Management and Enhancement of Livable Urban Streetscape through the Development of the 3D Spatial Multimedia System A Case Study of Provincial Street Corridors in Malang, Indonesia

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.
