Heads-up: Analysis of pedestrians’ attention and crossing behaviour at junctions in the context of the SafeLight system

This project investigates the effectiveness of ground-projected traffic signals for pedestrians (SafeLight) at signal-controlled junctions. The aim is to analyse the system’s influence on pedestrians’ crossing behaviour and attention, as well as on their subjective perception of road safety. To this end, the SafeLight system will be installed at a selected junction and evaluated using a before-and-after study design. The analysis is based on video recordings of the crossing area that comply with data protection regulations, using which behavioural parameters such as compliance with red lights, reaction times when signal phases change, head movements, smartphone use and safety-critical interactions with traffic are systematically coded. In addition, short standardised surveys of pedestrians are conducted to capture subjective perceptions regarding visibility, clarity and perceived safety. Combining objective behavioural data with subjective assessments enables a comprehensive evaluation of the effectiveness and potential of ground-projected traffic signals as a road safety measure. The findings provide a basis for transport planning decisions regarding the future implementation of innovative traffic signal concepts for pedestrian traffic.
