In order to understand the current research status and development direction of driving risk identification at home and abroad, relevant literatures in the field of driving risk identification from the China National Knowledge Infra-structure (CNKI) and Web of Science (WOS) in recent 12 years (2011–2022) were selected as research samples, and literature metrology tools VOSviewer and Citespace were used for visual analysis. The situation was analyzed from the aspects of chronological distribution, national cooperation network, distribution of domestic institutions, journal performance and keywords overview, literature coupling clustering and research hotspots. The results show that the number of published papers fluctuates year by year, and China, the United States and Germany have the largest number of published papers. The United States is at the center of international cooperation. The CNKI shows that universities in China such as Chang'an University and Chongqing Jiaotong University have published a large number of documents. According to the statistics of WOS, Accident Analysis & Prevention is the most widely published journal in the world. The average level of the journal is high and the quality of articles is better. Combining the research contents of CNKI and WOS, the main research directions can be clustered into five cluster themes by using the coupling function in VOSviewer, including driving risk assessment considering driver factors, the influence of driving environment on driving risk, driving risk assessment considering multi-source characteristic data, multi-aspect research on driving risk and risk identification of non-traditional vehicles in specific scenarios. Human-machine co-driving, artificial intelligence, intelligent driving, risk identification and natural driving are the current research hotspots and the future research trends.

为了了解国内外驾驶风险识别的研究现状和发展方向,选取中国知网(CNKI)和科学网(WOS)近12年(2011-2022)在驾驶风险识别领域的相关文献作为研究样本,并使用文献计量工具VOSviewer和Citespace进行可视化分析。从时间分布、国家合作网络、国内机构分布、期刊表现和关键词综述、文献耦合聚类和研究热点等方面对情况进行了分析。结果显示,发表论文数量逐年波动,中国、美国和德国的发表论文数量最多。美国是国际合作的中心。中国知网显示,长安大学、重庆交通大学等中国高校发表了大量文献。根据WOS的统计;《预防》是世界上出版最广泛的期刊。该期刊的平均水平较高,文章质量较好。结合CNKI和WOS的研究内容,利用VOSviewer中的耦合函数可以将主要研究方向聚类为五个聚类主题,包括考虑驾驶员因素的驾驶风险评估、驾驶环境对驾驶风险的影响、考虑多源特征数据的驾驶风险评估,多方面研究非传统车辆在特定场景下的驾驶风险和风险识别。人机协同驾驶、人工智能、智能驾驶、风险识别和自然驾驶是当前的研究热点和未来的研究趋势。

Identification of accident black spots has gained tremendous popularity among road agencies and safety specialists for evaluating and subsequently enhancing road traffic safety. However, there is still limited understanding of the internal relationship between black spots and microscopic vehicle kinetic parameters. To address this gap, this paper describes a project that was undertaken using the real-time tire force data (kinetic response) obtained from road experiments on Wenli Expressway. First, factor analysis was applied to extracted three independent indicators (power-braking, handling stability, and ride comfort) from seven original kinetic indicators with multiple collinearities. Afterward, the main indicators were given vehicle kinetic meaning by analyzing the characteristics of original indicators associated with them. A compelling correlation was established among kinetic parameters, vehicle running qualities, and accident risk. Additionally, an integrated evaluation framework was established to identify accident black spots based on applying ordered logit models and PLS-entropy-TOPSIS approaches. The recognition results exhibited that the overall recognition accuracy obtained by the latter was found to be comparable to that achieved using the previous one. The compound evaluation model proposed in this paper has been proven to present many advantages for black spot identification. It is evidently clear from the findings that the vehicle kinetic parameters have significant correlations with road accident risk. This paper could provide some insightful knowledge for identifying and preventing the black spots from ameliorating traffic safety.

事故黑点的识别在道路机构和安全专家中非常受欢迎,用于评估和随后加强道路交通安全。然而,对黑点与微观车辆动力学参数之间的内在关系的理解仍然有限。为了解决这一差距,本文描述了一个利用温里高速公路道路试验获得的实时轮胎力数据(动力学响应)进行的项目。首先,应用因子分析从具有多重共线的七个原始动力学指标中提取三个独立指标(动力制动、操纵稳定性和乘坐舒适性)。然后,通过分析与主要指标相关的原始指标的特征,给出了主要指标的车辆动力学意义。动力学参数、车辆运行质量和事故风险之间建立了令人信服的相关性。此外,在应用有序logit模型和PLS熵TOPSIS方法的基础上,建立了识别事故黑点的综合评价框架。识别结果表明,后者获得的整体识别精度与使用前一种方法获得的识别精度相当。本文提出的复合评价模型已被证明在黑点识别方面具有许多优点。从研究结果中可以明显看出,车辆动力学参数与道路事故风险具有显著相关性。本文可以为识别和预防黑点改善交通安全提供一些有见地的知识。

Based on the four-element model, this paper reviewed the important research progress in vehicle platoon, compared the advantages and disadvantages of different models in each element longitudinally, and summarized the linkage between each element horizontally. The stability criteria are briefly reviewed from three dimensions: local stability, string stability, and traffic flow stability. The impact of communication delay on vehicle platoon is quantitatively summarized from two aspects: the variation of controller gains and the variation of headway time values. Aiming at the inevitable communication delay in vehicle platoon, the compensation strategies are analyzed from five levels. (1) Optimizing the communication network structure. (2) Reconstructing acceleration information. (3) Tuning controller gains. (4) Constructing a multi-branch selection structure. (5) Improving the controller. The results show that, although these compensation strategies can alleviate the negative impact of communication delay to a certain extent, they also have some defects such as difficulty in adapting to complex and various real road conditions, poor accuracy and real-time performance, insufficient security, and limited application scenarios. It is necessary to further improve the accuracy and real-time performance of the device, design an encrypted and scalable network architecture to ensure communication security and adaptability, and conduct further real vehicle testing.

本文在四元模型的基础上,回顾了排车研究的重要进展,纵向比较了不同模型在各个单元中的优缺点,横向总结了各个单元之间的联系。从局部稳定性、串稳定性和交通流稳定性三个维度简要回顾了稳定性准则。从控制器增益的变化和车头时距值的变化两个方面定量总结了通信延迟对车队的影响。针对车队不可避免的通信延迟问题,从五个层面分析了补偿策略。(1) 优化通信网络结构。(2) 正在重建加速度信息。(3) 调节控制器增益。(4) 构建多分支选择结构。(5) 改进控制器。结果表明,这些补偿策略虽然可以在一定程度上缓解通信延迟的负面影响,但也存在难以适应复杂多样的真实路况、准确性和实时性差、安全性不足、应用场景有限等缺陷。需要进一步提高设备的准确性和实时性,设计加密和可扩展的网络架构以确保通信安全性和适应性,并进行进一步的实车测试。

The temperature change caused by hydration leads to early-age cracking in concrete box girder. The early-age cracking risk is further improved with low air temperature and large daily temperature difference, especially in Northwest China. To fill this gap, a temperature experiment and numerical simulation were performed on an actual concrete box girder segment in Northwest China. The temperature field, thermal stress and cracking risk were analyzed using evolution curves, distribution curves and contours. The key parameters that influence the hydration heat temperature, including the cement hydration heat release, cement content, height-width ratio of web, initial temperature, convective coefficient of top plate surface, were analyzed. An anti-cracking case based on parameters analysis was put forward. The results indicated that the temperature evolution can be divided into three stages: warming, cooling and environment significantly impacting. Along the thickness of each plate, temperature distributed is single peak in the center. Along the width or height, temperature distributed is double peaks at axillary position for the top and bottom plates, and single peak in center for the web. The axillary position and web have high thermal stress and significant cracking risks. The temperature difference of each plate, and the early-age cracking risk can be reduced by effectively adjusting the key parameters. Among these, the former two parameters are the most significant factors. The maximum cracking risk can be decreased by 15.7% for every 50 kJ/kg hydration heat reduction. The maximum cracking risk can be decreased by 13.1% for every 50 kg/m3 cement content reduction.

水化引起的温度变化导致混凝土箱梁早期开裂。随着气温低和日温差大,早期开裂风险进一步提高,尤其是在西北地区。为了填补这一空白,在中国西北地区的一个实际混凝土箱梁节段上进行了温度试验和数值模拟。利用演化曲线、分布曲线和等值线分析了温度场、热应力和开裂风险。分析了影响水化热温度的关键参数,包括水泥水化热释放量、水泥含量、腹板高宽比、初始温度、顶板表面对流系数。提出了一个基于参数分析的防裂实例。结果表明,温度演化可分为升温、降温和环境显著影响三个阶段。温度沿各板厚度方向呈单峰分布。沿宽度或高度方向,顶板和底板的温度分布在腋窝位置为双峰,腹板的温度分布为中心单峰。腋窝位置和腹板具有高的热应力和显著的开裂风险。通过有效调整关键参数,可以降低每块板材的温差和早期开裂风险。其中,前两个参数是最重要的因素。水化热每降低50kJ/kg,最大开裂风险可降低15.7%。水泥含量每减少50 kg/m3,最大开裂风险可降低13.1%。

The rapid development of the delivery industry brings convenience to modern society. However, the high rates of crashes and the survival of electric bicycle (e-bike) riders in the delivery industry raise concerns. The primary objective of this study is to explore the factors affecting delivery e-bike riders' stressful work pressure and crash involvement in China. Data were collected by a questionnaire survey administered in the city of Ningbo, China. A bivariate ordered probit (BOP) model was developed to simultaneously examine the factors associated with both the working conditions of delivery e-bike riders and their involvement in crashes. The marginal effects for the contributory factors were calculated to quantify their impacts on the outcomes. The results showed that the BOP model can account for commonly unobserved characteristics of the working conditions and crash involvement of delivery e-bike riders. The BOP model results showed that the stressful working conditions of delivery e-bike riders were affected by the number of orders and delivery time and rider age and risky riding behaviors. Delivery rider involvement in crashes was affected by the number of orders, strength of the punishment for traffic violations, and familiarity with traffic regulations. It was also found that stressful working conditions and crash involvement were strongly and positively correlated. The findings of this study can enhance our understanding of the factors that affect the working conditions and delivery rider crash involvement. Based on the results, some suggestions regarding public policy, risky riding behaviors, safety promotion, and stronger corporate governance rules were discussed to increase the targeted safety-related interventions for delivery e-bike riders in Ningbo, China.

快递业的快速发展给现代社会带来了便利。然而,快递行业的高撞车率和电动自行车骑手的生存引发了人们的担忧。本研究的主要目的是探讨影响中国电动自行车骑手工作压力和撞车事故的因素。数据是通过在中国宁波市进行的问卷调查收集的。开发了一个双变量有序probit(BOP)模型,以同时检查与电动自行车骑手的工作条件和他们参与车祸的相关因素。计算促成因素的边际效应,以量化其对结果的影响。结果表明,BOP模型可以解释送货电动自行车骑手的工作条件和碰撞参与的常见未观察到的特征。BOP模型结果显示,送货电动自行车骑手的压力工作条件受到订单数量、送货时间、骑手年龄和危险骑行行为的影响。快递骑手参与车祸受到订单数量、交通违法处罚力度以及对交通法规的熟悉程度的影响。研究还发现,紧张的工作条件和车祸的发生呈正相关。这项研究的结果可以增强我们对影响工作条件和送货骑手撞车事故的因素的理解。基于研究结果,讨论了一些关于公共政策、风险骑行行为、安全促进和更强有力的公司治理规则的建议,以增加对中国宁波送货电动自行车骑手的有针对性的安全相关干预。

Latex as an asphalt modifier has gained popularity in the asphalt industry as it improves the durability of asphalt pavement. However, the elastomeric properties of latex stiffen the asphalt binders, resulting in additional energy consumption during the production of asphalt mixtures, which may cause a higher emission of greenhouse gases. This is undesirable for sustainable development and the environment. In this study, the applicability of diluted methanol and water was comparatively evaluated as foaming agents in the production of warm mix asphalt (WMA) mixtures incorporating latex. Diluted methanol was used because it has a lower boiling point and latent heat than water, allowing the asphalt mixture to be produced at a lower temperature and thus consuming less energy. The performance of the foamed asphalt mixture was investigated through service characteristics, mechanical performance, and moisture susceptibility of mixtures. The service characteristics, on the other hand, were measured in a laboratory while preparing and compacting the asphalt mixture, which refers to the amount of energy required during the production and construction stages in the asphalt plant and on the construction site, respectively. The degree of energy required was assessed based on the workability index, coatability index, and the compaction energy index. The mechanical performance of asphalt mixtures was characterized by indirect tensile strength, resilient modulus, and dynamic creep tests. The resistance to moisture damage was evaluated based on the common parameter, indirect tensile strength ratio. The findings revealed that the use of diluted methanol foaming agent helped improve the workability of latex modified asphalt mixtures. The foamed latex-modified WMA demonstrated better performance compared to asphalt mixtures prepared using water as the foaming agent.

乳胶作为一种沥青改性剂,由于其提高了沥青路面的耐久性,在沥青行业中越来越受欢迎。然而,乳胶的弹性特性使沥青结合料变硬,导致沥青混合料生产过程中的额外能源消耗,这可能会导致更高的温室气体排放。这对于可持续发展和环境来说是不可取的。在本研究中,比较评价了稀释甲醇和水作为发泡剂在生产掺有乳胶的温拌沥青(WMA)混合物中的适用性。使用稀释的甲醇是因为它比水具有更低的沸点和潜热,从而允许在更低的温度下生产沥青混合物,从而消耗更少的能量。通过混合料的使用特性、力学性能和水分敏感性,研究了泡沫沥青混合料的性能。另一方面,在制备和压实沥青混合料时,在实验室中测量了使用特性,这分别是指沥青厂和施工现场生产和施工阶段所需的能量。所需能量的程度是基于可加工性指数、可涂覆性指数和压实能量指数来评估的。通过间接拉伸强度、弹性模量和动态蠕变试验对沥青混合料的力学性能进行了表征。根据常用参数间接抗拉强度比对其抗湿损伤性能进行了评价。研究结果表明,稀释甲醇发泡剂的使用有助于改善乳胶改性沥青混合料的工作性能。与使用水作为发泡剂制备的沥青混合物相比,发泡胶乳改性的WMA表现出更好的性能。

This is undesirable for sustainable development and the environment. In this study, the applicability of diluted methanol and water was comparatively evaluated as foaming agents in the production of warm mix asphalt (WMA) mixtures incorporating latex. Diluted methanol was used because it has a lower boiling point and latent heat than water, allowing the asphalt mixture to be produced at a lower temperature and thus consuming less energy. The performance of the foamed asphalt mixture was investigated through service characteristics, mechanical performance, and moisture susceptibility of mixtures. The service characteristics, on the other hand, were measured in a laboratory while preparing and compacting the asphalt mixture, which refers to the amount of energy required during the production and construction stages in the asphalt plant and on the construction site, respectively. The degree of energy required was assessed based on the workability index, coatability index, and the compaction energy index. The mechanical performance of asphalt mixtures was characterized by indirect tensile strength, resilient modulus, and dynamic creep tests. The resistance to moisture damage was evaluated based on the common parameter, indirect tensile strength ratio. The findings revealed that the use of diluted methanol foaming agent helped improve the workability of latex modified asphalt mixtures. The foamed latex-modified WMA demonstrated better performance compared to asphalt mixtures prepared using water as the foaming agent.</p></div>","PeriodicalId":47239,"journal":{"name":"Journal of Traffic and Transportation Engineering-English Edition","volume":"10 3","pages":"Pages 413-426"},"PeriodicalIF":7.9,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49792095","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}

Maintaining the health and reliability of civil facilities is of strategic importance. In highway engineering, pavement cracking impairs the road service and travel comfort level, while structure cracking can cause catastrophic damage. Microcapsule-based self-healing materials offer solutions to auto-recovery micro-cracks and maintain structural health. Such solution has become available by laboratory synthesis and proved effective in addressing the cracking problem during long-term mechanical, thermal, and hydraulic conditions. However, full-scale applications of this technique are not prevalent, showing its potential limitations in highway engineering. Crack healing in highways is a big topic, therefore, this review has two insertion points. (1) We focus on the cracking issues on two specific materials: asphalt and concrete, which account for the vast majority of all the materials used in pavement and structures in highways. (2) Instead of the laboratory studies, we pay more attention to the practical applications, the meaning of healing performance, and the adverse effects of microcapsules to the main structural components (i.e., tunnel lining, bridge piers and beams) and pavement in highways. The practical significance of self-healing materials in highway projects was discussed from the three aspects: strength, durability, and stress redistribution. The difficulty in applying this new technique is also discussed from economic perspective. For future-proofing, a material evaluation system that fits the load condition is required. The self-healing technique brings composites a chance to interact with the environment, showing high potential for contributing to the development of various types of long-lasting infrastructures.

维护民用设施的健康和可靠性具有重要的战略意义。在公路工程中,路面开裂会损害道路服务和出行舒适度,而结构开裂会造成灾难性的破坏。基于微胶囊的自修复材料为自动恢复微裂纹和保持结构健康提供了解决方案。这种解决方案已通过实验室合成获得,并被证明在长期的机械、热和水力条件下有效解决了开裂问题。然而,这项技术的全面应用并不普遍,表明其在公路工程中的潜在局限性。高速公路裂缝愈合是一个大课题,因此,本文有两个切入点。(1) 我们关注两种特定材料的开裂问题:沥青和混凝土,这两种材料占公路路面和结构材料的绝大多数。(2) 与实验室研究相比,我们更关注微胶囊的实际应用、愈合性能的意义以及微胶囊对公路主要结构构件(即隧道衬砌、桥墩和梁)和路面的不利影响。从强度、耐久性和应力再分配三个方面论述了自修复材料在公路工程中的实际意义。文中还从经济学角度讨论了应用这一新技术的困难。对于未来的验证,需要一个适合负载条件的材料评估系统。自修复技术为复合材料带来了与环境相互作用的机会,显示出为开发各种类型的持久基础设施做出贡献的巨大潜力。

Marble dust waste powder generated by the marble cutting industry has a high alkalinity. In this research, the use of marble dust (MD) as a mineral filler substitute in hot mixed asphalt (HMA) was evaluated. The Marshall mix design was used to determine the optimum bitumen content (OBC) for all of the mixtures. For each of the four MD contents, i.e., 0, 2%, 4%, and 6% by weight of the total aggregates, four different bitumen percentages were used. The results of the Marshall stability test showed that the optimum filler content was 4% MD. Samples were prepared with 0 MD in the control mix and varying percentages of MD as an alternate filler. In addition, MD aided in increasing the Marshall stability, rutting resistance, and permanent deformation and reduced the fatigue life of asphalt mixtures. As the percentage of MD increases, the rutting resistance and stiffness at high temperatures both increase. As the percentage of MD increases, the fatigue life reduces. Rut resistance in high-temperature conditions can be improved by using MD in HMA as a partial substitute for stone dust (SD). In areas where extensive MD waste is present, MD can be incorporated into HMA mixtures instead of conventional fillers.

大理石切割行业产生的大理石粉尘废渣具有较高的碱度。本研究评价了大理石粉(MD)作为矿物填料替代热拌沥青(HMA)的应用。马歇尔混合料设计用于确定所有混合料的最佳沥青含量(OBC)。对于四种MD含量中的每一种,即总骨料的0、2%、4%和6%重量,使用四种不同的沥青百分比。马歇尔稳定性试验的结果表明,最佳填料含量为4%MD。制备的样品的对照混合物中含有0MD,不同百分比的MD作为替代填料。此外,MD有助于提高马歇尔稳定性、抗车辙性和永久变形性,并降低沥青混合料的疲劳寿命。随着MD百分比的增加,耐车辙性和高温刚度都增加。随着MD百分比的增加,疲劳寿命降低。在HMA中使用MD作为石粉(SD)的部分替代品,可以提高高温条件下的抗车辙性。在存在大量MD废物的地区,MD可以掺入HMA混合物中,而不是传统的填料。

Over the course of storm or rainfall event, water thickness builds up on road surface resulting in a loss of contact between vehicle tires and road surface and puts drivers into immediate danger especially at high speeds. Therefore this is a considerably dangerous condition of the road and the realistic measurements and prediction model of water film thickness (WFT) on pavement surface is crucial for determining the road friction coefficient and evaluating the impact of rainfall on traffic safety. A review of the principle as well as critical evaluation of current detection methods of pavement WFT were compared for consistency and accuracy in this paper. The method selection guidelines are given for different road surface water film thickness detection requirements. This paper also introduces the latest development of WFT detection and prediction models for asphalt pavement, and gives the calculation elements and conditions of different WFT prediction models from different modeling ideas, which provides a basis for the selection and optimization of WFT models for future researchers. This article also suggests a few insights as further research directions on this topic. (1) The research can consider the influencing factors of WFT to conduct research on the delineation standard of pavement WFT. (2) In order to meet the future traffic safety dynamic early warning needs, road factors of different material types, disease conditions and linear conditions should be studied, as well as a comprehensive and accurate real-time water film thickness detection and evaluation method considering meteorological factors of rainfall timing, scale and intensity. (3) The prediction model of WFT should be further studied by the analytical method to clarify the influence of the pavement WFT on the driving safety.

在风暴或降雨过程中,路面上的水厚度会增加,导致车辆轮胎和路面失去接触,并使驾驶员面临直接危险,尤其是在高速行驶时。因此,这是一种相当危险的道路状况,路面水膜厚度(WFT)的真实测量和预测模型对于确定道路摩擦系数和评估降雨对交通安全的影响至关重要。本文对目前路面WFT检测方法的原理和关键性评价进行了综述,以确保其一致性和准确性。针对不同的路面水膜厚度检测要求,给出了方法选择指南。本文还介绍了沥青路面WFT检测和预测模型的最新发展,并从不同的建模思路给出了不同WFT预测模型的计算元素和条件,为未来研究人员选择和优化WFT模型提供了依据。本文还提出了一些见解,作为该主题的进一步研究方向。(1) 本研究可以考虑WFT的影响因素,对路面WFT的划定标准进行研究。(2) 为了满足未来交通安全动态预警需求,应研究不同物质类型、疾病条件和线性条件的道路因素,以及考虑降雨时间、规模和强度等气象因素的全面准确的实时水膜厚度检测和评估方法。(3) 应通过分析方法进一步研究WFT的预测模型,以阐明路面WFT对行车安全的影响。
