In the developed world, there are numerous guidelines for streetscape design; i.e. rigid pre-set menus of cross-sections for streets with pre-defined functional classifications and technical specifications. The guides may not only vary from country to country, but also from city to city, depending on variable local conditions and demands. Thus, the available guidelines in the developed urban areas may not be a proper tool for the streetscape design in some old cities in developing countries that are densely-populated and their streets are highly congested. In this paper, a successive flexible process is developed that can be applied as a tool for the design or reclaiming of a streetscape in an existing built area. It is established on the basis of the formulation of different street design alternatives, each of which identifies the right-of-way and includes the needed width of the different design elements. The selection of the preferred alternative is provided through the trade-offs among the scenarios regarding the users perspectives and the community and environmental objectives as well. The proposed process is then applied to develop the streetscape of a street segment in Alexandria, as a case study. The application confirms its practicality and capability for improving the urban quality in terms of mobility, livability, and safety.
