Further, positive overconfidence in their capabilities makes efficient compensation difficult. Therefore, understanding the mechanisms of hazardous road crossing by focusing on optimism is important. To examine the mechanisms that influence crossing decisions, this study formulated two opposing hypotheses: more optimistic older adults are blind to functional decline and thus make riskier crossing decisions; less optimistic older adults are more aware of their functional decline and thus avoid risky crossings. Forty-eight older adults aged 65 years or older were asked to come to the laboratory and complete a questionnaire on crossing roads; subsequently, their working memory, attentional shifting, and -inhibition abilities were measured. Data were analyzed using a Bayesian generalized linear mixed model. A model was constructed for each item using four scores on dangerous crossing decisions as the objective variables, allowing examination of the effects of “executive functioning,”“subjective health,”“driving frequency,”“optimism,” and “interaction between optimism and the other variables.” In older adults with low optimism, the poorer the attentional shifting and -inhibition function, the more such hazardous crossings were avoided. In those with high optimism, the lower their subjective health, the more hazardous the crossings. These results supported this study’s hypotheses on optimism. In older adults with low optimism, higher levels of working memory, subjective health, and driving frequency were associated with higher-risk-crossing choices, suggesting that optimism is related to risk avoidance and may influence crossing intentions.","PeriodicalId":517391,"journal":{"name":"Transportation Research Record: Journal of the Transportation Research Board","volume":"53 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141882972","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}

Thick-lift paving is the placement of asphalt concrete in a lift greater than the allowable maximum by an agency, often four to five times the nominal maximum aggregate size. Thick-lift paving offers potential benefits including streamlining operations and eliminating the bond interface in multi-lift layers. However, it also presents challenges such as potential for inadequate compaction and lower ride quality. Asphalt concrete design and construction specifications from 19 state Departments of Transportation were reviewed. In the field, 28 thick-paving test sections were constructed with different lift thicknesses (3 to 10 in.), two mix designs, different paving screed settings, and different rolling patterns. All pavers were equipped with tamper bar screeds. During construction, the researchers monitored asphalt cooldown time and mat density. After construction, the ride quality of each section was measured, and cores were tested for air voids content. Acceptable mat compaction was achieved in all test sections, with additional roller passes having the most significant effect on compaction. The study also found that thick one-lift layers yielded better and more uniform compaction than two-lift layers. Thicker lifts had significantly longer cool down times and potentially increased roughness. Recommendations included the possible use of tamper bar screeds and additional roller passes to improve compaction. Scenarios that are suitable for thick-lift paving were identified.","PeriodicalId":517391,"journal":{"name":"Transportation Research Record: Journal of the Transportation Research Board","volume":"364 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141882975","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}

Although BSSs have gained traction in the business-to-business domain, their acceptance in the business-to-customer sector remains uncertain. This study leverages the Unified Theory of Acceptance and Use of Technology 2 (UTAUT2) combined with a structural equation modeling framework to discern the adoption intentions toward BSS among individual drivers. Drawing from a survey of 434 EMV users in Jiangsu Province, China, we analyzed the relationship between latent variables, while also evaluating the moderating effects of sociodemographic and transport-related factors via multi-group analysis. The findings revealed a model with impressive explanatory power, accounting for approximately 54.8% of the variance in intention. Notably, social influence emerged as the most potent influencer on intention, trailed by effortlessness expectancy, price sensitivity, and performance expectancy. Intriguingly, both price sensitivity and technology anxiety exhibited a negative correlation with intention. Furthermore, variables such as gender, age, income, riding purpose, and riding frequency were found to significantly shape users’ intentions to embrace BSS. This research offers valuable insights for policy makers aiming to promote BSS adoption among EMV users and encourage the EMV market’s growth and sustainability.","PeriodicalId":517391,"journal":{"name":"Transportation Research Record: Journal of the Transportation Research Board","volume":"98 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141882971","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}

The ANN algorithm is independent of correlation assumptions as it uses prior cases/instances to grasp the relationship. A database of eighty pile load tests on squared precast/prestressed concrete (PPC) driven piles and corresponding CPT data was prepared in this regard, in which the ANN models were trained using these data. Feed-forward network techniques such as backpropagation algorithm, Levenberg–Marquardt algorithm were used with trial and error. The cone sleeve friction and corrected cone tip resistance were used to train numerous ANN models. A comparison was made between the prediction of ANN models and three pile-CPT methods, that is, Laboratoire central des pontes et chaussées (LCPC), probabilistic, and University of Florida (UF) methods. The findings of this research exhibited that ANN excels in the evaluation of ultimate capacity of squared PPC piles. A comparison was also made with LCPC, probabilistic, and UF method on the basis of reliability-based load and resistance factor design analysis, which also demonstrates higher resistance factors, ϕ, and superior efficiencies of ANN models over the traditional pile-CPT methods. Consequently, these discoveries reinforce the efficacy of utilizing ANN for assessing the ultimate load-bearing capacity of piles through the interpretation of CPT data.","PeriodicalId":517391,"journal":{"name":"Transportation Research Record: Journal of the Transportation Research Board","volume":"187 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141882973","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}

Bus transport in particular is considered to be a reliable mode of transport. In cooperation with a city’s transport company, we process in this article data collected from two fleets of buses. The data records are related to the failures of individual bus subsystems. We focus on the study of data from engine and brake subsystems, the consequences of failures of which are the most serious in relation to traffic safety. The data are seemingly austere, as the records only contain information such as “operating/fault” during a given month (no known causes, mechanisms, or other more precise time information about the failure). On the basis of such sparse data, however, it is still possible to estimate the trend or predict the development of certain measures over time. For the study and subsequent prediction, we used approaches based on state space models. Specifically, we worked with a linear trend model and a periodic component model. For both fleets of buses, we have also analyzed what the respective model and its prediction could look like if we knew selected and more detailed time information about the failures. This model therefore provides a general idea of the rate of occurrence of failure trend development, expected number of failures within single months, and respective bus subsystem failure occurrence forecasts. Based on this information, operators and entrepreneurs can rationalize the processes related to operations, maintenance, and repair planning.","PeriodicalId":517391,"journal":{"name":"Transportation Research Record: Journal of the Transportation Research Board","volume":"34 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141883048","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}

Inert filler does not react with asphalt, whereas active filler actively participates in a chemical reaction with asphalt. This study utilized a viscosity grade (VG)-30 asphalt, basalt stone dust (B), hydrated lime (HL), and nano hydrated lime (NHL) as fillers for asphalt-filler mastic preparation. The dosages of HL and NHL fillers were varied as 0%, 5%, 10%, 15%, and 20% by weight of VG-30. Filler/binder ratios of 0.6 to 1.2 were considered with different filler combinations (B, B-HL, B-NHL) for the production of 36 mastic types. The high-temperature performance of the asphalt-filler mastic was investigated using shear creep and multiple creep-recovery tests. Further, this study evaluated the properties of the fillers which were most influential on the permanent deformation behavior of mastic using grey relational analysis. The findings signify the beneficial effects of NHL over HL in improving the ability of mastic to withstand permanent deformation. Also, mastic treated with NHL was found to be less susceptible to high stress levels than mastic treated with HL. It was also found that the amount of active filler can be reduced by 5% (by weight of asphalt) by using NHL instead of HL to achieve the equivalent high-temperature performance of mastic. Specific surface area and average particle size were found to be the most two influential properties of filler that significantly influenced the high-temperature performance of the asphalt-filler mastic.","PeriodicalId":517391,"journal":{"name":"Transportation Research Record: Journal of the Transportation Research Board","volume":"22 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141883051","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}

However, manual data entry in the tool is labor intensive. Thus, a more automated method is needed for large data sets. This study developed deep-learning models to automate the classification of crash types. Additionally, the PBCAT’s classification typology can lead to imbalanced data sets, underscoring the need to actively tackle the issue of imbalanced native classification. By addressing this issue, researchers can significantly enhance their ability to harness the potential of emerging large language models. This endeavor becomes even more crucial as large language models like transformer models become increasingly accessible, offering promising opportunities in transportation safety research. This study focused on police reports’ text narratives concerning pedestrian crashes in three major cities in Texas from 2018 to 2020 as a case study. It evaluated the effectiveness of classification loss functions, classification typology adjustments, and model pre-training in addressing the adverse effects of data set imbalance. Our tests indicate that better classification results can be achieved by using the balanced categorical cross entropy (BCE) loss function and using a model with a more robust pre-training. This effect was noticeable when a large enough sample size was present for each class. In the case of smaller data sets, a tiered classification system was recommended, with fewer classes and more distinct text sentiment.","PeriodicalId":517391,"journal":{"name":"Transportation Research Record: Journal of the Transportation Research Board","volume":"31 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141882965","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}

When freezing air temperatures persist inside a tunnel, it causes damage, such as ice formation from leaks and obstruction of drainage flow. The air temperature distribution inside a tunnel is related to the area inside a tunnel, such as tunnel length, cross-section, and so forth. It can be interpreted with a convection mechanism. Tunnel length is designed depending on site conditions, and it is complicated to predict freezing air temperature distribution in a tunnel. In this study, the air temperature variation inside a long tunnel was measured in winter, and a heat transfer analysis model was implemented. A double-track railway tunnel model with a half-length ranging from 500 to 5000 m was simulated, and the conditions of freezing temperature distribution inside tunnels were investigated.

It can be modified to conductive asphalt by adding various recyclable and environment-friendly conductive additives in it. Such asphalt can provide smart and multifunctional environmentally sustainable applications in the pavement industry. Its production and performance behavior parameters are, however, yet to be entirely understood. This study presents a review of literature on conductive asphalt using systematic literature review and scientometric analysis techniques to holistically understand conductive asphalt and current research developments in this field. The objective was to perform a critical review and scientometrically characterize the published research studies. Literature was acquired from credible research databases for the study duration from 2009 to 2022, and these were subsequently using the preferred reporting items for systematic reviews and meta-analyses (PRISMA) protocol to identify the most relevant documents. Sixty-two bibliographic articles were consequently selected for the study. Systematic review identified the research themes and techniques adopted in the field of conductive asphalt technology, and the scientometric analysis quantified the characteristics of the articles. VOSViewer was utilized for visualizing the key findings of the quantitative analysis. Development of conductive asphalt has great research potential and improving its piezoresistivity and conductive network is the future research focus of smart asphalt technology. An experimental study was also conducted, and the results were presented. A dataset of 75 Marshall asphalt specimens of various mix proportions was compiled to assess the Marshall parameters, volumetrics, and their electrical resistivity. 60/70 penetration grade bitumen was used along with five waste tire metal fiber based modified asphalt mixes with contents 0%, 0.375%, 0.75%, 1.125%, and 1.5%.

A total of 552 responses were collected using a questionnaire that captured socioeconomic and trip characteristics, satisfaction ratings for SQ attributes, and the personal attitudes of consumers. Factor analysis was used to uncover unobserved latent features and to generate two measurement models: for SQ and for personal attitudes of bus users. Three latent variables (“information, safety and security”, “comfort”, and “accessibility/availability”) were observed that signify SQ. Simultaneously, two latent variables (perceived value, and behavioral intention and involvement) were obtained representing the attitude of customers. A structural equation modeling method was employed to compute interconnections among these variables. Information and safety and security had a major influence on SQ followed by comfort and accessibility/availability. Similarly, perceived value had a greater impact on personal attitudes than that on behavioral intention and involvement. Findings also show that evaluating overall SQ is better explained when consumers rate the service quality of buses after knowing about the various attributes. Findings revealed that the overall satisfaction of customers with bus services was influenced more by SQ-related attributes than by personal attitudes. The study also provided insights into public bus service quality improvements that must be emphasized and enhanced to increase ridership. This understanding of connections among SQ, personal attitudes, and overall satisfaction can assist transit officials in developing effective strategies and investment plans to meet the needs of passengers and boost customer satisfaction with public buses.","PeriodicalId":517391,"journal":{"name":"Transportation Research Record: Journal of the Transportation Research Board","volume":"78 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141873074","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}
