Traffic Count Sensor Category

1

Hello all,

First (newbie) post. I am assisting a group of yr 10 school students who wish to develop a RPi based sensor which reports both environmental sensor data, plus measures both quantity and category of passing traffic. Has to be RPi based for educational competition entry.

My question is: can we create a specific data type for traffic-count and vehicle-type which can be used on this platform?

It would be superb if we could correlate timed historic data between PM2.5/10/NO2 and passing vehicles.

Thanks in advance. NMc

Welcome!

There was a traffic sensor here in Germany a few years ago but I can’t remember the name.
There was a kind of AI sytem to recognize cars etc.

It could also maybe done with a big doppler sensor.

The issue is the map is not adapted to full live and moving data. Anyway we could calcute 5min averages.

Thank you! We have no need for real-time data representation. Plan is to have the RPi code to count vehicles and vehicle-type, then present to sensor.community every 5 mins.

Just trying to understand if this is a possibility.

@N_Mc I think it’s possible. But we need to predefine some ‘units‘, i.e. bicycles per minute or cars per minute. Otherwise people would get just a count for something.
These ‘units’ are later shown as ‘value_type‘ in the published json files.
And we need a name for your system, so people can search for that and get an understanding of how the values are determined.
