This paper addresses whether traffic lights in German cities exhibit systematic discrimination against potentially slower cyclists. Recent literature indicates that female and elderly riders tend to cycle at notably lower speeds compared to other demographic groups. Hence, our analysis centres on waiting times at intersections in six German cities, specifically focusing on these particular groups. GPS trajectories were collected via smartphone apps as part of the CITY CYCLING campaign in 2022. Statistical analysis revealed only minor differences in waiting times between genders at traffic lights. Similar observations were made concerning age groups, except for two categories. Unexpectedly, individuals in age brackets where discrimination was anticipated (<16 and >64 years) experienced shorter waiting times at traffic lights compared to others. When examining waiting events per kilometre, a slightly different scenario emerged: women encountered significantly more waiting instances at traffic lights than men. This, coupled with a marginal disparity in average waiting time, hints at potential avoidance strategies.
