The driver is one of the most important factors in road traffic. Monitoring driver’s driving status can greatly improve safety and operation efficiency urban traffic case multiple modes. Fatigue has a significant impact on drivers’ road, particularly while monotonous environment for long time. In this study, eye movement parameters 36 drivers were collected through simulation experiment simulator. pupil area percentage closure (PERCLOS) scenes expressway low-grade rural combined with...
In order to modify the porous interfacial transition zone (ITZ) microstructure of concrete more efficiently, a method coating aggregate surfaces by using several nanoparticles was evaluated in this study. The compressive strength, chloride penetration sound, and pre-loading samples were assessed relation type materials used (slag, nano-CaCO3, nano-SiO2) designed thickness (5, 10, 15 μm). ITZ quantitatively determined via Backscattered electron (BSE) image analysis. Results showed that...
This study evaluates the effect of vehicle-bridge coupled vibration on mechanical properties fiber-reinforced magnesium phosphate cement (FR-MPC) composites and bonding repaired systems. By means compressive flexural bond strengths, fiber pullout, mercury intrusion porosimeter (MIP) backscattered electron imaging (BSE) analysis, an enhanced insight was gained into evolution FR-MPC performance before after vibration. Experimental results showed that strength increased when it subjected to...
Although the importance of interfacial transition zone (ITZ) to sulfate attack is obvious, relation between ITZ and rate degradation still unclear. The impact volume content on concrete, including length, mass, elastic dynamic modulus (Ed) variation, fully immersed in magnesium solution were investigated this work. microstructure was analyzed by backscattered electron imaging (BSE) energy dispersive X-ray spectroscopy (EDX) mapping analysis. performance concrete exposed highly depended...
The surface and cross section morphology of rayon-based carbon fibers (RCF) the resulting activated (RACF) were investigated through scanning electron microscopy atomic force microscopy. It was found that RCF exhibited grooves striations with width ranging from 30 to 90 nm, striation distribution about 25 bars per µm around circumference. While on RACF, lots pores emerged superficial (about 1 ~ 2 surface), namely, external porosity but interior close-grained. detected pore sizes ranged 50...
Pedestrian safety is a primary traffic issue in urban environment. The use of modern sensing technologies to improve pedestrian has remained an active research topic for years. applications and difficulties automated detection were investigated, the existing such as piezoelectric sensor, infrared ultrasonic microwave radar, laser scanner computer vision assessed their suitability detection, advantages limitations analyzed. As any one particular type technology may have meeting all necessary...
Within the urban road system, traffic conflicts most frequently are concentrated at intersections, and left-turning is a prominent pivotal factor leading to intersection conflicts. The scarcity of applied models that can comprehensively elucidate shifting trajectory dynamics exit lane selection behavior vehicles has posed challenges accurate analysis prediction vehicle conflict patterns. This study extracted trajectories intersections from video data. A left-turn model was formulated,...
Humidity in the air can significantly limit adsorption capacity of porous materials used for removal chemical warfare agents (CWAs). Therefore, this work, we prepared a organic material (C-1) and its fluoride derivative (C-1-F) via Schiff base reaction determined their structure morphological properties, hydrophobicity, capacity. Compared to parent C-1 material, both channel particle surface C-1-F were highly hydrophobic, thus stabilizing fluorinated under various humidity conditions....
Abstract Under the urban road system, most frequent locations for traffic accidents are concentrated at intersections, where left-turning is one of direct and important factors causing intersection conflicts. There relatively few applied models that can effectively explain trajectory change characteristics exit lane selection behavior vehicles, making it more difficult to achieve accurate analysis prediction vehicle conflict behavior. This study extracted trajectories vehicles based on video...
For carbon emission reduction by ports and shipping lines under sea-and-land transportation mode, to build a two-stage supply chain model consisting of two competing one line The profit functions were established analyze the impact parameters which are port level, unit cost proportion shared on handling pricing, portcalls respective profits. results show that level have significant decision variables Conversely, there is no lines. Within certain range, pricing increases as increase. On...
