In view of the tremendous improvements in dynamic performance automobiles and changes composition drivers over past several decades, it is valuable to examine distribution automobile’s lateral acceleration new environments. The accelerations, speeds, trajectory curvatures a passenger car on twelve highways with different design speeds topographies were obtained. By synchronizing, matching, counting, was obtained, level driving comfort estimated. The<mml:math...
Abstract The BaTiO 3 powder was prepared via a solid‐state reaction route. It studied for the degradation of bacterial cells, dye, and pharmaceuticals waste using ultrasonically driven piezocatalytic effect. catalytic behavior poled remarkably increased during ultrasonication (10% E coli survival in 60 minutes). structural damages were illustrated scanning electron micrographs cells which demonstrated morphological manifestations under different conditions. Methylene blue (MB dye),...
Accurate driving risk assessments are essential in vehicle collision avoidance and traffic safety. The uncertainty intentions behavior, coupled with the difficulty accurately predicting future trajectories of vehicles, poses challenges assessing among vehicles. Existing research on assessment has been limited to focusing pre-crashes (e.g., time-to-collision) ignoring impact crash severity risk. Research integrating pre- post-crash is needed assess comprehensively. Therefore, objective this...
The design of passenger-dedicated lane width is essential for freeway reconstruction and expansion projects. However, the technical standard established in China based on trucks. This study aims to propose a calculation method freeways overtaking behavior. Computer vision technology was used extract vehicle trajectories dimensions from videos captured by an unmanned aerial (UAV). Statistical methods such as cumulative frequency statistics, typical percentile statistics regression analysis...
To clarify the operational characteristics and driving risks of urban underground road curves, a real vehicle experiment involving 20 subjects was conducted at Jiefangbei Underground Ring Road in Chongqing. High-precision instruments were utilized to collect data, including speed, lateral acceleration, longitudinal acceleration. Significance tests performed on entering curve deceleration, exiting The driver behavior risk curves evaluated using G-G diagrams, distribution danger points...
In this report, we present Qwen2.5-Omni, an end-to-end multimodal model designed to perceive diverse modalities, including text, images, audio, and video, while simultaneously generating text natural speech responses in a streaming manner. To enable the of information inputs, both audio visual encoders utilize block-wise processing approach. synchronize timestamps video inputs with organize sequentially interleaved manner propose novel position embedding approach, named TMRoPE(Time-aligned...
In this study, to calibrate the acceleration/deceleration rates in operating speed prediction models, driving tests were performed on two-lane mountain highways using passenger cars, and continuous longitudinal acceleration data collected. The of large vehicles such as coaches heavy trucks also measured from roadside. collected used determine cumulative frequency profiles statistical distribution characteristics peak for different types vehicles. Based established correlations, models versus...
This article has studied the correlation relationship between spectral features of polluted leaf surface Ficus microcarpa and air dustfall in Guangzhou City. The results show that reflectance leaves industrial area large traffic is 3-5.5% higher than cleaning visible band, but 10-15% lower near infrared band. Compared to cleaned leaf, on nature dirty 6.6％ band 25.6% difference a strong with city. coefficient 0.821. It simple convenient, fast, economic method monitor using characteristic...
Sloped sections are the basic road units of mountain roadways and often considered as high-risk positions. To verify correlation between slope physiological signals drivers thus acquire mechanism influence parameters on drivers' workload, this study conducted naturalistic driving tests two-lane mountainous roads. The data vertical alignment parameters, electrocardiographic drivers, accelerator/brake pedal forces were collected. distribution force well its relation with heart rate increase...
To understand the public’s acceptance of autonomous vehicles, studies were conducted from perspectives personal attributes, travel demand and cognitions vehicles based on 403 valid questionnaires. Influencing factors whether travelers are purchasing without a driver’s license intend to take in future choosing an private car if can only taxi or drive analyzed by building Logistic regression models. The results show that monthly income, license, driving confidence, preference for convenience...
The most significant assumption of conventional analytical methods (e.g., the subdomain technique) is that stator and rotor iron cores are infinitely permeable. magnetic saturation ignored, resulting in an overestimation flux density. This article presents model permanent magnet (PM) machines with segmented Halbach arrays (PMMSHA). It considers finite permeabilities teeth tooth tips (STTT) can study effect. permeability variation slots solved via Cauchy's product theorem. Based on vector...
The selection of trajectory and speed is a crucial factor in automobile driving behavior. However, almost all the research objects existing Driver models are developed for on city streets general highways but not applicable to simulations minor traffic roads with complex shapes, particular. Therefore, according practical processes characteristics real world, this paper proposed calculation strategy, which we named as "selecting point preview cross section." According objective functions was...
Accurate calculation of magnetic field distribution is a prerequisite for motor design and optimization. This article develops an analytical subdomain model external rotor in-wheel with surface-inset magnets (ERIWMSIMs). Besides, to weaken its torque ripple, improved topology by integrating flux modulation slots (MFMSs) into tooth tips proposed. First, the entire problem divided five subdomains, viz., magnet slots, air gap, stator slot openings, MFMSs. Then, this study solves Laplace's or...
Many small-spacing interchanges (SSI) appear when the density of expressway increases. However, characteristics traffic accidents in SSI have not been explained clearly. Therefore, this paper systematically takes G3001 Xi’an as research object to explore accident SSI. Firstly, is divided into four sections. Furthermore, their safety can be evaluated by number per unit distance 100 million vehicles (NAP). Subsequently, eight indexes, such mean spacing (MSD), are selected explain cause...
