Management and Enhancement of Livable Urban Streetscape through the Development of the 3D Spatial Multimedia System

Abstract

Maintaining the continuity of a valuable and livable visual experience is very important for the quality of urban streetscape planning and design. One of the impacts of the rapid development of urban streetscape is unsatisfying pedestrian space for spatial and visual comfort. In line with establishing good governance, it is necessary to evaluate the quality of urban visuals by involving community participation through online participation. The case study on the five provincial streets In Malang, Indonesia, has become a strategic route for the uncontrolled rapid growth of commercial districts alongside these streetscapes. This study promoted spatial multimedia development as a decision support system in the planning process as one of the recent developments in design planning activity by developing a multimedia 3D spatial system based on public preferences in the local community. A combination of three sequential stages was conducted, starting with investigating public preferences that produced spatial and visual comfort assessment through the Semantic Differential method and regression model analysis, followed by the 3D streetscape modeling ends with the development of a Spatial Multimedia System. This study resulted in several findings. The investigation of public preferences determined dominant variables and significant variables that affect the streetscape's spatial and visual comfort aspects. This outcome guided the development scenario of 3D modeling construction and 3D simulation of each streetscape and the development of a decision-making system in the 3D spatial multimedia system. This finding also revealed the significance of the leveling strategy of user interactive advancement in the system.

Visual Evaluation of Urban Streetscape Design Supported by Multisource Data and Deep Learning

“…In the case of landscape aesthetics, there are many controversies in the industry. Often, the ambiguity of landscape aesthetics is due to the subjectivity of its definition, the lack of standardisation of its methodology, the lack of clarity in its practical application, and its own particular lack of replicability [ 4 ]. In contrast, it has become increasingly evident in the last decades that the visual aesthetic quality of landscapes is considered an important resource for the maintenance of people's psychological well-being, as well as for the conservation of biodiversity, cultural heritage, and the potential of landscapes [ 5 – 8 ].…”

“…Second, limited by TSXR 2015 data, we could not include other potential predictors of AT behavior. Hence, rigorous research design and investigation are necessary for future research to gather first-hand data on other aspects (e.g., attitude, weather/climate, and urban streetscape) (He, Zhao et al, 2021;Santosa, Nur et al, 2021;Yang, H., Zhang et al, 2020). Third, we did not consider non-linear relationships or the existence of the "threshold-value" effect (or threshold effect).…”

“…When two pairs of points meet the condition of a certain distance constraint, or when the degree of asymmetry is much smaller than the threshold of a certain distance, it can collectively reflect a kind of intrinsic symmetry in the model, due to the degree of this asymmetry. And the distance between the two points where the point pair is located is related to each other, so we use a relative threshold, where max is the highest value of the geodetic distance between all vertices, and the condition of the distance constraint can also be written by (2).…”

“…is paper analyzes the symmetry vector detection of the important research topic of the three-dimensional geometric model in the data analysis application eld [2]. Based on the highest-level three-dimensional geometric model attributes under the three-dimensional geometric model, this paper analyzes the inherent symmetry of the three-dimensional model [3].…”
