Set-up Traffic Counting

You want to know the traffic situation of an urban street or highway? SWARM software is providing the solution to get the number of vehicles passing at the street split per vehicle type (Classes) and direction.
What data can be generated? 
For this use case, SWARM software is providing you with any data needed for traffic counting - The counts of vehicles including classification can be covered. The counts are split between two directions (IN/OUT). Furthermore, several counts can be made in one video camera, e.g.: count each lane separately. On top, you have the opportunity to add a second counting line, calibrate the distance in between and estimate the speed of the vehicles passing both lines. 
All SWARM classes are detected.

​Pixels per Meter (PPM)​
Pixels Per Meter is a measurement used to define the amount of potential image detail that a camera offers at a given distance.
> 30 PPM (vehicle)
> 60 PPM (rider, person)
Using the camera parameters defined below ensures to achieve the minimum required PPM value)
Tip: Use the Axis lens calculator or generic lens calculator.

The configuration of the solution can be managed centrally in SWARM Control Center. Below, you can see how a standard traffic counting 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?
For receiving the best accuracy of the counting including the classification, the Counting Line 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. 
You can choose the direction IN/OUT as you want in order to retrieve the data as needed.
