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.

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 |
0°-45° 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 |
Possible Camera for this use case
