Set-up Barrierless Parking

You have a parking space where you simply want to know your utilization by making an Entry/Exit count, SWARM provides a perfect solution for doing that quite easily. See yourself:
What data can be generated? 
For this use case, SWARM software is providing you with any relevant data for your Entry/Exit parking space. The solution is gathering the number of vehicles in your parking space as well as the number of vehicles entering and exiting your parking space for customizable time frames.
The vehicles are classified in any classes the SWARM software can detect. Nevertheless, consider that the following configuration set-up is optimized to detect vehicles and not people and bicycles.

The configuration of the solution can be managed centrally in SWARM Control Center. Below, you can see how the Entry/Exit parking with license plate detection needs to be configured for optimal results. 
In order to start your configuration, take care that you have configured your camera and data configuration.

How to place the configuration type?
To receive the best accuracy in counting including the classification, the CL should be placed approx. in the middle of the video frame so that vehicles from both directions are seen long enough for good detection and classification. 
Consider that the IN/OUT direction of the counting line is important as it is relevant for the calculation of the utilization. (IN = Entry to parking, OUT = Exit of parking).

Visualize data
You can visualize data via Data Analytics in different widgets.

Scenario
In our Parking Scenario section, you can find more details about the possible Widgets to be created in the Parking Scenario Dashboards.

​
Example 
You are able to visualize the data for any Entry/Exit you have configured with the Counting Lines. So you are able to see the number of vehicles with their classes/subclasses that entered or left your parking spot, either aggregated over several Entry/Exits or separately per Entry/Exit. We deliver the following two standard widgets Current & Historic Parking Utilization out of the box when creating a Parking Scenario Dashboard
