In recent years, conflicts between crossing pedestrians and right-turning vehicles have become more severe at intersections in China, where right-turning vehicles are usually not controlled by traffic signals. This study proposes a quantitative method for evaluating the conflict risk between pedestrians and right-turning vehicles at intersections based on micro-level behavioral data obtained from video detection. A typical intersection in Shanghai was selected as the study site. In total, 670 min of video were recorded during the peak hours from 7:30 a.m. to 9:30 p.m on one day. After processing the video information, vehicle and pedestrian tracking data were obtained, including the velocity, acceleration, deceleration, time, and location coordinates. Based on these data, several conflict indicators were proposed and these indicators were extracted automatically using MATLAB to identify pedestrian–right-turning vehicle conflicts and to determine the severity of the conflicts identified. This process identified 93 examples of such conflicts. The conflict risks were quantitatively classified using the K-means fuzzy clustering method and all of the conflicts were assigned to five grades. The characteristics of the conflict distribution and the severity of different types of conflict were also analyzed, which showed that conflicts on different areas on the crosswalk differed in their severity. Based on the conclusions, practical traffic management and control measures are proposed to reduce the risk on pedestrian crossings.

Dengue fever is a painful mosquito-borne infection caused by different types of virus in various localities of the world. There is no particular medicine or vaccine to treat person suffering from dengue fever. Dengue viruses are transmitted by the bite of female Aedes (Ae) mosquitoes. Dengue fever viruses are mainly transmitted by Aedes which can be active in tropical or subtropical climates. Aedes Aegypti is the key step to avoid infection transmission to save millions of people in all over the world. This paper provides a standard guideline in the planning of dengue prevention and control measures. At the same time gives the priorities including clinical management and hospitalized dengue patients have to address essentially.

The introduction of new market-based instruments (MBIs), such as eco-taxes and tradable permits, has prompted major changes in the implementation of environmental policy in the European Union. However, rather than wholeheartedly embracing the logic of environmental economics, governments have preferred to introduce MBIs alongside more traditional command-and-control measures, ostensibly to guarantee that policy objectives are met. Where such regimes of governance have underperformed, this raises the question as to whether difficulties are caused principally by flawed theory or regulatory failure, namely errors in policy design that distort MBIs from intended changes in market behaviour. Analysis of a tradable-permit scheme in Packaging Recovery Notes introduced to implement the UK Packaging Regulations reveals that, in this case, the difficulties experienced with an MBI were, in fact, traceable to regulatory failure. Different types of regulatory failure are identified and discussed.

This article addresses phenomenon of emotional burnout. Analyzing the origin of this term, the main approaches to analysis of emotional burnout specificity are described including different symptoms and phases. The problem of value of emotional burnout syndrome of pedagogical workers of state and commercial preschool educational organizations of different types is determined. The results of the research on identification of emotional burnout of pedagogical workers of state and commercial preschool educational organizations specificity, are described. The research is implemented on the sample of survey respondents up to 50 persons using such methods as a questionnaire “Professional (emotional) burnout” (MBI) (K. Maslatch and S. Jackson in adaptation of N.E. Vodopyanova); “Diagnostics of personal emotional burnout” (V.V. Boyko). The conclusions according the existence of distinctions in stages and symptoms of emotional burnout syndrome of pedagogical workers of preschool educational organizations of different types and the importance of the research specificity in appearance of this phenomenon are formulated in order to find the most appropriate preventive and control measures in the sphere of emotional burnout.

A large international airport is a microcosm of the entire aviation sector, hosting hundreds of different types of aviation and non-aviation stakeholders: aircraft, passengers, airlines, travel agencies, air traffic management and control, retails shops, runway systems, building management, ground transportation, and much more. Their associated information technology and cyber physical systems—along with an exponentially resultant number of interconnections—present a massive cybersecurity challenge. Unlike the physical security challenge, which was treated in earnest throughout the last decades, cyber-attacks on airports keep coming, but most airport lack essential means to confront such cyber-attacks. These missing means are not technical tools, but rather holistic regulatory directives, technical and process standards, guides, and best practices for airports cybersecurity—even airport cybersecurity concepts and basic definitions are missing in certain cases. Unsettled Topics Concerning Airport Cybersecurity Standards and Regulation offers a deeper analysis of these issues and their causes, focusing on the unique characteristics of airports in general, specific cybersecurity challenges, missing definitions, and conceptual infrastructure for the standardization and regulation of airports cybersecurity. This last item includes the gaps and challenges in the existing guides, best-practices, standards, and regulation pertaining to airport cybersecurity. Finally, practical solution-seeking processes are proposed, as well as some specific potential frameworks and solutions.

The vehicle sensor information and road side sensor information will be collaborative used in traffic management and control. In order to improve the comprehensiveness and economy of the traffic and road conditions’ information collection, we focus on the intelligent roadside system in this paper. Firstly, we analyse the functions of the intelligent roadside system. Through the analysis of the detection range, detection accuracy, price and applicable conditions of similar sensor, we delineate the selection range of the intelligent roadside sensor. Then we determine the layout scheme of the testing equipment sensors for different functions according to different types of network structure. Finally, we apply similarity analysis to optimize the configuration density to reduce system cost by selecting the sensor layout-intensive sections.

This paper reported an evaluation study of CIVITAS II measures at 12 European cities from the perspective of environmental impacts. Subsets of comparable traffic management and control measures have been created and their environmental impacts evaluated using the indicators of fuel savings and emission reductions. The environmental impacts of these traffic management measures were focused in this paper, and it is found that some of the traffic management measures have positive effect on the environment.
