Abstracthis paper presents the findings of a study, implemented in Abu Dhabi, which aimed to examine the direct effects of the use of traffic safety technologies on the mitigation of risks associated with traffic accidents. The study adopted the use of a questionnaire-based survey with traffic safety experts in Abu Dhabi Emirate. The views of more than a hundred respondents were collected on areas such as the status of existing traffic safety technologies in Abu Dhabi’s highway network, the impact of traffic safety technologies on enforcement, existing highway design practices, effects of driver education on safety and the impact of safety technologies on the efficiency of emergency responses. Factor analysis and Freidman tests were employed for the interrogation of the data in order to extract findings from the views of different experts on the aforementioned areas. The analysis showed that the deployment of traffic safety technologies has a positive impact on the efficiency of enforcement practices and improvements on traffic safety, and on enhancing operators’ efficiency and capability in taking appropriate and prompt action in situations calling for emergency responses. Moreover, speed cameras and VMS deployment are highly favoured in addressing engineering design shortfalls. Also, training and awareness enhance the efficiency and effectiveness of traffic safety technologies.

A FRAMEWORK FOR THE DEPLOYMENT OF TRAFFIC SAFETY TECHNOLOGIES IN ABU DHABI HIGHWAYSAl Junaibi, Musallem (2016-05)There has been a good effort made in Abu Dhabi for the last couple of years between government stakeholders to develop a road safety strategy, define rules and responsibilities, and gain a fully coordinated and integrated framework to deal with road safety. According to my point of view, the challenges that might be seen as a problem for the future development of Abu Dhabi can be the management and the usage of traffic safety technologies to reduce serious road traffic accidents. This study focused on the relationship between the use of traffic safety technologies and serious road traffic accidents on Abu Dhabi Highways. The motivation for this research is to implement correctly the traffic safety technologies in Abu Dhabi highways as a part of the need to adopt plans, programmes, and preventive measures to reduce or prevent the occurrence of traffic accidents in order to ensure the safety of individuals and property, in addition to preserving the security of the state and its human and economic components. The overall approach to this study is a mixed methodology, which combines quantitative and qualitative methods. A questionnaire is one method used in this regard, and is designed to be quantitative. In the quantitative method, comparing statistics of fatalities and injuries before and after installation of the speed cameras is used. As a result of this study and by making the connectivity between reviewing the results and findings of the literature review, identifying the questionnaire results, and exploring the before and after statistics led to findings which were used to develop a decision support framework that can be used to advise the regional safety strategy to be sustainable. The design framework was also validated through Abu Dhabi highways by a panel of experts, which was carried out using the focus group method, which was qualitative in nature. It is recommended from this research to invest much in traffic safety technologies, focus more on driver support systems and rapid response systems, improve driver behaviour as a priority in Abu Dhabi highways using traffic safety technologies, and integrate the compatibility of all of the above through an integrated system and specific performance indicators that are measured and followed up on an ongoing basis, and supported by geographic information systems (GIS).
Development of a model for health and safety management in Saudi Arabian oil and gas construction projectsOduoza, Chike; Alamri, Reem (University of Wolverhampton, 2019-09)Health and safety is regarded as the foundation of the construction and production process in the oil and gas sector. However, in the Saudi Arabian oil and gas construction industry, this very foundation is threatened by the proliferation of work-related hazards that leave workers permanently or temporarily incapacitated. In comparison with other industrial sectors, workers on oil and gas construction sites are at greater risk of facing a variety of health and safety related risks, and that is the reason why it is essential to prevent the increasing level of accidents on these sites. Although, efforts were made to minimize exposure to such risks in the Saudi oil and gas sector, there is still a need for radical changes in the way the sector approaches health and safety issues. In this regard, this study examines the effectiveness of existing health and safety measures followed in Saudi Arabia, while looking at critical areas that require immediate attention as well as new measures that can be implemented to improve in those areas. To achieve this, both quantitative and qualitative research methods were used. For the quantitative research, questionnaires were designed and distributed to 300 respondents who work in construction companies in Saudi Arabia. For the purposes of obtaining answers from relevant respondents, construction companies who have experience from working on oil and gas construction projects were targeted. A total of 200 questionnaires were completed and returned. The quantitative data was analysed by descriptive and inferential statistics using Statistical Package for the Social Sciences (SPSS) software. For the qualitative data, semi-structured interviews were conducted with nine professionals purposely selected due to their knowledge, years of experience and familiarity with health and safety policies and standards on oil and gas construction sites. The analysis of the qualitative data was achieved using qualitative data analysis software QSR Nvivo. During qualitative data analysis, thematic analysis was adopted to build themes from the data which formed the basis for the presentation of the results from this research. Findings from the research suggest that all participants are of the view that oil and gas construction projects have more health and safety issues compared to average construction projects. It was found that the nature of the oil and gas industry coupled with the risky nature of construction activities presented higher risk which led to increased health and safety issues when constructing in the sector. The results also indicated that there was a low level of involvement from the construction site teams and workers in the development of health and safety policies for oil and gas construction projects. It was also identified that there was very poor adherence to health and safety standards and regulations on oil and gas construction sites due to little or no understanding of requirements andprocedures, as well as the advantages of adhering to such. Poor enforcement of government legislation was also identified to be another major cause for the poor health and safety performance of oil and gas construction projects. Based on the aforementioned results and the findings obtained from literature, a framework was developed to ensure that health and safety was properly institutionalised throughout the processes undertaken by construction firms during project management. The framework recommends both corporate level and project level policies that could facilitate the adoption and implementation of health and safety guidelines on construction projects in the oil and gas sector. An implementation guide was equally presented alongside the framework in view that it would ensure that users covered all the necessary areas in terms of health and safety and that all parties were involved in the process. The research concludes that construction projects in the oil and gas sector are riskier and demand approaches and strategies specific to the type of projects undertaken. The study finally recommends that further research should be undertaken to propose alternative models and national level legislative framework for enhanced health and safety guarantee especially in the Saudi oil and gas construction industry.
Traffic event detection framework using social mediaSalas, A; Georgakis, P; Nwagboso, C; Ammari, A; Petalas, I (IEEE, 2017-09-18)© 2017 IEEE. Traffic incidents are one of the leading causes of non-recurrent traffic congestions. By detecting these incidents on time, traffic management agencies can activate strategies to ease congestion and travelers can plan their trip by taking into consideration these factors. In recent years, there has been an increasing interest in Twitter because of the real-time nature of its data. Twitter has been used as a way of predicting revenues, accidents, natural disasters, and traffic. This paper proposes a framework for the real-time detection of traffic events using Twitter data. The methodology consists of a text classification algorithm to identify traffic related tweets. These traffic messages are then geolocated and further classified into positive, negative, or neutral class using sentiment analysis. In addition, stress and relaxation strength detection is performed, with the purpose of further analyzing user emotions within the tweet. Future work will be carried out to implement the proposed framework in the West Midlands area, United Kingdom.
