In this study, a novel method of evaluating the impact of straddle monorail noise on residential areas considering both objective and subjective effects was developed, in view of the singleness of the existing evaluation method of the track noise impact on residential areas. Using a questionnaire, the quantified straddle monorail noise data for five typical apartment complexes with rail-side layouts were combined with data on the subjective feelings of residents regarding this noise. Then, a model for evaluating the impact of the straddle monorail noise on residential areas under subjective and objective conditions was constructed. Finally, by considering the impacts of straddle monorail noise in residential areas, prevention and control measures were proposed that targeted the acoustic source, sound propagation process, and receiving location. The proposed evaluation method, which considered the needs of residents, could be used to improve straddle monorail noise impact evaluation systems and provide a scientific reference for improving acoustic environments in residential areas along straddle monorail lines.

This study focuses on the psychological characteristics and empirically tests of the factors influencing distracted driving behaviours. This information is used as a reference for an intervention on dangerous driving behaviours. First, a distracted driving scale is constructed based on the theory of planned behaviour (TPB). The questionnaires are distributed in Chongqing, China, and 321 completed questionnaires are obtained. Data are analyzed using mean-variance analysis, one-way ANOVA, T-test, and multivariate test by SPSS 26.0 to determine the significance of distracted behaviours and demographic variables. We use a structural equation model to determine the path coefficients of each latent variable. Finally, we select the drivers with high tendency of distraction from the results of the questionnaires, conduct a four-stage rational emotional behaviour therapy (REBT) experiment, and use a repeated measures ANOVA analysis to test the validity and persistence of the intervention method. Results show that subjective norm is the most influential psychological factor. There are significant differences between the experimental group (2.38, SD = 0.41) and the control group (2.89, SD = 0.40) in the scores of distractions. This indicates that the distracted behaviour intervention achieves adequate validity and consistency. Educational research on distracted driving behaviour can help identify and correct drivers with high distraction tendency.
