Terminology

Presence, occupancy, saturation, density flow?

Detector logics vs. physical detector

In TLCs, there might be a many-to-many relation between detector logics and physical sensors.

graph LR
DL1 --> S1
DL1 --> S2
DL2 --> S3
DL3 --> S3

Loading

In the current TLC SXL, physical sensors are not defined as RSMP components.

In a sensor, is there a need for detector logics? No, DL is a TLC concept.

Correspondence with TLC SXL

Until we get SXL modules, we will have a bit of duplication between the TLC and then new Sensor SXL.

Classification

Countries use different classifications. This is challenging to handle with a fixed set of attributes. But we could use a single attribute with a hash of categories:

"counts": {
  "cars": 50
  "bikes": 40
  "pedestrians": 30
}

We should have an attribute that clearly indicate the type of classification, e.g sweden, denmark, etc.

Would it be useful to have different levels of classification? E.g.:
default: bicycle, car, truck, bus
detailed: bicycle, cargobikes, large truck, small truck, bus, double bus, tram...

[RazeAntoine]

For information, for classification heres is the criterias used in tolling system in France :

• Véhicule height
• Vehicule weigth
• Number of axles
• Caravan or trailer

Perhaps it would be interesting if it were possible for the sensor to return this information and for the categorization not to be an internal process?
