Comprehensive Exploration and Analysis of CityEngine as a Novel Tool for Smart Urban Planning and Design (Case Study: Narmak Neighborhood, Tehran)

The rapid growth of urbanization and the increasing complexities of urban management have highlighted the need for innovative and efficient tools in the field of urban planning and design. Today's urban planning and desgin community, in the information era, requires novel technology-driven systems to make better decisions and achieve better results in the shortest possible time. CityEngine, as a city-scale data-driven smart system, offers significant potential for improving the quality of urban planning and design. This applied research aims to introduce and comprehensively analyze CityEngine in the context of urban planning and design. The Narmak neighborhood of Tehran is selected as a case study. Data were collected using various methods, including document review, field survey, and spatial data analysis. The findings of the study show that CityEngine can be effectively applied in various aspects of urban planning and design, including: Dynamic 3D visualization of urban space (detailed and comprehensive urban plans, zoning and design control planning, 3D cadastral planning, environmental planning and design, strategic urban planning), Real-time reporting of urban data for quantitative analysis, Evaluation and management of the urban environment along with providing a communication platform for public participation, Integration with other relevant urban application software. The results of this research demonstrate that CityEngine, as a novel and efficient tool in the field of urban planning and design, can contribute to creating smart and sustainable cities. In CityEngine for urban planning and design modeling, the following four main steps are presented in the paper: (1) data preparation and processing (2) Classification of urban elements (3) Creating and defining rules (4) Generating a model and modifying it. Comprehensively and deeply, it can be acknowledged that CityEngine for; The integration of scattered urban data and the creation of a smart two- and three-dimensional database, the reduction and intelligent monitoring of urban violations through the modeling of urban information (zoning regulations, density, etc.), increasing the speed and less waste of time in planning, designing and managing urban projects, increasing the role of citizens in solving and participating in urban issues through online sharing of plans on the web, the ability to intelligently model all types of elements and objects in the city, including buildings, streets, vegetation, urban furniture, etc., help in integrated management city through the creation of manageable dashboards and real-time control, access to the information of smart 3D urban elements with the ability to view all features in 3D as well as update information, increase the image of the city with interactive 3D visualization to help understand the urban environment for Managers and citizens, production of past, present and future models of cities in order to observe and compare urban changes, designing city redevelopment scenarios and examining the effects of each scenario in real-time, analyzing the three-dimensional view of the city in order to accurately examine the effects of urban visual permeability, City simulation based on real geographic information system (GIS) data to improve 3D city perception, it is effective and useful.
