The survey was carried out in Ingolstadt at an intersection triangle: Location 1 is the intersection of Friedrich-Ebert-Straße and Goethestraße, location 2 is the intersection of Goethestraße and Schillerstraße, and location 3 is the intersection of Schillerstraße and Friedrich-Ebert-Straße, as shown in Figure 1 A. The surveys were conducted over three consecutive days from Tuesday, July 4 to Thursday, July 6, 2023. During this period, there were no holidays or public events, ensuring usual traffic conditions. The weather conditions were consistently sunny. Data was collected on all days during a roughly three-hour period between 4pm and 7pm to capture the peak traffic volume. Over the three days, a total of 75,000 trajectories were recorded, of which approximately 8,000 were from cyclists and pedestrians each, as depicted in Figure 1 B.

Two drones were used at each location due to the limited flight time of the drones caused by the battery capacity. The drones were each supposed to perform a transition with a temporal overlap in order to obtain a continuous image of the trajectories. However, due to technical problems at the beginning of each video, as well as sometimes missing reference objects to connect the videos and meta data loss regarding the time stamps, it was not always possible to generate continuous timelines. The available, individual recordings of the drones per location and day, as well as the coherent timelines based on them, are shown as an overview in Figure 2.
