Research Cooperative Systems
The department is pioneering new autonomous mobility solutions by researching, designing, and demonstrating connection, automation, cooperation, and coordination for vehicles, system networks, and us humans.
LTSA – Local Traffic Safety Analyzer
The Local Traffic Safety Analyzer (LTSA) detects and analyses both the carriageway and the side of the road on the infrastructure side and provides movement lines (trajectories) and messages to describe the situation for road users. The product consists of a sensor and a data processing component. In the future, it can be used to support automated and networked road users. In the short term, it can already be used for innovative approaches to traffic information and control, so that traffic flow can be improved and road safety increased with the help of the LTSA. The focus here is on vulnerable road users (VRU), such as cyclists and pedestrians.
Within the project, the product prototype of the LTSA is being researched and developed, which in particular records the vulnerable road users (VRU) in the road space. The work of the DLR Institute of Transportation Systems is to support the project participant VITRONIC (lead) in the development of the LTSA at the level of road user detection. The main task of the Institute of Transportation Systems is the transfer of the LTSA data (trajectories and point clouds) and their processing for and utilisation in the innovative VITAL control procedures for traffic signal systems. At the traffic control level, the LTSA as a recording system and the VITAL procedures as control components are therefore coupled with each other. In particular, the aim is to improve control with regard to the needs of pedestrians and cyclists. Furthermore, the Institute of Transportation Systems is supporting the development of the output of V2I information in relation to critical traffic situations by the LTSA to increase road safety in automated and networked driving and in the smart city context.
The product to be developed, called Local Traffic Safety Analyser (LTSA), is an integrated control and environment information system consisting of
- a sensor platform,
- a server with a software application for analysing and monitoring the traffic situation and
- with an interface for implementing communication between the infrastructure and vehicles (V2X) as well as
- an interface for communicating with DLR's VITAL control procedures.
The aim of the project is to develop a marketable prototype (complete system consisting of the above-mentioned components) in conjunction with VITAL to improve traffic flow, increase road safety and support automated and networked driving.

Follow-up project LTSA+
Local Traffic Safety Analyser further development
The overarching project objective is to further develop and optimise the current state of development of the VRU modules as a building block for the adaptive VITAL process and to apply and test them within the LTSA in real traffic. To this end, existing communication and control modules for the VRU are to be revised and new ones integrated so that the VITAL procedure can take into account the requirements of the VRU even more effectively.
Duration:
04/2024 to 10/2025
This project is co-financed by the European Regional Development Fund [EFRE].
