Set-up Adaptive Traffic Control

Adaptive Traffic Control

Adaptive traffic control enables you to interface with hardware devices like traffic controllers using dry contacts. Use cases and benefits:

'Smart Prio' System: Prioritise certain traffic classes and ensure fluid traffic behavior in real-time (e.g. pedestrians, bicyclists, e-scooters, heavy traffic).
Simplify infrastructure maintenance: Replace multiple induction loops with a single Swarm Perception Box. The installation does not require excavation work, and reduces the maintenance effort/costs.

What needs to be considered for a successful analysis?

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 cars, trucks

> 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

Object classes cars, trucks

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

Can be enabled

The configuration of the solution can be managed centrally in SWARM Control Center. Below, you can see how the 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.

Configuration

Requirements:
- Supported hardware: Quido 4/4, Quido 8/8, Quido 2/16
- Supported event types: Region of Interest (ROI) in combination with rules

All you need to get started: Define a Region of Interest (ROI), define a rule and select which relay output to trigger.

First off, enable IO-device, specify the used Quido device type and the endpoint (IP or hostname).

Rule Configuration

Define at least one ROI and create an associated rule. As long as the rule is valid, the associated Quido relay output is enabled (contact closed). One or more rules can be created for the same ROI.
