The dataset comprises trajectory data of traffic participants, along with traffic light data, current local weather data, air quality data, and road condition data from the Application Platform Intelligent Mobility (AIM) Research Intersection. The trajectory data is indexed by object ID and timestamps, including detailed information about the position, speed, acceleration, dimensions, and classification of each object. The dataset contains 31,405 trajectories, covering both motorized and non-motorized traffic participants. The traffic light data captures the current state of all 30 traffic lights at the intersection. The weather data provide information on wind, sunlight, precipitation, visibility, and more. The air quality data represent concentrations of five different gases and fine particle concentrations in the atmosphere. The road condition data provide information on surface temperature, water layer thickness, and more. For any questions regarding the dataset, please contact opendata-ts@dlr.de. Take a look at the DLR Highway Traffic dataset if you're interested in trajectories up to 6 km long from a German highway.
