The dataset for DATA 2022 paper "Dataset: An Indoor Smart Traffic Dataset and Data Collection System" This archive contains a traffic light dataset that can be used for traffic light detection/classification. The dataset is collected from an indoor smart traffic testbed. In this testbed, we use fences to simulate the road's boundaries and use movable toy traffic signs and traffic lights to simulate those in real-world traffic scenes. An F1TENTH vehicle drives along the fence autonomously. Two cameras are mounted on both sides of the vehicle, which capture images of traffic lights and traffic signs on both sides of the track. This dataset contains 3507 images captured by the F1TENTH vehicle. Each image comes with ground truth bounding boxes that enclose the traffic lights and a label indicating the current state of the traffic light, 0 for a green light and 1 for a red light.
