Forwarding data to Bulgarian BG Toll system with flespi

Easily tweak the telemetry messages with the data required by the Bulgarian toll road system.

BG Toll: who should care?

National toll road systems launch in different countries across Europe as well as across the globe. Bulgaria is no exception.

The National Toll Administration of Bulgaria is in control of the forthcoming implementation of an electronic system for collection of road charges on a distance traveled basis for vehicles with a total technically permissible maximum mass over 3,5 tons (toll) and on a time basis for light vehicles with total technically permissible maximum mass up to or equal to 3,5 tons (electronic vignette). The system starts its operation on March 1, 2020.

BG Toll (aka "БГТОЛ") requires several parameters to be sent for each eligible vehicle — pan number, vehicle license plate number, vehicle axles count, and vehicle weight.

What flespi can do for you is append the data required by BG Toll to the telematics messages from your selected devices via a special plugin and forward the resulting messages to the BG Toll system via a dedicated stream. Let’s see what needs to be done.

Configuring TollBG plugin for devices

If you point device directly to flespi
If you retranslate device data from Wialon
  • Make sure you have the proper channel created and the tracker pointing to the channel’s IP:port.
  • Create the flespi device of the appropriate device type, enter the IMEI into the ident field.

  • Create a flespi channel of the wialon_reltranslator type.

  • Point your Wialon units to the above channel’s IP:port via Wialon Retranslator protocol (don’t change the original Unit ID).

  • Configure proper retranslator in Wialon (you can add multiple units if necessary).

  • Click on the flespi channel and navigate to the Toolbox tab to make sure the data is coming to flespi.

  • Create the flespi device of the appropriate device type, enter the Device ID from Wialon into the ident field.

  • Open the created device card, navigate to the Plugins tab, and add the TollBG plugin. The plugin will take care of adding the parameters required by the TollBG system into the original device messages.

add flespi plugin tollbg

  • Enter the Pan number and Vehicle license plate number (required) and optionally Vehicle axles count and Vehicle weight. Click Save.

Configuring TollBG stream

create tollbg stream flespi

  • Create a stream of the tollbg type

  • Enter your TollBG username and password in the stream configuration (you should register with the tollbg.eu service to get the credentials). Click Save.

  • Open the stream card and navigate to the Devices tab to assign devices to the stream (so that the stream knows which particular devices to forward data from).

  • The stream card should turn green indicating that the connection is established. This means that new messages from the devices with enabled tollbg plugin will be sent to the BG Toll system.

  • Monitor the message sending process in the logs on the stream Toolbox tab — all issues with authentication and dispatching will pop up there.

Note: all the above operations can also be performed via flespi REST API.

As a result of the simple steps above, any Bulgarian business involved in transportation can automate the process of sending the required data to the national BG Toll system and rest assured that they comply with the latest regulations.
