Traffic Flow

A traffic flow survey is used to survey traffic flows within a closed area, also known as cordon. The basis for this are cross-sectional counts where vehicles with license plates are recognized by BCAs. The images and license plates are only processed on the device and linked to traffic flows using a hashing algorithm, fully GDPR compliant. Source, destination and transit traffic as well as traffic flows at selective nodes or relationships are available for data analysis. Traffic flows can be segmented by traffic classification, travel time and origin by country and region.

The following steps are required to carry out a survey:

Products

At least one BCA must be used to record one license plate per cross-section. Observe the installation instructions during installation.

Configuration

The BCAs used must be configured in the Control Center as following.

• MQTT connection "Data Center" aktivated

  
• Use following configurations under "Model & Event Triggers"

  • Model: Traffic&Parking (Standard)

  • Add a Counting Line

  • Global Settings/ Numberplate detection mode: Traffic Flow

  

Now continue with the configuration of the traffic flow survey in the Data Center.

Data analysis

Data analysis takes place in the Data Center.
