5G Cloud-based Traffic Jam Warning

5GCroCo (Fifth Generation Cross-Border Control) is a € 17-million European innovation action launched end of 2018 with the objective to perform 5G connectivity tests and trials for the road environment in real-life scenarios. From 11th until 15th of October the project demonstrates 5G Cloud-based Traffic Jam Warning at the ITS World Congress in Hamburg.

The “Vision Zero” initiatives across the world, including the European Union, pursue the goal of no deadly road accidents. Up-to-date and precise warnings about traffic jam endings in conjunction with reliable communication technology can therefore be a service that significantly improves road traffic safety and minimize the risk of severe accidents. At the ITS World Congress 2021 in Hamburg the 5GCroCo Consortium shows how anonymized status data transmitted from the vehicles to the cloud allows to determine the end of the traffic jam in real-time and transmit precise hazard warnings to approaching vehicles.

It is part of the overall “Anticipated Cooperative Collision Avoidance” use case that was developed and evaluated within the 5GCroCo project. This, and the two other use cases with “Tele-operated Driving” and “High Definition Map Generation and Distribution for Automated Vehicles” will be demonstrated in a press event on the 21st of October at the Metz-Merzig-Luxembourg 5G cross-border test and trial site.     

At the beginning of the September members of 5GCroCo team joined at Huawei premises in Munich to continue  with the second round of tests and trials.


5GCroCo has just released its "Tests and Trials Video at Small Scale Sites", recorded during the first round of tests and trials. The video can be watched here. Please subscribe to our YouTube Channel.

Next Monday 6th September at 12:00 CE, it will take place 5GCroCo Webseminar on Security Guidelines for MQTT Protocols, presented by Erik Wegscheider.



MQTT stands for “Message Queuing Telemetry Transport”. This protocol was designed 1999 for machine-to-machine telemetry in low bandwidth environments for TCP/IP networks. MQTT started as a proprietary protocol, it was released Royalty free in 2010 and became OASIS standard in 2014. MQTT was fast becoming one of the main protocols of IOT (internet of things) deployments. MQTT v3.1.1 is in Common Use, the new version MQTT v5 has been approved in Jan 2018 and is currently in Limit use. This web-seminar gives an overview of security threats and common vulnerability patterns of the MQTT v3.1.1 protocol if you don’t use today’s state-of-the-art security features of TCP/IP. The web-seminar shows methods to put security into MQTT v3.1.1 protocol and pinpoints the advantages and disadvantages for each case that will be discussed. The target audience of this web-seminar are developers with a good understanding of TCP/IP and MQTT-protocol. As preparation we suggest reading Section 4.5.2 of 5GCroCo Deliverable D3.2
