Accurate vehicle acceleration prediction is critical for intelligent driving control and energy efficiency management, particularly in environments with complex driving behavior dynamics. This paper proposes a general short-term vehicle acceleration prediction framework that jointly models environmental influence and individual driving behavior. The framework adopts a dual input design by incorporating environmental sequences, constructed from historical traffic variables such as percentile-based speed and acceleration statistics of multiple vehicles at specific spatial locations, capture group-level driving behavior influenced by the traffic environment. In parallel, individual driving behavior sequences represent motion characteristics of the target vehicle prior to the prediction point, reflecting personalized driving styles. These two inputs are processed using an LSTM Seq2Seq model enhanced with an attention mechanism, enabling accurate multi-step acceleration prediction. To demonstrate the effectiveness of the proposed method, an empirical study was conducted using high resolution radar video fused trajectory data collected from the exit section of the Guangzhou Baishi Tunnel. Drivers were clustered into three categories conservative, moderate, and aggressive based on key behavioral indicators, and a dedicated prediction model was trained for each group to account for driver heterogeneity.Experimental results show that the proposed method consistently outperforms four baseline models, yielding a 10.9% improvement in accuracy with the inclusion of historical traffic variables and a 33% improvement with driver classification. Although prediction errors increase with forecast distance, incorporating environment- and behavior-aware features significantly enhances model robustness.
To address the growing demand for smart grid development and enhance the efficiency of energy meter wiring detection in grid metering operations, as well as to overcome the inefficiencies and human errors inherent in traditional manual wiring inspections, this paper proposes an intelligent recognition approach for energy meter wiring based on the YOLOv5 model. This paper collects on-site photos of electric energy meters and constructs and trains a dedicated electric energy meter wiring recognition model to achieve automation of wiring status detection. Experimental results demonstrate the model’s strong performance in energy meter terminal recognition tasks, achieving an accuracy rate of 96%, a recall rate of 99%, and scores of 96% and 49% under the mAP50 and mAP50-95 metrics, respectively. The model is capable of efficiently and accurately identifying both the energy meter terminal number and wire sequence, significantly reducing errors that are common in manual inspections. Additionally, this paper examines the occurrence of misdetections and omissions during the detection process and proposes strategies to enhance detection accuracy by optimizing the network model’s learning capabilities. The study highlights the significant potential of the YOLOv5-based energy meter wiring identification method in improving detection efficiency, reducing labor costs, and ensuring the security of power systems. This approach, particularly in the context of smart grid construction and implementation, is expected to play an increasingly vital role in the future.
