Set-up Barrierless Parking

How to succeed in setting up a Barrierless Parking Scenario to gather data about utilization
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.

What needs to be considered for a successful analysis?

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.

Configuration settings

Traffic & Parking
Configuration option
CL (Counting Line)
Events for repeated CL crossings
Raw tracks

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).
Toggle direction

Visualize data

You can visualize data via Data Analytics in different widgets.


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


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

Retrieve your data

If you need your data for further local analysis, you have the option to export the data of any created widget as csv file for further processing in Excel.

If you would like to integrate the data in your IT environment, you can use the API. In Data Analytics, you will find a description of the Request to use for retrieving the data of each widget.

(when all environmental, hardware and camera requirements met)
>95% Only vehicles are considered. For parking spaces people, bicycles and motorbikes are not part of our test scenarios as they don't occupy parking spaces.
