The Impact of Visual and Aesthetic Elements on the Organization of the Urban Cityscape

Abstract Urban landscape organization is considered one of the most important tasks undertaken by urban designers. It is a precise process that requires a scientific and systematic approach through several key concepts such as harmony, integration, and sensory and visual organization. This requires attention to planning, design, and architectural aspects, with particular focus on the visual and aesthetic elements of city centers. This can be achieved by carefully considering all elements that contribute to enhancing the visual appearance while simultaneously fulfilling essential community and environmental needs. Examples include the distribution, characteristics, quality, and placement of street furniture elements such as seating benches, lighting poles, telephone kiosks, trees, and others. Accordingly, there is an urgent need to improve the urban environment, particularly in cities of the developing world, where city centers are experiencing significant deterioration. Many of these centers have become unsafe, unclean, and visually distorted due to the spread of posters, images, and graffiti on walls, in addition to congested streets with both vehicular and pedestrian movement, and the uncoordinated mixture of old and modern buildings. This situation is clearly observable through direct field observation while moving through different city streets. The urban landscape of Khartoum is not different from that of many cities in the developing world. It represents a cumulative response to traditional construction heritage in the region, in addition to the impact of policies and plans implemented in the city, which have significantly shaped the current urban landscape. This has resulted in several planning problems, reflected in various forms of visual pollution, most notably the lack of aesthetic elements needed in main streets in general and the city center in particular, which are essential for facilitating citizens’ movement, improving comfort, and enhancing the city’s visual attractiveness. A quick overview of the city center reveals that the existing elements, despite their limited number, lack scientifically planned coordination. This may be due to the absence of appropriate urban planning and design, or the focus of responsible authorities on limited aspects such as road paving, lighting, and tree planting only, or due to weak coordination among institutions responsible for urban planning and design. This is despite the notable efforts made by the Khartoum State Center Development Authority, particularly within the study area. This research aims to study visual and aesthetic elements and their impact on the organization of Khartoum’s urban landscape, with a focus on Africa Street. This is achieved through evaluating the current condition of existing elements and proposing development strategies that enhance the area aesthetically, visually, and functionally, contributing to achieving a visually and aesthetically harmonious composition compatible with the natural environment. The study primarily relied on descriptive and analytical methodologies, in addition to comprehensive field surveys. The findings indicate that achieving a distinctive and coherent urban identity requires conducting visual studies based on visual composition elements at the macro scale of the studied sector, followed by strict adherence to these outputs during the detailed design phase of all urban composition elements. The study also recommends establishing urban design regulations and legislation governing the design and distribution of visual and aesthetic elements, as well as preparing comprehensive master-level designs defining decorative elements, color schemes, and building boundaries for each street and urban sector.
