Abstract
When looking at the city of Alexandria, the amount of traffic, pollution, and loss of green spaces may lead one to think that the best solution would be to eliminate all road traffic; however, the issue is more complex. The degrading state of many facilities and streetscape design elements lowers the city’s livability and pushes people away from the waterfront. The Alexandria waterfront has a very strong potential within its rich historical legacy, necessitating rapid action. The city’s development should then start with its strongest qualities. Moreover, with the continuous growth of digital technology, people’s needs for urban spaces have differed. These needs must be specified, and new possibilities and atmospheres should be created to cope with the emerging challenges of the 21st century. In this context, the thesis aims to develop a framework for achieving livability in urban spaces through the placemaking concept by activating the role of streetscape elements. These elements will be augmented by mixed interventions referred to as the “Digital Streetscape” hybrid approach. Through eight sequential chapters, the thesis demonstrates that urban livability can be achieved through the placemaking concept by identifying both subjective and objective attributes and their indicators. Then, it shows how the streetscape design elements (the objective attribute) play a significant role in enhancing the qualities of urban spaces (the subjective attribute) and serve to render people’s environments more livable, safe, sustainable, and attractive. Therefore, to create such a livable space, this study suggests improving the streetscape design elements through the technical attribute that will augment them with a new digital layer of mixed interventions, including smart, eco-oriented, and tactical urbanism. It then proposes the three-dimensional matrix model as a tool for assessing urban livability in the 21st century. The thesis investigates some relevant examples from different cities around the world that have successfully transformed their dead urban spaces into more livable ones, concluding that it is not necessary to implement all three types of interventions in urban spaces, but rather according to their scale, role, and location. Thereby, the thesis applies the findings and results ia Corniche and analyzes them using both qualitative and quantitative methods to highlight potentials and identify problems, considering both residents and urban space users. Finally, it recommends effective strategies to decrease the problems and enhance the quality of waterfront urban promenades in general, and Alexandria’s waterfront urban spaces in particular. It should be noted that the application of the suggested framework is not totally thematic; it depends on the planner who is applying it, and so results may vary from planner to planner. Furthermore, some careful studies must be made to analyze the urban environment before implementing any kind of intervention. However, this attempt is conceived as a pilot study that remains open and can be amended and readjusted with more/less streetscape elements on one side, urban livability principles on the other, and streetscape interventions on the third.
