Set-up Queue Length Detection

How to get insights on traffic congestions in terms of data generation, camera set up and Analytics options.

Next to the traffic frequency at given locations, you are wondering about the length of a queue when traffic congestion is given. In combination with the speed of the detected vehicle, you can get proper insights into the length and speed of the current queue.

What data can be generated?

For this use case, SWARM software is providing you with the most relevant traffic insights - The counts of vehicles including the classification of the SWARM main classes can be covered. 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. By combining this with different Regions of Interest (RoI) you can retrieve the needed insights into traffic congestion.

For traffic frequency, all SWARM main classes can be generated. Depending on the camera settings, we can detect present vehicles up to 70 m.

*The higher the distance of the objects to the camera, the higher the focal length, the higher the dead zone. In order to achieve the needed PPM for the detection of objects (30 PPM, please consider the following illustration and table:

The configuration of the solution can be managed centrally in SWARM Control Center. Below, you can see how the standard is configured for optimal results.

In order to start your configuration, take care that you have configured your camera accordingly.

What should be configured?

In order to receive the counting data including speed as well as the RoIs occupancy, a Counting Line and several RoIs need to be configured as event triggers. Depending on the specific use case and object distance, several triggers might need to be combined.

How to place the event triggers?

In order to receive information on how fast vehicles are driving and how many objects are currently present in a specific region, you need to configure counting lines with speed estimation and generic RoIs.

You can choose the direction IN/OUT as you want in order to retrieve the data as needed and give a custom name to that direction.
