a web browser and enter the following URL:
<CLOUD_SERVER_IP_ADDRESS>:3000
The <cloud_server_ip_address> is the IP address of the STToolkit’s Cloud Server, where the data visualization application is installed.
A log in screen appears. Insert the username and password credentials provided by the STToolkit Operator to enter Grafana, the STToolkit's data visualization platform.
Username: (provided by the STToolkit Operator)
Password: (provided by the STToolkit Operator)
When logged in, you will be directed to the Grafana Main Menu.
On the left-side menu, click Dashboards and then on STToolkit Crowding Dashboard.
You will enter on the “STToolkit Crowding Visualization” dashboard. You can now visualize the crowding data using this dashboard.
A snapshot of a crowd-monitoring dashboard is shown below.
The 'Sensors' panel shows the general information of the system. It shows:
The last record sent by each sensor;
The name of the sensor;
The number of detected devices in the last record of each sensor.
This panel allows a quick interpertation of the system status and operation.
The ‘Crowding Geodistribution’ panel allows users to assess the crowding-geodistribution in real-time at the several locations where the sensors are deployed.
The locations where the sensor are deployed are shown with a heatmap circle, and are accompanied by the name of the sensor and also the number of detected devices in the last measurement sent by each sensor.
The ‘Sensors Comparison’ graph shows the last crowding measurements sent by the sensors, allowing users to compare crowding between locations and analyze past gathered data.
Use the 'Sensor' button on the top left corner of the dashboard to select the sensors from which you wish to visualize the crowding measurements. The time range for this graph is selected on the top right corner of the dashboard.
The dashboard also contains panels with the maximum crowding levels in different time periods (yesterday, last 3 days, and last week).
It allows users to directly obtain these metrics without the need of using the graph.
Users can visualize this dashboard either in a computer, tablet, or mobile phone. The dashboard is rendered properly regardless the device.
