Applying of City Information Modeling (CIM) Technology; a new approach in smart urban management (Case study: Ka lad, Tehran City

The pace of technology development in the world and the emergence of smart software and applications are indicative of the development of technology in the field of science. In this way, the relationship between urban design knowledge and urban planning with technology should not be ignored. 3D visualization tools are used to create high-level designs around the world. Urban three-dimensional models are generally generated to describe the current situation, and at a higher level, three-dimensional urban models can be well used in simulation for topics related to various types of urban management, including crisis management. Having smart city management depends on the use of smart executive tools in different dimensions of the city. The Procedural Modeling approach and its tools are one of these technologies, that by using it, dynamic and automatic feedback can be created throughout the design process and flexible and smart scenarios can be designed and programmed. With a practical approach, this paper first introduces Procedural Modeling to design, modeling and simulation by using the CityEngine software. In order to demonstrate and present the use of this smart simulation technique, the visualization of the current situation for a part of the Kalad neighborhood of Tehran city, will be done in four basic steps; The first step is to gather all the necessary information and attributes of the buildingsto create a database for modeling along with taking pictures of the buildings facades. The second step is to write the CGA rule file and the next step is to create a three-dimensional simulated model in the CityEngine software by using algorithms and written code. Finally, the final result of the simulated three-dimensional model is published as a web-based output. Since these codes are textual, they can be changed and developed in the future
