Many countries over last few decades have worked on complete street planning and designing. As per various researches and organizations, the complete streets are the streets that are context sensitive and designed to accommodate all types of users, considering safety, accessibility and mobility for all types of users. The type of user for every street may vary due to the function and context of the street. Streets are not only the linear linkages but should be treated as 3D spaces. To have a context sensitive street it is equally important that the built mass along the street should be evaluated and designed accordingly. The proposed evaluation methodology will be done at overall level to study the street context, overall quality of services, detailed study for street design elements and measuring urban design qualities for pedestrians through which the study will go one step ahead and evaluated the importance of integrated approach for complete street planning and design. For the evaluation of the streets the selection of study area was on the basis of its context and function. The urban landuses identified are residential, commercial, intuitional and open spaces, which contributes about 85% of the land reservation in master plan. This paper aimed to present the quantitative and qualitative framework evolved to evaluate the street planning and design through identified streets to assess the completeness of the existing streets in Gurgaon. The method of evaluation will help to check the completeness of streets in terms of context, quality of services, street design elements and urban design quality for pedestrians. Through street evaluation the shortfalls can be prioritized and streets can be improved accordingly to become the complete street. The method will help to check the completeness of streets in Gurgaon and other cities with some variations for better cities and better streets.

“…This study demonstrates how to calculate the fractal dimension of street silhouettes. Additionally, Cooper (2005) and Oppong et al (2017) conducted a study on fractal dimension calculations for street edges, demonstrating how to calculate the fractal dimension for street edges and how to relate the obtained numerical values to the character of a place.…”

The aim of this article is to reveal the mathematical dimension behind the complex structure of architectural fabric through a three-dimensional analysis. Given that the architectural character, which has evolved under the influence of various cultures over time, is crucial for urban integrity and sustainability, understanding the mathematical dimension underlying this character is of great importance for new designs and interventions in existing urban fabric. Therefore, streets in the Arabahmet neighbourhood of Lefkoşa Suriçi, which best represents the traditional fabric, were examined using a three-dimensional fractal analysis method. The analyses indicate that, in general, the fractal dimension values of the residential fabric-created streets are above 2.52, demonstrating a high level of character and complexity in these streets. Additionally, the fractal dimension values of these streets are close to each other, supporting the spatial and mass consistency of different streets within the same neighbourhood.

“…Micro-/meso-scale studies have been conducted on the fractal geometry of urban architecture [19,20], and have explored the urban fractal form at various scales, such as neighborhoods and street edges [21,22]. As a community or block can be used as a practical geographical unit to study the compactness of a whole city [23,24], many studies have analyzed aspects such as the physical environment of buildings, natural terrain, and walking systems at the neighborhood scale.…”

Modern expansion and three-dimensional growth are rapidly altering the morphological features of traditional cities. This morphological phenomenon fully reflects the internal organization mode and composition rules of modern cities. This study draws on the research method of three-dimensional fractal, focusing on the situation where there is less research on the fractal form at the block scale, and conducts a fractal research on the three-dimensional form of a city at the meso and micro scales, in order to reveal the fractal characteristics of modern urban density. Based on fractal theory, the urban form of Shenyang, Northeast China, was quantitatively analyzed using the box-counting (Minkowski–Bouligand) method to calculate the two-dimensional (2D) and three-dimensional (3D) box dimensions of urban areas. Next, by analyzing the correlations between morphological indicators and 2D and 3D fractal dimensions, this study proposes cluster features of the correlation between the 3D fractal dimension and floor-area ratio. Then, this study summarizes the fractal characteristics of Shenyang’s urban form, based on the cluster analysis and spatial features of various urban areas within the city. The analysis results show the fractal dimension of Shenyang’s urban form to have characteristic expected values; fractal dimension clusters reflect spatial differences in the forms of different urban areas. The 3D D value of architectural morphology fractal in urban areas of Shenyang is between 2.41 and 2.70. From this, the representative characteristics of Shenyang’s urban form were obtained: first, it has the fractal characteristics of morphological hierarchy and system embeddedness; second, under unified and standardized management, its basic urban form structure displays the fractal characteristics of morphological similarity and system hierarchy; and third, its 3D urban form characteristics include the spatial accumulation of clusters and morphological patches, creating a patchwork of different building heights and densities, with the spatial clustering of density form highly correlated with the fractal dimension. The results of this research will provide reference samples for the morphological identification, design control, and design review of modern cities, and enrich the research results of the application of fractal theory to urban morphology at the meso and micro scales.
