TP7 Vernetzte Vulnerable Road Users

Connected Vulnerable
Road Users

Key Question

How do connected road users, especially vulnerable road users such as pedestrians, cyclists and scooter riders, move more safely and efficiently in road traffic?


Safe and comfortable on the road – by foot, by bike and by scooter. In order to reach the destination safely and efficiently, different road users are connected with parts of the traffic infrastructure in this sub-project – for example with traffic lights.

Vulnerable road users (VRU), such as pedestrians, cyclists and scooter drivers, are warned of dangerous situations on their smartphones. Standardised interfaces and highly accurate localisation are crucial for this.

Starting Point

In the context of the development of new mobility services (automated vehicles, potentially noiseless electric drives, increased mixing of individual mobility modes), it is important to counter the associated risks of injury to VRUs through targeted measures and to promote the attractiveness and safety of the modes of transport chosen by VRUs. Networking between VRUs and other road users is an important tool for this. The sub-project uses this to increase the safety of VRUs in particular through targeted collision warning services. On the other hand, by providing information from the traffic infrastructure (traffic lights) to VRUs so they can optimise their movement and reach their destination safely and efficiently.


In order to demonstrate the networking between VRUs, vehicles and other transport elements at a realistically reproducible level, but also with a broad and extensive target group, and to be able to derive scalable solution approaches, this sub-project is striving for broad networking. This should cover the different thematic aspects (different road users and means of transport, different traffic infrastructure elements) as well as allowing quantitative resilience (high quantities of traffic infrastructure elements, many real users, especially VRUs). An app is intended to protect particularly vulnerable road users by providing collision warnings and traffic light phase assistants, and to increase the flow of traffic in general and of bicycles and scooters in particular. The project partners will test these features in Hamburg in summer 2021.
