2  Background  Model Review  Model Function  Model Structure  Transportation System  Model Interface  Model Output  GIS Display

3 New Taipei City (29) Taipei (12) Guishan Town(1) Study Area -- Taipei Urban  County: Taipei、NewTaipei & Gishan Town  Town:42  Area: KM 2  Population:6.71million people 3

4  Taipei Mass Rapid Transit System(refers to Taipei MRT)  the First & the Largest MRT System in Taiwan  108 Station  Legth:116.8km

5 TRTS-I TRTS-II TRTS-III TRTS-IV DOTS-I DOTS-II year Update Data Upgrade software and display system 5  TRTSI, II  Aggregate Sequential Travel Demand Model  Software: Transport(Highway) & Tranplan(PT)  TRTS III  Aggregate Sequential Travel Demand Model  Software: Transport & Tranplan  Main for passenger transportation system, for the MRT planning  DOTS-I,II  Base on TRTS III,Data Update  Software: Transport & Tranplan, Access 97 (DOTS-II Database), ArcView(for GIS Display) 2011~2012

6 6 Combined with GIS & Database Transit DataBase,GIS Display Extension Interface Economic benefits、Energy consumption Provide meso and micro analysis software integration interface Small regional network analysis, intersection signal, centriod line Long-term transport planning Transportation Demand Analysis, Policy evaluation Friendly User Interface Development of the Windows operating interface, enhance friendly User Interface Model Function

7  Four Main Model  Socio-Economic Prediction model─estimated future year Socio-Economic Data  Supply Model-Compute the Initial skim and parameter for Demand Model  Demand Model-the main model of TRTS IV, with four transportation planning step. ▪ Sub-Demand Model – AM/PM/Non-Peak Analysis ▪ Peak Sperading Model- AM/PMPeak Hour Analysis ▪ Daily Demand Model- Sum of All Sub-Demand Model  Evaluation Parameter Model- compute some economic paramter like VTT, VKT
