DroneTrafficZA2020: A sample dataset of N4 freeway traffic adjacent to Engineering 4.0 in South Africa

Dataset associated with the primary article: Real-time traffic quantization using a mini edge artificial intelligence platform A video sample captured by a DJI Mavic Air on the 28th of July at 11:30 of the N4 freeway located in Pretoria, South Africa, adjacent to the Engineering 4.0 campus. The high-definition video (4K, 29.97fps) is 18 minutes and 45 seconds in length (2020718_Mavic_Air_4K.mp4). The second video is a cropped version (1220x560 px) used for the analysis (20200728_Mavir_Air_Cropped.mp4). The analysis involves: (1) generating a ground truth dataset of every vehicle (either a "car" or "truck") entering the frame; only vehicles travelling West (moving right-to-left) toward Hatfield is considered. The dataset contains both the frame number the vehicle is first observed and its associated class, and (2) automatic object detection and counting of vehicles as processed by OpenDataCam. Both the ground truth (groundTruth.csv) and inference (OpenDataCam.csv) dataset is provided in a CSV file format. The line counter configuration file from OpenDataCam (line_counter_config.json) is provided to aid reproducibility. The Python script (ProcessOpenDataCam.py) to process the data is also provided. OpenDataCam, with the correct threshold settings of the AI network, manages to count vehicles to within a 5% accurarcy.
