This paper proposed a training-based method for wind turbine signal forecasting. This proposed model employs a convolutional network, a long short-term memory network as well as a multi-task learning ideas within a signal frame. This method utilized the convolutional network for exploitation of spatial properties from wind field. As well, the mentioned long short-term memory is used for training dynamic features of the wind field. The ideas stated together have been utilized for modeling the impacts of spatio-dynamic construction of wind field on wind turbine responses of interest. So, we implemented this multi-task training method for forecasting the generated WT energy and demand at the same time through a single forecast method, which is the deep neural-network. Performance of our suggested model is confirmed by a real wind field information that is produced by Large Eddy Simulation. This data also include wind turbine reaction information that is simulated using aero-elastic wind turbine construction analyzing software. The obtained results depict that the suggested method can forecast two outputs with a five-percent error by a so short term prediction, which is shorter than 1 m.

Qiao Jiang, Ying Zhou, Lei Zhang, Kun Li, Huan Li

Summary: This paper improves the pedestrian direction selection process and adjusts the contribution of the density factor and the distance factor to pedestrians' choice of moving direction by introducing a weight factor. The simulation results show that considering only the distance factor leads to congestion, while focusing too much on the density factor makes pedestrians hesitate. Therefore, comprehensively considering the impact of both factors is crucial for improving evacuation efficiency and exit utilization.

Summary: This study investigates how individuals make traffic route choices based on evolutionary dynamics by considering skilled drivers and novice drivers as two distinct populations. The research finds that the evolutionary equilibrium is sensitive to factors such as expected traveling distance, proportion of novice drivers, and unit time cost, while the initial proportion of mixed strategies has minimal effect on the outcome. The work aims to explore an innovative way of incorporating evolutionary game theory into the traffic assignment model.

Analysis and visualization of accidents severity based on LightGBM-TPE

Kun Li, Haocheng Xu, Xiao Liu

Summary: In recent years, road traffic accidents have been receiving increasing attention as a leading cause of accidental deaths across multiple disciplines. Studying the severity of accidents can help identify the causal relationship between different risk factors and road accidents, thereby improving road traffic safety. However, the application of data visualization in traffic safety investigations is still lacking. In this study, we propose a hybrid algorithm called LightGBM-TPE that incorporates data visualization into machine learning to analyze the UK's traffic accidents data in 2017. The algorithm outperforms other typical machine learning algorithms in terms of f1, accuracy, recall, and precision metrics. By calculating the SHAP value of each feature using LightGBM-TPE, we find that Longitude, Latitude, Hour, and Day_of_Week are the four risk factors most closely related to accident severity. The visualization of the data further confirms this conclusion. Overall, our research explores an innovative way to understand and evaluate the importance of features in road traffic accidents, which can contribute to suggesting effective solutions for improving traffic safety.

Improved social force model considering the influence of COVID-19 pandemic: Pedestrian evacuation under regulation

Qiaoru Li, Mingyang Zhao, Zhe Zhang, Kun Li, Liang Chen, Jianlei Zhang

Summary: This paper proposes an improved social force model to explore how system dynamics control collective behavior of pedestrians during pandemics. The study finds that maintaining social distance can promote evacuation efficiency, but it may decrease efficiency when the desired speed is too low. Moreover, the response time and epidemic sensitivity of pedestrians also affect evacuation efficiency. This research helps in formulating relevant evacuation plans to inhibit the spread of COVID-19 without lowering evacuation efficiency.
