This study examines the effects of driver behavior on the safety performance of RLCs (within a 150-meter radius) in New South Wales, Australia. Historical databases on crashes, train operations, and inventory for RLCs were integrated. Also, vehicle movement raw data, including acceleration, deceleration, G-force, and speed, were extracted using the connected vehicle data. Then, the driver’s harsh braking and stiff steering events were identified. A random effect Hurdle Poisson model was adopted to account for the excessive zeros and unobserved heterogeneity. We identified risk factors affecting the likelihood and number of crashes at RLCs across two severity levels. Results of the non-injury crashes suggested that street, active control types, harsh braking, and stiff steering were associated with a higher likelihood of zero crash observations, while train frequency showed the opposite effect. It was also revealed that multiple tracks contributed to the increase in the number of non-injury crashes. Interestingly, after crossing the hurdle, harsh braking at RLC is associated with more non-injury crashes. As for the injury crashes, active control and stiff steering were associated with a higher likelihood of observing zeros. Nevertheless, once crossed the hurdle, intersecting with a highway, having multiple rail tracks and harsh braking events show increasing effects on the frequency of injury crashes. The findings of this study emphasize the need for targeted driver education programs and a larger-scale implementation of active control measures. It is hoped that these actionable insights can assist policymakers in prioritizing safety interventions at RLCs.</div></div>","PeriodicalId":51534,"journal":{"name":"Travel Behaviour and Society","volume":"39 ","pages":"Article 100957"},"PeriodicalIF":5.1,"publicationDate":"2024-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142684354","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Following this purpose, we developed a novel methodology that aims at evaluating priority areas for shared micromobility system users’ accident risk mitigation based on predicted injury severity using a machine learning-based approach. The methodology proposed in this paper consists of two models: a predictive model, which is based on an artificial neural network with a pattern recognition algorithm, to estimate the expected safety indicator of an urban zone, and a clustering method to define the priority areas for intervention through the application of a geofence speed regulation system. A real case study was carried out in the city of Bari, Italy, to test the effectiveness of the proposed methodology. The results showed how it is possible to define areas for intervention with different priorities based on the expected severity index. The proposed methodology can be seen as a decision support system to assist transport operators and urban planners in regulating shared micromobility vehicles in urban areas by defining priority areas for intervention through geofencing and, therefore, it can be useful for improving micromobility adoption, road safety, and urban mobility policies.</div></div>","PeriodicalId":51534,"journal":{"name":"Travel Behaviour and Society","volume":"39 ","pages":"Article 100962"},"PeriodicalIF":5.1,"publicationDate":"2024-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142684356","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By contrast, the availability of publicly accessible charging stations at the time of the purchase of a vehicle plays a very small role. Households that own EVs exhibit similar trip mode choices as households that own exclusively internal combustion engine (ICE) cars, drive their EVs similar distances—overall and for specific purposes—and at similar times of the day or night.

However, the potential negative implications of high rates of car ownership and use for wellbeing, sustainability, and social equity have sparked the interest of many scholars. We contribute to these lines of inquiry by examining whether and if so, how car dependence relates to people’s satisfaction with life. Our data come from a national survey with a representative sample (n = 2,155) of U.S. adults living in urban and suburban areas. Using descriptive statistics and multivariate regression models, we find that there is a threshold effect of car dependence on life satisfaction. Our results show that beyond a certain point, increases in car dependence yield a decrease in people’s satisfaction with life. For instance, we find that, in a typical week, relying on a car for more than 50 percent of the time for out-of-home activities is associated with a decrease in life satisfaction. These findings suggest that planners and decision-makers should promote multimodality and land use patterns that may help to reduce car dependence and its potential negative effect on subjective wellbeing (SWB).</div></div>","PeriodicalId":51534,"journal":{"name":"Travel Behaviour and Society","volume":"39 ","pages":"Article 100954"},"PeriodicalIF":5.1,"publicationDate":"2024-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142684358","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The analysis of adaptations and functions of walking shows the versatility of walking practices in their flexibility and resilience. Walking in a neighbourhood that is attributed high walkability functions as a key mode in everyday coordination.

The clustering approach of K-means++ was employed to classify the instantaneous mass emission value and emission rate under various road types, respectively. A novel identification indicator (i.e., the ratio of change rate and growth rate of instantaneous emissions) was proposed as the basis for dividing each emission state. Subsequently, three matrices (i.e., probability matrix, value matrix, and identification matrix) were constructed to reflect relationships between emission states and emission rates under each road type. Moreover, driving scenarios of CO₂ and NO_X high emission were investigated and compared by machine learning models with SHAP explanation and ordered logistic models. The empirical results indicate that the identification indicators of CO₂ and NO_X high emissions are 2.49 g/s² and 3.66 mg/s² on the freeway, 2.98 g/s² and 2.12 mg/s² on the primary road, and 2.77 g/s² and 2.05 mg/s² on the secondary road. Within the same ranges of driving behavior parameters on the freeway, the occurrence probability of CO₂ high emission state is higher than that of relatively high emission state, while an opposite trend is observed for NO_X emissions. Interestingly, despite NO_X and CO₂ show similar emission characteristics on the primary and secondary road, the driving behaviors corresponding to high emissions of NO_X and CO₂ present significant disparities. Generally, the acceleration is the primary determinant of CO₂ high emissions, while both acceleration and deceleration are significant contributors to NO_X high emissions. The findings of this study recommend that long periods of high-speed travelling should be avoided on the freeway. Frequent and abrupt changes in acceleration and deceleration should be minimized on the primary and secondary road, respectively.</div></div>","PeriodicalId":51534,"journal":{"name":"Travel Behaviour and Society","volume":"39 ","pages":"Article 100960"},"PeriodicalIF":5.1,"publicationDate":"2024-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142663501","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
