BMA/BMC to control traffic light signaling.
Our BMA with the associated features enables you to communicate with traffic signal systems via relays (potential-free contacts) in combination with the BMC . The following applications can be covered in this way:
"Smart Prio System": Prioritization of certain traffic classes and ensuring smooth traffic behavior in real time (e.g. environmentally sensitive control, public transport registration, such as pedestrians, cyclists, e-scooters through to heavy traffic)
Simplify infrastructure maintenance: Replace multiple induction loops with a single BMA BMC. The installation does not require any excavation work and significantly reduces maintenance costs.

Pixels Per Meter is a unit of measurement used to define the amount of potential image detail a camera provides at a given distance.
>30 PPM (Object classes car, truck)
>60 PPM (object classes person, bicycle, motorbike)
Using the camera parameters defined below ensures that the minimum required PPM value is achieved. Tip: Use the lens calculator from Axis or a generic lens calculator.

Focal length
2.8 mm - 12 mm
Camera mounting - distance to object center
Object classes car, truck:
5-30 m (2.8 mm Focal length)
35-100 m (12 mm Focal length)
Object classes person, bicycle, scooter:
3-12 m (2.8 mm Focal length) 25-50 m (12 mm Focal length)
Camera mounting - mounting height
Up to 10 m
Note: Mounting higher can help to minimize obstruction by large objects.
Camera mounting - vertical angle to the object
<50°
Note: The correct vertical angle to the object should be achieved by setting the correct distance to the vehicle and the optimum mounting height.
0° - 90° Note: An angle of approx. 15° provides better results for classification, as more object details are visible (e.g. wheels, axles, etc.)
Object speed
< 40 km/h

Use cases for traffic scenarios
There are the following main use cases of our technology to better understand the traffic situation in the city, on urban roads and on highways
Use cases for traffic scenarios
How to successfully perform traffic counts on specific urban roads and highways, including the classification of objects according to our (sub)classes. You want to know the traffic situation of an urban road or highway? Our software is the solution to record the number of all objects, broken down by object type (class) and direction.
For this use case, our software provides you with all the information you need for traffic counting. The counts of the vehicles including their classification can be recorded. The counts are divided into two directions (in/out). Furthermore, several counts can be carried out in one camera, e.g. the separate counting of each lane. In addition, it is possible to add a second counting line, calibrate the distance between them and estimate the speed of vehicles passing both lines. are recognized by our software.

Camera mounting - horizontal angle to the object
Do you want to know the traffic flow at intersections and traffic circles? The Swarm Perception Platform provides the solution to capture the number of vehicles traveling from an origin zone (origin) to a destination zone (destination), broken down by vehicle type (class).
For this use case, our software provides you with all the necessary data for source-destination traffic analyses - the number of vehicles from one zone to another, including classification according to the standards TLS (technical delivery conditions for route stations) issued by the German Highway Research Institute (BASt).
