Mixed-Graph Neural Network for Traffic Flow Prediction by Capturing Dynamic Spatiotemporal Correlations
Traffic flow prediction is a prominent research area in intelligent transportation systems, significantly contributing to urban traffic management and control. Existing methods or models for traffic flow prediction predominantly rely on a fixed-graph structure to capture spatial correlations within a road network. However, the fixed-graph structure can restrict the representation of spatial information due to varying conditions such as time and r…
A Novel Region Similarity Measurement Method Based on Ring Vectors
Spatial distribution similarity analysis has extensive application value in multiple domains including geographic information science, urban planning, and engineering site selection. However, traditional regional similarity analysis methods face three key challenges: high sensitivity to directional changes, limitations in feature interpretability, and insufficient adaptability to multi-type data. Addressing these issues, this paper proposes a rot…

How Teacher Autonomy Support and Emotional Violence Shape Adolescent Achievement Emotions
BACKGROUND: Achievement emotions (e.g., enjoyment, pride, anxiety, boredom) critically influence students' academic engagement and performance. Teachers foster intrinsic motivation and positive achievement emotions by providing autonomy support that fulfills students' psychological needs. In contrast, emotionally abusive teacher behaviors (e.g., sarcasm, belittlement) thwart these needs, leading to negative emotions and academic burnout. This stu…
Unequal disease burdens
Gender differences have a significant impact on disease burden. Although there is extensive research on disease burden in China, the age-related and long-term trends in gender differences for major diseases are not clear. This study analyzes the gender differences in the burden of 20 major diseases in China from 1990 to 2021, revealing temporal and age-related trends, and providing evidence for gender-sensitive public health policies. This study …
A Latent-Factor-Model-Based Approach for Traffic Data Imputation with Road Network Information
With the rapid development of the economy, car ownership has grown rapidly, which causes many traffic problems. In recent years, intelligent transportation systems have been used to solve various traffic problems. To achieve effective and efficient traffic management, intelligent transportation systems need a large amount of complete traffic data. However, the current traffic data collection methods result in different forms of missing data. In t…
Dynamic Weighted Road Network Based Multi-Vehicles Navigation and Evacuation
Many events such as large-scale activities and traffic accidents could cause an increase in vehicle density in an area, which makes the evacuation of vehicles important. However, the existing evacuation methods are not efficient limit to multi-vehicles sequences or destinations. In this paper, we introduce a novel dynamic weighted road network model for route planning. Based on the model, the route planning algorithm can obtain higher search effi…
Skyline-Based Sorting Approach for Rail Transit Stations Visualization
Urban rail transit is an essential part of the urban public transportation system. The reasonable spatial data visualization of urban rail transit stations can provide a more intuitive way for the majority of travelers to arrange travel plans and find destinations. The map service of rail transit stations generated by data visualization has gradually become indispensable information guidance in the rail transit system. The existing map service ic…
The aesthetics of Gannan Hakka architecture in modern housing
The rapid acceleration of societal change has subjected contemporary individuals to prolonged periods of diverse pressures, leading to substantial psychological strain, resulting in anxiety, depression, and compromised mental well-being. Within this context, the home has evolved into a vital refuge for modern individuals, offering both physical and psychological respite. Through experimental intervention, this study examines two distinct resident…
A Novel Traffic Flow Reduction Method Based on Incomplete Vehicle History Spatio-Temporal Trajectory Data
In order to improve the effect of path planning in emergencies, the missing position imputation and velocity restoration in vehicle trajectory provide data support for emergency path planning and analysis. At present, there are many methods to fill in the missing trajectory information, but they basically restore the missing trajectory after analyzing a large number of datasets. However, the trajectory reduction method with few training sets need…
A Novel Trajectory Based Prediction Method for Urban Subway Design
In recent years, with the development of various types of public transportation, they are also more and more closely connected. Among them, subway transportation has become the first choice of major cities. However, the planning of subway stations is very difficult and there are many factors to consider. Besides, few methods for selecting optimal station locations take other public transport in to consideration. In order to study the relationship…
A Novel Heuristic Emergency Path Planning Method Based on Vector Grid Map
Emergency path planning technology is one of the research hotspots of intelligent transportation systems. Due to the complexity of urban road networks and congested road conditions, emergency path planning is very difficult. Road congestion caused by urban emergencies directly affects the original road network structure. In this way, the static weight of the original road network is no longer suitable as the basis for path recommendation. To hand…
Dynamic Grid-Based Spatial Density Visualization and Rail Transit Station Prediction
The urban rail transit stations are an important part of an urban transit system. Scientific and reasonable location of rail transit station can greatly alleviate traffic pressure. The number of people in the surrounding area of a rail transit station is an important factor for site selection. However, it is difficult to obtain the spatial distribution of population, which brings great difficulties in terms of site selection. Due to the large-sca…
