Increased traffic safety by means of intelligent detection and localization technologies

Abstract

The two technologies presented in this paper, "Communication Location Surveillance" (CLS) and radar classification by means of evaluation of micro-Doppler spectra, have been adapted and further developed for use in critical and complex traffic situations. The aim of the joint research activity of DLR and IMST is to detect potentially dangerous traffic situations at an early stage and, in particular, to protect vulnerable road users who do not usually communicate digitally with other road users. This is done by precisely locating road users and recording their direction of movement and speed. On the other hand, it must be possible to classify the participants in order to be able to assess their particular potential danger. Only with an exact situation overview of a traffic situation can predictions be made to assess the danger and possible countermeasures be initiated. This includes, for example, warnings to the participants via acoustic or optical signals, via digital vehicle communication or active intervention in a traffic light control system.
