Taxi services are among the most frequently used passenger transport services in many cities in the world. Taxis are an integral part of a city’s image. In a recent IRU/EU report taxis are considered as part of the collective public transport chain. In this context taxis role is a complementary mobility option to public transport rather than a competitive one. In the growing city of Dubai taxis are utilized by many local and foreign residences as well as by tourists and visitors. The annual number of taxi trips reached 104 million trips in 2016, while the fleet is growing currently at 9613 and is expected to reach around 12,765 by 2020. Riding a taxi in Dubai is known to be pleasant, comfortable, convenient and relatively affordable experience. The Roads and Transport Authority (RTA) is the Dubai government authority responsible for the planning and governance of the taxi sector in Dubai. The RTA through its agency namely the Public Transport Agency (PTA) exercises such roles. This research is meant to provide a system analysis and structured assessment of the taxi sector in Dubai with the objective of identifying strengths and gaps as well as reviewing the literature and conducting stakeholder consultation hence culminating on developing a comprehensive taxi strategy in Dubai. Such strategy would be targeted to achieve customer satisfaction leading eventually to customer happiness. All in all this is expected to provide an added value and benefit to the business planning for PTA as well as for the overall strategic and futuristic planning by RTA.展开更多

The first is referred to as the road safety pyramid representing children road safety components and levels including root, at accident and post accident levels and factors. The second, referred to as the children road safety assessment pyramid, includes 3 cornerstones that are required to represent a detailed methodological children road safety diagnostics. These 3 cornerstones include children safety culture, safety indicators and accident data analysis. The third pyramid, referred to as the children road safety indicators, shows the levels and types of indicators that when computed can be used for in depth analysis and historical comparison of children road safety. The core of the paper is the development of a conceptual model of factors affecting the road behavior of children including traffic exposure and experience, cognitive skills and abilities, perceptual skills, knowledge and attitude. Towards this end, the paper presents the fourth pyramid, referred to as the children road safety behavior pyramid. This includes a 7-level hierarchal structure starting from exposure leading to experience and then skills/abilities, to knowledge to perception to attitudes and eventually culminating into children road safety behavior. The paper concludes by developing a generic integrated children road safety package of policies, measures, initiatives. The package is composed of 18 fields of action. In pursuing such integrated safety package this research also enhanced the classical 3Es concept (Engineering—Education—Enforcement) and introduced instead the 14Es honeycomb structure including (Engineer-ing—Education—Environment—Enforcement—Egalitarianism—Exposure—Ethics—Emergency—Ergonomics—Encouragement—Empowerment—Enabling—Economics—Evaluation). All in all this is meant to act as a generic benchmark guide/checklist for countries in compiling and tailoring children road safety programmes.展开更多

This indicates very low agricultural capacities. Otherwise agricultural activities are concentrated in a narrow fringe of the Northern part of the country where the dominant climate is semi-arid with very irregular rainfalls. A majority of farms produces its main part of income from cereal crops--livestock association system. However, the diversity of the climate and the physical environment, on one hand, and the agricultural policies on the other hand, induce major transformations in this system. Transformations are also the result of a significant demographic growth in rural area. In this context, significant issues appear in term of resource＇s uses and systems＇ sustainability. To shed light in the actual situation, this study, based on a survey of 90 owners, shows that： the intensification can constitute a threat on the pastoral resources; the weakness of the farms encourages the generalization of practices characterised by a weak feed autonomy and a bad management of stock fodders; the animal interspecific integration and partial intensification are positive if they follow models which ensure autonomy, performance and optimal pastoral resource management.展开更多

The TSMC is meant to conceptualise the main strategic generic components characterising the maturity of transit systems. The TSMS is an S shaped scaling system for measuring maturity of transit system components. The TSMI presents an innovative index meant to assess the overall level of maturity of a city transit system. Such framework is envisaged to be used to determine and compare the overall maturity levels of transit systems in cities of the world as well as to act as a basis to identify strengths & gaps that need to be addressed/completed. Furthermore, it can also act as an ingredient in shaping and developing future road maps for transit system in cities across the world. The research concludes by demonstrating the applicability of TSMC, TSMS, and TSMI in conducting an initial assessment of the Transit System Maturity for the fast growing city of Dubai.展开更多
