APPLICATION OF MULTI-AGENT SYSTEM IN URBAN RENEWAL DESIGN

Abstract

As cities expand, many old towns face the threat of being renovated or demolished. In recent years, the drawbacks of extensive urban renewal have become increasingly apparent, and the focus of urban development is gradually shifting from efficiency to quality. This study aims to combine urban renewal with Multi-Agent System (MAS) to address the dilemma between efficiency and quality in urban renewal. Modern design disciplines frequently use more effective intelligent technologies and complicated computers due to the advancement of information technology. In order to provide clients additional value-added services, the industry for urban and architectural design has been transformed attributable to the research of intelligent technologies. While computer design techniques have achieved success, there is still untapped potential for MAS in urban and architectural design. The study found that algorithm models based on graph theory, topology, and shortest path principles neglect the influence of internal states and visual features on pedestrian activity, resulting in lower simulation accuracy. Although incorporating internal states and visual features into the core of the algorithm has further improved simulation accuracy, the model operates in a 3D environment with lower efficiency. To address the problems of insufficient simulation accuracy and low efficiency, this study proposes a dynamic pedestrian activity model based on a MAS and incorporating visual features. The model simulates pedestrian daily activity paths using pheromones and virtual sensors as the core, and it was found that using Visibility Graph Analysis (VGA) can accurately divide pheromones in the environment, thus obtaining more accurate simulation results. Subsequently, based on the optimized pedestrian model's agent activity rules and dynamic pheromone theory, a model for automatically generating road paving in urban renewal projects was developed, and the generated results were verified for their rationality through design practice. This technology can effectively promote urban renewal and the preservation of historic neighborhoods, providing technical support for achieving sustainable urban development.
