Abstract
This thesis investigates how social and technical elements interact to affect bicycle accidents and safety in Leiden, the Netherlands. Despite high cycling rates, Leiden has a higher accident rate than the national average. Structured observations of cyclist behavior are combined with Geographic Information System (GIS) analysis of accident data and cycling infrastructure using a Socio-Technical Systems (STS) framework. The report highlights critical areas for action, showing that 88% of bike accidents happen within 20 meters of junctions and 25% near bus stops. GIS analysis reveals that non-separated infrastructure makes up 62.5% of Leiden's bike network, potentially posing safety risks. Observational data indicates a high incidence of near-miss occurrences and low rates of accurate signaling behavior. The study emphasizes the influence of infrastructure design on cyclist behavior and safety outcomes. Results suggest that cycling safety in Leiden could be significantly improved through targeted upgrades to intersection design, better integration of bicycle infrastructure with public transportation, and increased networks of protected cycleways. This study contributes to the growing body of research on urban cycling safety and provides insights for cities with similar historical urban fabrics.
