Walkability is an essential urban quality which required for every sustainable community. Since a few decades, attention goes to walkability as a key to achieving health, social and economic sustainability. Since the beginning of the twenty-first century, Scientists have documented many scientific contributions. Each publication focuses on one or multi- aspect of the walkable built environment. The whole picture of the development process of walkability is still complicated and ambiguous. This paper aims to explore the development process by using a problem-solving approach. Problem-solving approach requires four steps which are problem definition, cause and significant factor identification, and determine the internal and external factors, and structure solutions to the problem. First, Muscat Governorate in the Sultanate of Oman was a case study. Secondly, group panel discussion has been conducted and monitored by the Nominal Group Technique. The panel was video tapped and converted into text. A text mining software was used to quantify and analyze the discussion objectively. Finally, the outcome was analyzed to define the required process to enhance walkability in Muscat- Oman.
In conclusion, the paper presents a case study for an objective exploratory methodology by using text mining tool. It was found efficient to bridge the gap between absent practice and to address the future required process. The study is limited to address answers for a specific case study, but the methodology is sufficiently applied for other case studies for any problem- solving approach.
