Research on Establishment of a Standard of Traffic Impact Assessment with Integrated Database System
Planning support systems, such as geographical information system (GIS) and traffic flow simulation models, are widely in use in recent urban planning research. In this paper we propose a method to apply traffic impact assessment (TIA) to large-scale, commercial developments. In TIA research we often encounter the problem of increasing amount of data that is necessary for detailed investigation and analysis, as the scale of commercial developments become larger and more complex. As a result, TIA presents two problems. The first problem is the difficulty of data acquisition. The second problem is the reliability of data. As a solution, we developed an integrated database system.
