title: UTC STRIDE Project G2: Quantitatively Evaluate Work Zone Driver Behavior Using 2D Imaging, 3D LiDAR, and Artificial Intelligence in Support of Congestion Mitigation Model Calibration and Validation

description: This repository contains the extracted traffic data used in the case study for UTC STRIDE project G2 "Quantitatively Evaluate Work Zone Driver Behavior Using 2D Imaging, 3D LiDAR, and Artificial Intelligence in Support of Congestion Mitigation Model Calibration and Validation". The traffic data was extracted using manual or AI-based methods (presented in the project final report) from two 30-minute videos with high and low traffic density. Below are the description of each data file: <strong>high_density_both_lane_raw_AI_speed.csv</strong> <strong>Description: </strong>extracted individual vehicle speed data of the high traffic density video using the AI-based method. <strong>Data Fields:</strong> object_id: unique id for each detected and tracked vehicle frame_index: frame index of the video when other tracked vehicle exit the virtual speed loop. lane_id: lane id (1=outer lane, 2=inner lane) speed: average speed traveling through the virtual speed loop (kph) <strong>high_density_inner_lane_traffic_AI_count_1min_bin.csv</strong> <strong>Description: </strong>AI extracted count, and speed data on the inner lane of the high traffic density data (aggregated into 1-minute bins) <strong>Data Fields:</strong> time (in min): i th minute in the 30-minute video.
