However, the waste crumb rubber modified asphalt has some disadvantages such as poor storage stability, high viscosity and high construction temperature requirement, which restricts the application of crumb rubber modified asphalt in road engineering. In order to improve the storage stability and construction workability of waste crumb rubber modified asphalt, in this paper hydrogen peroxide is adopted for the surface oxidation treatment of waste crumb rubber, to prepare five kinds of hydrogen peroxide treated waste crumb rubber modified asphalt with waste crumb rubber dosage of 15%, 20%, 25%, 30%, and 35% (wt%). The pavement performance was studied by conventional performance tests and rheological properties tests. Then, the microscopic mechanism was studied by scanning electron microscopy, infrared spectroscopy and thermogravimetric analysis. The results show that the waste crumb rubber becomes fluffy and has a richer pore structure on the surface after hydrogen peroxide treatment, which makes it easier for the light components in the asphalt to penetrate into the waste crumb rubber, and thus promotes its dissolution in asphalt, thereby improving the storage stability, construction workability, and low temperature performance of waste crumb rubber modified asphalt, but reduces the high temperature and elastic properties. At the same time, the surface polarity of activated waste crumb rubber is enhanced, and esterification reaction occurs with carboxyl groups, sulfoxides and acid anhydrides in asphalt, which effectively increases the interface bonding between asphalt and the waste crumb rubber, and further improves the storage stability, construction workability and low temperature performance of the waste crumb rubber modified asphalt. The optimum dosage of waste crumb rubber modified asphalt treated with hydrogen peroxide is 30%.</div></div>","PeriodicalId":47239,"journal":{"name":"Journal of Traffic and Transportation Engineering-English Edition","volume":"12 2","pages":"Pages 331-343"},"PeriodicalIF":7.4,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143887007","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}

However, in the interaction between motorcycles and pedestrians, pedestrians tend to be at a greater risk of injury and death. In safety literature, much research has been dedicated to the study of motor vehicle-motorcycle and motor vehicle-pedestrian crashes, and very little research has been done on motorcycle-pedestrian crashes. This study contributes to efforts to fill in the gap in this important safety area from the perspective of a rapidly developing middle-income country, Ghana, where the growth in motorcycle activities has been exponential over the past few years. To achieve this, motorcycle-pedestrian crash data for Ghana from 2015 to 2019 were obtained from the Ghana National Road Traffic Accident database at the Building and Road Research Institute (BRRI) of the Council for Scientific and Industrial Research (CSIR). After cleaning, a total of 2655 motorcycle-pedestrian crash observations were available for analysis and model estimation. The distribution of crashes by severity shows that 16.69% were fatal, 53.10% were incapacitating injuries, and 30.21% were minor injury crashes. The study adopted the random parameters logit with heterogeneity in means and variances approach to develop an injury severity model to understand how various crash factors influence pedestrian injury outcomes. The model estimation results reveal that pedestrians who were struck while crossing the road were more likely to be killed or seriously injured. The likelihood of fatal injury was found to be high at night and when the motorcyclists bolt after hitting a pedestrian. Speeding was also found to be associated with fatal injury outcome. This study is expected to stimulate conversations in the road safety community to pay attention to this silent safety concern. Ultimately, the findings of the study provide data-driven evidence to support countermeasure development and implementation, using the safe systems approach.</div></div>","PeriodicalId":47239,"journal":{"name":"Journal of Traffic and Transportation Engineering-English Edition","volume":"12 2","pages":"Pages 410-419"},"PeriodicalIF":7.4,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143886805","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}

Different yielding mechanisms and manufacturing materials of metallic dampers are discussed. Finally, the recent progress and application of bridge engineering are summarized. It can be concluded that each section of the torsion-type metallic damper exhibits a uniform stress state and undergoes plastic deformation simultaneously. Therefore, the damper has a strong energy dissipation capacity. Additionally, self-centering metallic dampers can automatically recover to their initial position after suffering an earthquake. Combined metallic dampers can take advantage of different types of dampers, thereby enhancing damping performance. Finally, these dampers will significantly enhance the seismic performance and overall safety of bridge structures. Future research will likely focus on hybrid systems that combine metallic dampers with other energy consumption mechanisms to further improve adaptability and energy dissipation, advancing the resilience and safety of bridge structures.</div></div>","PeriodicalId":47239,"journal":{"name":"Journal of Traffic and Transportation Engineering-English Edition","volume":"12 2","pages":"Pages 236-268"},"PeriodicalIF":7.4,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143887002","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}

Emerging connected vehicle (CV) and/or autonomous vehicle (AV)-generated mobility data can be potentially used as a new data source in support of the adaptive signal control. In the long-run, the CV/AV-generated data source could gradually substitute traditional inductive loop data as the maturity levels of the relevant data process techniques are progressively increasing. However, use of the CV/AV-generated data is still yet mature due to lack of the data process mechanism and models to integrate the data into the adaptive traffic signal control system. It is hence an imperative need to develop the mechanism for processing the CV/AV-generated data source in order to facilitate improving the efficiency of the adaptive traffic signal control schemes. This paper presents a developed methodological framework along with associated data models which can be used to configure an intelligent CV/AV data fusion in support of adaptive signal control operations. A proof-of-concept study has been conducted to test the developed models via comparison of the CV/AV-data-driven scenario and the traditional-detection-data-supported scenarios.

By considering the characteristics of decision variables and models, a variable neighborhood search (VNS)-niched Pareto genetic algorithm (NPGA) approach with a three-stage encoding structure chromosome is proposed, where the VNS algorithm nested in NPGA is used for individual variable neighborhood search to optimize individual channel level genes, and NPGA is adopted to solve the multi-objective optimization model.

To enhance comprehension of bridge temperature issues and mitigate adverse thermal stress and deformation, the fundamental principles of “resistance”, “release”, “prevention”, and “utilization” are summarized based on the causes of thermal effects, which are resisting thermal stress, releasing thermal deformation, preventing temperature actions, and utilizing thermal effects. Subsequently, typical approaches are summarized based on each principle. Under the “resistance” principle, measures such as rational reinforcement design, increasing early concrete strength, and utilizing new materials with high tensile strength can be employed to reduce the risk of structural cracking. Following the “release” principle, techniques like proper arrangement of expansion joints and bearings, flexible foundation design for jointless bridge and mass concrete layering method can be utilized to release thermal deformations. Based on the “prevention” principle, reducing the hydration heat, applying heat-insulating coatings, shading panels, and phase-change materials can decrease temperature differences in the structure. Improved calculation of thermal effects during construction can also aid in construction control. Based on the “utilization” principle, it is possible to strengthen arch bridges and treat expansion joints with the help of favorable thermal effects.

This study aims to estimate the delay time alteration at a simple zebra crossing using on-site measures and simulation. Roadside video recordings were carried out in Budapest, Hungary, to obtain the crossing decisions of pedestrian groups based on the approaching vehicle distance. We have determined the accepted vehicle distance vales for pedestrian groups that served as input data for microsimulation modelling. The novelty of the study is that the simulation involved autonomous vehicles that hold preset headways from the leading vehicle. The simulation was designed based on the traffic share of autonomous vehicles and the headways they kept. The main findings are that the travel time and stopping time for cars are higher if the modal share of autonomous vehicles is high. For pedestrians, however, we found a slight decrease in both travel times and stopping times. Moreover, we have proposed modifications to the simulation software (Vissim) to handle distance-dependent pedestrian decisions and drivers' failure to give priority.
