Urban infrastructure can be depicted as critical facilities for providing urban public services and supporting urban socioeconomic activities. Economic growth, especially the provision of sustainable mobility in urban areas, is found to be reliant on the availability of effective transport infrastructure. Urban transport assets, mainly road and railway infrastructure, have notable influence on the safety and convenient connectivity of economies, communities, and ecosystems. While the vitality of urban transport infrastructure provision is well recognized, its practice is marred by several challenges. Addressing those challenges may require interventions throughout the life cycle of the facilities, including planning, design, construction, commissioning, operation, and demolition phases. This study, however, focuses on formulating key guiding principles and methods for effective design of transport infrastructure in urban areas of Ethiopia. The provision of transport infrastructure requires an effective design methodology throughout the lifecycle of the built element. The study involved a thorough analysis of the literature review to identify the current delivery approaches, and a questionnaire survey with a sample size of 204 (N = 204) was then utilized to determine, based on the opinions of experts, the most efficient methods of delivering transportation infrastructure. A descriptive and factor analysis were utilized to forward the demographic data of the research findings and to identify the key components of transport infrastructure delivery through design, respectively. The study found that the principal components that directly impact the design and delivery process of urban transport are design context, design necessities, institutional competency, and professional competency. It can be concluded that consideration of the principal components at the time of design assignment would facilitate the design products' effectiveness.
城市基础设施可被描述为提供城市公共服务和支持城市社会经济活动的关键设施。人们发现，经济增长，尤其是城市地区可持续交通的提供，依赖于有效的交通基础设施。城市交通资产，主要是道路和铁路基础设施，对经济、社区和生态系统的安全及便捷连通性有着显著影响。虽然城市交通基础设施建设的重要性已得到充分认可，但其实施却面临若干挑战。应对这些挑战可能需要在设施的整个生命周期内进行干预，包括规划、设计、建设、调试、运营和拆除阶段。然而，本研究的重点是为埃塞俄比亚城市地区交通基础设施的有效设计制定关键指导原则和方法。交通基础设施的建设需要在建筑元素的整个生命周期内采用有效的设计方法。该研究对文献综述进行了深入分析，以确定当前的交付方式，然后进行了一项样本量为204（N = 204）的问卷调查，以便根据专家意见确定交付交通基础设施最有效的方法。分别采用描述性分析和因素分析来呈现研究结果的人口统计数据，并通过设计确定交通基础设施交付的关键组成部分。研究发现，直接影响城市交通设计和交付过程的主要组成部分是设计背景、设计必要性、机构能力和专业能力。可以得出结论，在设计任务时考虑这些主要组成部分将有助于提高设计产品的有效性。
