Manipulation and Analysis

58
GIS manipulation and analysis functions are vital for decision-making and planning. These activities range from data retrieval tasks, such as selecting information based on specific criteria, to advanced analytical techniques that address complex spatial problems.One critical GIS analysis method is overlaying, which combines multiple data layers to examine impacts. For example, overlaying a river-dammed lake boundary with road networks can identify affected infrastructure. Another common...

Levels of Use of a GIS

91
Geographic Information Systems (GIS) operate across three levels of application, each representing an increasing degree of complexity: data management, analysis, and prediction. These levels reflect the expanding functionality and versatility of GIS technology in handling spatial data for diverse purposes.Data ManagementAt its foundational level, GIS serves as a tool for data management, enabling the input, storage, retrieval, and organization of spatial data. This level is often employed in...

Area of Science:

  • Urban planning and smart city development.
  • Transportation engineering and systems analysis.
  • Information and communication technology in infrastructure.

Background:

  • Urban traffic congestion is a major challenge for smart cities.
  • Intelligent transportation systems (ITS) offer solutions for integrated and sustainable traffic.
  • Understanding the determinants of ITS construction is crucial for effective implementation.

Purpose of the Study:

  • To investigate the key factors influencing urban intelligent transportation construction.
  • To develop a causal model for understanding the relationships between these factors.
  • To propose a simulation method for analyzing ITS construction dynamics.

Main Methods:

  • Literature analysis to identify 20 initial affecting variables.
  • Exploratory factor analysis on 188 expert responses to group variables.
  • Fuzzy cognitive map (FCM) based root cause analysis to establish a causal model.

Main Results:

  • The 20 variables were categorized into six dimensions: policy support (PS), traffic sector control (TSC), technical support (TS), communication foundation (CF), residents' recognition (RR), and talent quality (TQ).
  • All six dimensions positively correlate with intelligent transportation construction (ITC).
  • The strength of correlation with ITC, from strongest to weakest, is TS, CF, PS, TSC, RR, and TQ.

Conclusions:

  • Technical support and communication foundation are the most influential factors for ITS construction.
  • Policy support, traffic sector control, residents' recognition, and talent quality also play significant roles.
  • The findings provide a comprehensive understanding of ITS determinants, aiding policymakers and practitioners in improving construction efficiency.
