There are practical measures under the panoply of urban vehicle access regulations (UVARs) used to stimulate sustainable mobility behaviour changes in the urban population and reduce reliance on passenger car travel. However, the adoption and implementation of such measures are often riddled with challenges, particularly building public acceptability and preserving social justice. Overcoming these challenges will also require cities to understand how the mobility needs of residents change over time. Considering the limitations of conventional data-collection and monitoring approaches, this study explored and analysed the public perception of UVARs over 12 years through natural language processing techniques using social media as a data source. The results show that UVARs are a prominent topic in public discussion and that the average sentiment expressed in tweets tended to be more positive than negative, with a gradual increase observed over the 12-year study period. In addition, the patterns observed in the data and the topics modelled were consistent with the events and talking points in society related to UVARs. Hence, this study demonstrates that social media data can help policymakers assess public sentiments during the ideation, design, implementation, and operational phases of UVARs and other transport policy measures.","PeriodicalId":45193,"journal":{"name":"Transport Problems","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48222786","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Participants (N=2,808) were part of a multisite investigation of college student drinking across 10 universities in 8 states in the U.S. who reported past-month drinking. Results of a structural equation model testing all possible indirect associations simultaneously indicated that one-third (20 out of 60) of the indirect associations were statistically significant (p<.01). Facets with higher scores representing higher impulsivity (negative/positive urgency) were negatively associated with more internalized motives (autonomous motivation and introjected regulation) and positively associated with less internalized motives (external regulation and amotivation) for drinking responsibly. Facets with higher scores representing lower impulsivity (perseverance and premeditation) demonstrated opposite patterns of associations with motives for drinking responsibly. In turn, more internalized motives were related to higher frequency of protective behavioral strategies use, lower alcohol use severity, and fewer negative alcohol-related consequences; less internalized motives demonstrated an opposite pattern of associations with these alcohol outcomes. The present findings should be replicated using experimental and longitudinal studies for appropriately testing mediation but offer support for a novel hypothesis for motivational pathways from impulsivity to alcohol outcomes that may provide insight into intervention targets.","PeriodicalId":45193,"journal":{"name":"Transport Problems","volume":"11 1","pages":"313-320"},"PeriodicalIF":2.9,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10671234/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89845004","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Especially, the approach assessment of the influence of track geometry monitoring on railway infrastructure processing. The well-timed maintenance of the arrangement of railway tracks in allowable conditions is sufficient for the smooth and steady running of rail vehicles. The mechanism of track gauge widening during exploitation is usually gradual and relatively long-lasting. When are not detected in a timely manner, the final track failures often arise under the effect of additional factors, such as surpassed train speed limit, poorly maintained and functioning running gear of a rail vehicle, misalignment of rails, and extreme dynamical effects. A questionnaire considering the influence of the application of track geometry monitoring was formulated. An expert review was completed in order to perform a comparative analysis of the features of track geometry monitoring with the greatest influence on railway infrastructure maintenance processing. The data collected from respondents were processed using a multi-criterion estimation method, especially an interactive fuzzy linear assignment method. Finally, basic conclusions and considerations are given.","PeriodicalId":45193,"journal":{"name":"Transport Problems","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41861892","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is proposed to carry out sand-fixing works during rainy periods or after preliminary moistening of the sandy surface in order to intensify and reduce the cost of sand-fixing works. The substantiation is carried out on the example of some of the approved and recommended binders based on the express method of studying the possibility of their application to obtain a polymer sandy protective crust on wet sand. The emerging defensive hull is characterized by resistance to wind-sand stream and evaluated by plastic quality and thickness. The impregnation of damp sand with a smaller sum of cover than dry sand is related to an alteration within the nature of impregnation from gravity to capillary. With a decrease in the specific surface of the bulk material and an increase in the pore space, gravitational forces are predominant. The process of wet sand impregnation is associated with the acceleration of the adsorption of the dispersed phase and a reduction in the hole covered due to the partial occupation of the interpore space with water. As a result, in wet sand, the depth of sand impregnation with the binder increases at a lower consumption per unit volume of sand. The following has been established: the possibility of impregnation of approved and recommended binders into wet sand, the inverse dependence of the binder concentration in emulsion forms on the humidity of the sandy surface, the time of application of various binders after moistening the sand and the possible savings of binders.","PeriodicalId":45193,"journal":{"name":"Transport Problems","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47094248","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
