Set-up Traffic Counting with speed estimates

How to succeed in traffic counting including speed estimates of vehicles according to our Classes/Subclasses on dedicated urban & highway streets

Do you want to know the average speed of your traffic in given areas? SWARM software is providing the solution to get the number of vehicles passing at the street split in different speed segments (10km/h) or even see the average speed of the given count over an aggregated time period.

What data can be generated?

For this use case, SWARM software is providing you with any data needed for traffic counting as explained in the Traffic counting use case.

What needs to be considered for a successful analysis?

Find detailed information about camera requirements/settings as well as camera positioning in the table below.

Recommended

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 for object classes car, truck

> 60 PPM for object classes person, bicycle, motorbike

Using the camera parameters defined below ensures to achieve the minimum required PPM value)

Tip: Use the Axis lens calculator or generic lens calculator.

Camera video resolution

1280×720 pixel

Camera video protocol/codec

RTSP/H264

Camera Focal Length

2,8mm-12mm

Camera mounting - distance to object center

Object classes car, truck

5-30 meters (2,8mm focal length)

35-100 meters (12mm focal length)

Object classes person, bicycle, scooter

3-12 meters (2,8mm focal length)

25-50 meters (12mm focal length)

Camera mounting height

Up to 10 meters

Note: Higher mounting is preferred to minimize occlusions from larger objects like trucks

Camera mounting - vertical angle to the object

<50°

Note: setting the correct distance to vehicle and camera mounting height should result in the correct vertical angle to the vehicle

Camera mounting - horizontal angle to the object

0° - 90° Note: An angle of about 15° provides better classification results due to more visible object details (e.g. wheels/axes)

Wide Dynamic Range

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 configure the speed line?

When you have enabled the speed estimation, the Counting Line will transform into two lines with a distance calibration measurement. In order to get a good result on speed estimates it is crucial that the calibration distance between the two speed lines is accurate. The distance can be changed in the trigger settings on the left sidebar.

You can choose the direction IN/OUT as you want in order to retrieve the data as needed. On top, you have the option to give a custom direction name for the IN and OUT directions.
