• Abstract: Idling vehicle detection (IVD) can be helpful in monitoring and reducing unnecessary idling and can be integrated into real-time systems to address the resulting pollution and harmful products. The previous approach [13], a non-end-to-end model, requires extra user clicks to specify a part of the input, making system deployment more error-prone or even not feasible. In contrast, we introduce an end-to-end joint audio-visual IVD task designed to detect vehicles visually under three states: moving, idling and engine off. Unlike feature co-occurrence task such as audio-visual vehicle tracking, our IVD task addresses complementary features, where labels cannot be determined by a single modality alone. To this end, we propose AVIVD-Net, a novel network that integrates audio and visual features through a bidirectional attention mechanism. AVIVD-Net streamlines the input process by learning a joint feature space, reducing the deployment complexity of previous methods. Additionally, we introduce the AVIVD dataset, which is seven times larger than previous datasets, offering significantly more annotated samples to study the IVD problem. Our model achieves performance comparable to prior approaches, making it suitable for automated deployment. Furthermore, by evaluating AVIVDNet on the feature co-occurrence public dataset MAVD [23], we demonstrate its potential for extension to self-driving vehicle video-camera setups.

  Idling vehicle detection (IVD) supports real-time systems that reduce pollution and emissions by dynamically messaging drivers to curb excess idling behavior. In computer vision, IVD has become an emerging task that leverages video from surveillance cameras and audio from remote microphones to localize and classify vehicles in each frame as moving, idling, or engine-off. We propose AVIVDNetv2, a transformer-based end-to-end detection network. It incorporates a cross-modal transformer with global patch-level learning, a multiscale visual feature fusion module, and decoupled detection heads.
