Research

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.

The im of the research is to ensure that the methodological approach meets the required quality standards in accordance with scientific principles, so that the revised SUPerNOVa 2.0 traffic model is optimally suited for future applications. To this end, it is planned to build on the principles of the guidelines “Quality assurance of traffic models” (RVS 02.01.31), which is currently being drafted, and to develop and apply indicators for quality assessment.

mobiSwitch is an end-to-end digital, automated, do-it-yourself tool for corporate mobility management. It captures organization-specific mobility needs and behavioral data, supports evidence-based analysis and interpretation, and provides behavior-oriented solutions that enable companies to autonomously organize and govern their mobility in an environmentally sustainable and effective manner. mobiSwitch can be easily integrated into any enterprise ERP or MaaS platform, offers a holistic view of corporate mobility, and delivers key performance indicators (KPIs) and benchmarks for reporting and monitoring. With this project, we aim to develop and test an initial functional prototype that comprises all core modules of an analytics and planning tool for corporate mobility management. These include: data acquisition on mobility behavior and data processing; a firm-specific behavioral and impact model; a catalog of measures with associated impact assessment; and an interactive results interface for visualizing intervention effects and reporting key metrics (time, cost, CO2). In addition, the prototype will be integrable into any MaaS platform via a code snippet or similar mechanism.
