Cycling in the Bergische Städtedreieck – SimRa

Project Description The project Sicherheit im Radverkehr (SimRa; engl: Safety in Cycling) by TU Berlin is funded by the Citizen Science initiative. Its goal is to identify main bicycle traffic flows and the hazardous situations that arise during these movements. For this purpose, the Scalable Software Systems developed a tracking app that records GPS data and acceleration sensor data anonymously. In addition to general information about the cyclist (age, gender, experience, …), users are asked after each ride whether a hazardous situation occurred and which type of bicycle was used. The hazard can then be described in more detail (involved road users, type of situation, etc.).

Interactive Accessibility Analysis in Public Transport Using GTFS Data (Part-1)

Data-Driven Accessibility in Public Transport Planning As an initial example of data-driven accessibility analysis in public transport planning, this study presents an evaluation based on timetable data. The analysis relies on data provided in the General Transit Feed Specification (GTFS) format, supplied by the Verkehrsverbund Berlin-Brandenburg under a Creative Commons V3 license. Technical Background Using a spatial grid with a resolution of 100 × 100 meters, travel time isochrones are computed and visualized under defined parameters, such as departure or arrival time, and maximum walking distance. The computation of a single isochrone takes approximately one second, enabling efficient and systematic comparisons between existing (as-is) and planned (target) service scenarios. This analytic approach is particularly effective for identifying accessibility deficits in current timetables and supports evidence-based strategies for developing or updating local public transport plans.
