Datasets of various geotechnical surveys in several arrays in the Taipei Basin.

The standard penetration test (SPT), seismic cone penetration test (SCPT), and various in-situ seismic tests are commonly utilized for geotechnical site investigations. The investigated data via these tests are widely adopted to capture site characteristics for geotechnical engineering design. However, site characterizations vary in the above in-situ tests, which leads to uncertainties in the corresponding engineering analysis and design. To address these variabilities, this paper meticulously carried out the above-mentioned geotechnical in-situ tests with rigorous supervision at 13 selected sites in the Taipei Basin, yielding several valuable datasets. The datasets consist of digital investigation data including SPT-N, soil classification, CPT-qc and -fs, and the shear wave velocities (Vs) obtained from different measurements. We believe that these datasets will be beneficial for conducting various calibration studies for different geotechnical investigation methods and the corresponding geotechnical parameters.

Exploring influences on the intention of motorcyclists to drink and ride: An investigation in a fourth-tier city of China.

OBJECTIVE: The analysis of motorcyclists' intention to drink and ride can help reduce the possibility of accidents caused by the relevant behavior of motorcyclists. The main objectives of this study are to identify important factors in motorcyclists' intention to drink and ride and to make some recommendations that could effectively reduce their riding intention after drinking. METHODS: To explore the effects of demographic and psychological variables on motorcyclists' behavioral intention to drink and ride, a questionnaire based on the extended theory of planned behavior was designed. Two hundred and five fully completed questionnaires were collected through a survey in Shaoguan, China. A hierarchical regression model was used to analyze observed data. RESULTS: The final hierarchical regression model explained 37.5% of the variance in intention to drink and ride. While initial tests showed that gender, marital status and age influenced some TPB variables, gender was the only demographic variable found to be significant on the riding intention after drinking alcohol in the hierarchical regression analysis. Among the psychological factors quantified by the extended theory of planned behavior, all factors had significant effects on intention except for risk perception, and subjective norms were the most influential factor. CONCLUSIONS: The extended theory of planned behavior can be well used to examine the factors that influence motorcyclists' intention to drink and ride. A more nuanced understanding of these factors can be found in the results.
