It is known that street elements influence the vernacularity and livability of urban spaces, the quality of life and the vitality of society everywhere in the world. Thus, there has been an urgent need to examine the quality and suitability of streets, specifically the commercial streets facing rapid developments and urbanization. Indeed, it is more so in Jordan. In this context, this research investigates the effect of physical characteristics of elements of livable streets where people can enjoy life and act freely. In other words, produce vernacularity.The research employs mixed methods; qualitative and quantitative methods within a case study. Data collection techniques include a desk study, direct observation and a questionnaire survey.The findings indicate that applying and paying attention to the characteristics such as color, shape, size, placement of the signs, colors of light, and light in general can achieve livable streets that promote vernacularity. The study suggests a framework to regulate the priorities of principles and the variables of streetscape elements, to help the decision-makers in municipalities and urban planners to bring about livable streets: in other words, promote vernacularity in cities.
