Set-up Traffic Counting with speed estimates

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

Recommended

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)

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

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.

Visualize data

You can visualize data via Data Analytics in different widgets.

Scenario

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

Example

Here is an example for a Traffic counting widget split by 10km/h groups of speed estimates. You have different options to choose the data you want for a certain time period.

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.
