In the networked and highly automated traffic of the future, there will be road users who are not digitally connected to the other participants. In the projectVIDETEC tested by the German Aerospace Center (DLR) together with the project partner IMSTnew technologies to capture these people. In a two-day field test, the DLR scientists set up and investigate a controlled intersection environment. “To ensure safety at intersections, people who are not networked must be reliably identified from an intelligent infrastructure,” explains Dr. Fabian de Ponte Müller from theDLR Institute for Communication and Navigation and project manager from VIDETEC.
Test track at the DLR
When trying to detect people and vehicles that are particularly at risk in road traffic, conventional vehicle environment sensors quickly reach their limits. This is due to highly complex environments, such as those found at some road junctions, especially in urban areas.
The DLR researchers have the eFence for this-Technology developed. This is based on the fact that V2X radio signals, which are actually broadcast for communication, are also used for localization. For this purpose, the employees of the VIDETEC project installed a transmitting antenna and four receiving antennas at an intersection. These record the signals that are shadowed, reflected and distorted by the buildings and road users. IMST also place four microdoppler radars at the intersection to identify and classify road users. In doing so, the researchers concentrate on traffic scenarios that pose a high risk potential, such as turning right on a cycle path. The jointly recorded data are then examined and evaluated. The first preliminary tests have already been successful. The goal is,
Background to the project
The project is from BMVI from the program mFundfunded with 100,000 euros. It has a term of five months and ends on June 30, 2021. The DLR (project management) and IMST GmbH are carrying out this project together. In particular, IMST produces high-frequency circuits, radio modules and communication systems and is involved in VIDETEC with the microdoppler radar system.
