For the preparation of the advent of green growth global economic development paradigm, it is highly required to develop an integrated transportation planning model, which is able to analyse transport mode's sustainability and its environmental impacts. In this context, KRIHS-TAL(Korea Research Institute for Human Settlements-Transportation Analysis Laboratory). a prototype of GIS platform for integrated transportation planning, is developed. The model have following five features; Transparency, integrity, Experimentality, multi-discipline and Trustability, which are oriented to overcome the limitations of existing black-box style, deterministic and stand-alone planning tools.
As a first phase of the model development roadmap, the study presents basic architecture which has 11 analysing modules within 3 functional area; monitoring, Analyzing and Simulating. Using the advanced GIS technology such as layered analysis, spatial auto-correlation index like Moran's I, spatial segregation index and kriging technique, the model carried out socio-economic, transportation and environment related data monitoring and comparative analysis. Spatial and temporal analysis are also presented for the whole spectrum of various scenarios including 4 type of green growth transportation policies and land-use transportation integration in Daegu metropolitan area.
The model will have potential to perform feasibility study with the green growth criteria and traffic demand validation for the next phase. Academically, the study also developed a multi-mode variable demand traffic assignment model for the interregional travel demand analysis. It suggests two solution methods based on the excess flows and the partial linearization algorithm. The proposed algorithm is applied to the interregional network data provided by the Korean Transport Database and compared the performance with the sequential heuristic procedure where the mode choice and the traffic assignment are solved separately. It is highly expected that the development of KRIHS-TAL Ⅰ, Ⅱ, Ⅲ would play a crucial role for planning and implementing Korea's green transportation system in the near future.
