Abstract The logistics performance has a crucial role in the industrial and economic development of countries. This study aims to underline implications for policy makers in improving the logistics performance of countries in terms of Industry 4.0. For this purpose, the effect of digitalisation on logistics performance is analysed by using correlation and multiple regression analysis. The empirical study builds upon dimensions and indicators of the Digital Economy and Society Index (DESI) and Logistics Performance Index (LPI) of the World Bank. The results indicate that governmental policies should target to deliver sound framework conditions for the generation of human capital (here: ICT specialists), sustainable usage of internet services (e.g. professional social networks, online sales, etc.), integration of digital technologies (e.g. Big Data, Cloud computing, etc.), as well as digital connectivity (here: fixed broadband and 4G coverage) in order facilitate improvement of logistics performance.
物流绩效在各国的工业和经济发展中起着至关重要的作用。本研究旨在强调政策制定者在工业4.0条件下改善各国物流绩效的影响。为此,通过使用相关和多元回归分析来分析数字化对物流绩效的影响。实证研究以世界银行的数字经济与社会指数(DESI)和物流绩效指数(LPI)的维度和指标为基础。结果表明,政府政策的目标应该是为人力资本的产生(这里:ICT专家)、互联网服务的可持续使用(例如专业社交网络、在线销售等)、数字技术的整合(例如大数据、云计算等)以及数字连接(这里:固定宽带和4G覆盖)提供良好的框架条件,以促进物流绩效的改善。

Abstract Recent years have witnessed a colossal increase of vehicles on the roads; unfortunately, the infrastructure of roads and traffic systems has not kept pace with this growth, resulting in inefficient traffic management. Owing to this imbalance, traffic jams on roads, congestions, and pollution have shown a marked increase. The management of growing traffic is a major issue across the world. Intelligent Transportation Systems (ITS) have a great potential in offering solutions to such issues by using novel technologies. In this review, the ITS-based solutions for traffic management and control have been categorized as traffic data collection solutions, traffic management solutions, congestion avoidance solutions, and travel time prediction solutions. The solutions have been presented along with their underlying technologies, advantages, and drawbacks. First, important solutions for collecting traffic-related data and road conditions are discussed. Next, ITS solutions for the effective management of traffic are presented. Third, key strategies based on machine learning and computational intelligence for avoiding congestion are outlined. Fourth, important solutions for accurately predicting travel time are presented. Finally, avenues for future work in these areas are discussed.

Abstract Increasing requirements in the field of security, in particular in the transport sector, the rescue work, the inviolability of private property and others urged to research work in the field of radar monitoring people, vehicles or other objects in the environment that not allow make so using the most popular and available technology for production and analysis of video images. These conditions of poor visibility, or even lack thereof, are darkness, bad weather, smoke, dust, wall (roof) buildings and the vehicle body. Existing instruments and special equipment occupy a certain niche in this area, mainly for counter-terrorism operations. However, such equipment is not readily available and extremely high price. In the paper presented research is development of the group’s existing radar technology in the field of location through opaque obstacles.
摘要安全领域的需求日益增加,特别是在交通部门、救援工作、私有财产的不可侵犯性等方面的要求促使研究工作在雷达监测人员、车辆或其他不允许的环境中的物体,使之利用目前最流行和可用的技术进行视频图像的制作和分析。这些能见度差,甚至缺乏能见度的条件是黑暗,恶劣天气,烟雾,灰尘,墙壁(屋顶)建筑物和车身。现有仪器和专用设备在这一领域占有一定的地位,主要用于反恐行动。然而,这种设备并不容易获得,而且价格极高。本文研究的是该集团现有雷达技术在不透明障碍物定位领域的发展。

Abstract Several European road operators and authorities joined the C-Roads Platform with the aim of harmonising the deployment activities of cooperative intelligent transport systems (C-ITS). C-ITS research is preliminary to future automated-driving vehicles. The current conventional highways were designed on traditional criteria and models specifically developed for traffic flows of manually guided vehicles. Thus, this article describes some new criteria for designing and monitoring road infrastructures on the basis of performance features of autonomous (or self-driving) vehicles. The new criteria have been adopted to perform an accurate conformity control of the A22 Brenner motorway, included in the C-Roads Platform, and also to ascertain whether in future it may be travelled by automated vehicles in safety conditions. Always in accordance with the technical and scientific insights required by the C-Roads Platform, a traffic model has been implemented to estimate how the A22 capacity increases compared to current values, by taking various percentages of automated or manual vehicles into consideration. The results given by theoretical models indicate that the highway will be able to be travelled by automated vehicles in safety conditions. On the other hand, the lane capacity is due to increase up to 2.5 times more than the current capacities, experimentally determined through traffic data collected from 4 highway sections by means of Drake’s flow model.
几个欧洲道路运营商和当局加入了C-Roads平台,目的是协调合作智能交通系统(C-ITS)的部署活动。C-ITS的研究是未来自动驾驶汽车的初步研究。目前的传统公路是根据传统的标准和专门针对人工引导车辆交通流开发的模型设计的。因此,本文描述了基于自动驾驶(或自动驾驶)车辆的性能特征设计和监控道路基础设施的一些新标准。采用新标准是为了对包括在C-Roads平台中的A22 Brenner高速公路进行精确的一致性控制,并确定将来是否可以由自动驾驶车辆在安全条件下行驶。始终按照C-Roads平台所需的技术和科学见解,我们实施了一个交通模型,通过考虑不同比例的自动或手动车辆,来估计A22通行能力与当前值相比的增长情况。理论模型的结果表明,在安全条件下,自动驾驶汽车可以在高速公路上行驶。另一方面,车道容量将增加到目前容量的2.5倍,这是通过使用Drake流量模型从4个高速公路路段收集的交通数据进行实验确定的。

Abstract A sustainable transportation system is possible only through an efficient evaluation of transportation network performance. The efficiency of the transport network structure is analyzed in terms of its connectivity, accessibility, network development, and spatial pattern. This study primarily aims to propose a methodology for modeling the accessibility based on the structural parameters of the urban road network. Accessibility depends on the arrangement of the urban road network structure. The influence of the structural parameters on the accessibility is modeled using Multiple Linear Regression (MLR) analysis. The study attempts to introduce two methods of Artificial Intelligence (AI) namely Artificial Neural Networks (ANN) and Adaptive network-based neuro-fuzzy inference system (ANFIS) in modeling the urban road network accessibility. The study also focuses on comparing the results obtained from MLR, ANN and ANFIS modeling techniques in predicting the accessibility. The results of the study present that the structural parameters of the road network have a considerable impact on accessibility. ANFIS method has shown the best performance in modeling the road network accessibility with a MAPE value of 0.287%. The present study adopted Geographical Information Systems (GIS) to quantify, extract and analyze different features of the urban transportation network structure. The combination of GIS, ANN, and ANFIS help in improved decision-making. The results of the study may be used by transportation planning authorities to implement better planning practices in order to improve accessibility.
只有通过对交通网络性能的有效评估,才有可能建立可持续的交通系统。从连通性、可达性、网络发展和空间格局等方面分析了交通网络结构的效率。本研究旨在提出一种基于城市道路网络结构参数的可达性建模方法。可达性取决于城市道路网络结构的布置。利用多元线性回归(MLR)分析了结构参数对可达性的影响。本研究尝试引入人工智能(AI)的两种方法,即人工神经网络(ANN)和基于自适应网络的神经模糊推理系统(ANFIS)进行城市道路网络可达性建模。研究还比较了MLR、ANN和ANFIS建模技术在可达性预测方面的结果。研究结果表明,路网结构参数对可达性有较大影响。ANFIS方法对路网可达性的建模效果最好,其MAPE值为0.287%。本研究采用地理信息系统(GIS)对城市交通网络结构的不同特征进行量化、提取和分析。GIS、ANN和ANFIS的结合有助于改进决策。研究结果可用于交通规划当局实施更好的规划实践,以改善可达性。

Abstract The ever-increasing use of private vehicles makes Advanced Driver Assistance Systems (ADAS) more necessary as they improve users’ convenience, safety and travel time. Although these systems offer significant advantages, they call into question the traditional role of users, making the psychology of drivers towards these technologies a necessary factor for their adoption. The purpose of this paper is to investigate the effects of psychological factors on the use of one of the most widely used ADAS, the Global Navigation Satellite Systems (GNSS). Towards this direction, a literature review was conducted to identify the factors that influence drivers’ behavior and the psychology of drivers towards new technologies. Furthermore, a questionnaire survey was organized in Greece, based on the Theory of Planned Behavior, including additional variables, which were identified in the literature, such as technophilia, trust in technology and endorsement. From the data collected, models predicting the behavior of drivers were developed through structural equation modelling, concerning the use of navigation systems in both urban and interurban networks. The findings of the research reveal that the intention to use a navigation system is determined by various factors such as behavioral beliefs about its usage, normative beliefs and technophilia. The actual use of a navigation system depends to some extent on this intention.
随着私家车使用量的不断增加,高级驾驶辅助系统(ADAS)的使用变得更加必要,因为它可以提高用户的便利性、安全性和出行时间。尽管这些系统提供了显著的优势,但它们对用户的传统角色提出了质疑,使得对这些技术的驱动心理成为采用这些技术的必要因素。本文的目的是研究心理因素对使用最广泛的ADAS之一全球导航卫星系统(GNSS)的影响。针对这一方向,本文进行了文献综述,以确定影响驾驶员行为的因素和驾驶员对新技术的心理。此外,根据计划行为理论,在希腊组织了一项问卷调查,其中包括文献中确定的其他变量,如技术癖、对技术的信任和认可。根据收集到的数据,通过结构方程建模开发了预测驾驶员行为的模型,涉及城市和城际网络中导航系统的使用。研究结果表明,使用导航系统的意图是由多种因素决定的,如对其使用的行为信念、规范信念和技术癖。导航系统的实际使用在某种程度上取决于这一意图。

Sustainable Maritime Fleet Management in the Context of Global Sulphur Cap 2020 2020年全球限硫令背景下的可持续海运船队管理

Abstract Since the implementation of Emission Control Areas (ECA) in 2015, investment decisions related to abatement technologies represent a crucial task in the maritime industry. Currently, the focus in the maritime sector is on Sulphur reductions due to SECA regulations and the legislative of Global Sulphur Cap that started in 2020. A special challenge appears in maritime fleet management where sets of ships have to be considered, representing portfolios of assets that have to be equipped with a variety of different options of abatement technologies. Modern portfolio theory has been applied to various economic decisions to achieve an optimal allocation of resources among different investment opportunities. The research investigates and discusses the application of the Markowitz´ optimization in the context of SECA regulations for maritime fleets. The optimal investment portfolios are taking into account the three most important compliance options based on the use of low Sulphur fuel, the use of LNG fuel and the use of HFO with a scrubber. The theoretical results are empirically validated by a case of a shipping line operating 10 vessels.
自2015年实施排放控制区(ECA)以来,与减排技术相关的投资决策是海运业的一项关键任务。目前,由于SECA法规和2020年开始的全球硫排放上限立法,海事部门的重点是硫减排。在海事船队管理中出现了一个特殊的挑战,必须考虑到船舶组,代表资产组合,必须配备各种不同的减排技术选择。现代投资组合理论已被应用于各种经济决策中,以实现资源在不同投资机会中的最优配置。本研究调查并讨论了马科维茨优化在海上船队SECA法规背景下的应用。最佳投资组合考虑了三种最重要的合规选择,即使用低硫燃料、使用液化天然气燃料和使用带洗涤器的重油。以某航运公司10艘船舶为例,对理论结果进行了实证验证。

Abstract The operating condition of bus transit system has not been efficient in most cities of Iran, and many management methods such as regular bus scheduling, assigning exclusive bus lanes, etc., which are necessary for increasing the efficiency of this system, were not regarded enough. Thus, achieving a method for locating the bus stops and optimizing the number of such stops based on a non-homogeneous spatial and temporal distribution of passengers as well as the local traffic patterns are important to be investigated. As such, the present study aims to investigate the modeling of a bus transit system corridor according to the non-homogeneous spatial and temporal distribution of passengers throughout the route aiming at optimization of the number of attracted passengers to the bus. For this purpose, the 8-km route from Vali-e-asr roundabout to Gas roundabout in the city of Rasht in the north of Iran is selected for modeling. Hammersley sampling method, as well as two heuristic optimization techniques, including a Genetic Algorithm (GA) and Particle Swarm Optimization (PSO) algorithm, are used for generating a non-uniform population and solving the optimization model. Therefore, the results of this analysis are compared to the optimization results by using the probabilistic analysis without considering the reference uncertainty. Finally, the PSO is selected as the superior algorithm for modeling and locating the bus stops due to its results in less travel time, and the validity of robust optimization model is shown due to its higher accuracy and adaptation to the real-world environment. Overall, although the optimization results based on indeterminate analysis in comparison to determinate analysis brought about more average travel time, more population sets were covered by the new introduced stops during 18 active hours of the bus transit system.
伊朗大部分城市公交系统的运行状况并不高效,提高公交系统运行效率所必需的常规公交调度、公交专用道等管理方法没有得到足够重视。因此,基于非均匀的乘客时空分布以及当地交通模式,实现公交站点的定位和优化站点数量的方法是重要的研究课题。因此,本研究旨在根据乘客在整个路线上的非均匀时空分布,研究公交系统走廊的建模,以优化公交吸引的乘客数量。为此,选择伊朗北部拉什特市从Vali-e-asr环岛到Gas环岛的8公里路线进行建模。采用Hammersley抽样法和遗传算法(GA)和粒子群算法(PSO)两种启发式优化技术生成非均匀种群并求解优化模型。因此,在不考虑参考不确定性的情况下,将本分析结果与采用概率分析的优化结果进行比较。最后,选择粒子群算法作为公交车站建模和定位的优越算法,因为它的运行时间更短,并且由于它具有更高的精度和对现实环境的适应性,证明了鲁棒优化模型的有效性。总体而言,尽管基于不确定分析的优化结果比基于确定分析的优化结果带来了更多的平均出行时间,但在公交系统的18个活跃小时内,新引入的站点覆盖了更多的人口集。

Abstract Using a qualitative instrumental case study research design, this study examines the strategies and carbon reduction measures implemented by Sydney Airport to achieve their goal of being a carbon neutral airport by 2025. The study period was from 2013 to 2019. The qualitative data was analyzed using document analysis. Sydney Airport has implemented a wide range of carbon reduction measures that underpin its strategy to become a carbon neutral airport. Sydney Airport’s annual emissions intensity per passenger declined in each year examined in study. Sydney Airport has participated in the Airports Council International Airport Carbon Accreditation Program since 2014 and currently holds Accreditation Level 3: Optimization. Sydney Airport’s goal is to be awarded Accreditation Level 3+: Carbon Neutrality by 2025. Sydney Airport has a carbon offsets agreement in place with a not-for-profit organization.
