Planning Department Agreement No. CE 60/2005 (TP) Land Use Planning for the Closed Area – Feasibility Study Appendix C – Transport Modelling Approach and Validation A Transport Modelling Approach and Validation A.1 Proposed Area of Influence The Area of Influence (AOI) of the traffic model is illustrated in Figure A1 . The AOI adopts the Study Area defined in the Study Brief as the basis with extension to cover not only the proposed NDAs at Kwu Tung North, Fanling North, Ping Che and Ta Kwu Ling, but also the New Territories to the north of ATC Screenline R-R, including Tai Po, Sheung Shui/ Fanling, Tuen Mun, Yuen Long and Tin Shui Wai districts. To examine the additional traffic which will distribute to all over the territory, other strategic highways providing main accesses for the proposed NDAs such as Fanling Highway, Tolo Highway, Tuen Mun Road, Tai Lam Tunnel, Yuen Long Highway and San Tin Highway etc. are covered within the AOI. A.2 Strategic Model Preparation Arup’s in-house territory transport model was developed using EMME software which comprises a traditional 4-stage model and is compatible with Transport Department’s Enhanced Comprehensive Transport Study – 3 (ECTS3) model. It has been well-validated to year 2005 by territory-wide cordons and screenlines and major corridors including Tolo Highway. It is hence recommended to adopt this model as a basis and update it using the latest available planning data and land use data for this study. With the availability of the 2006-based Territorial Population and Employment Data Matrices (TPEDM) land use data released and revised by Planning Department (PlanD) in May and July 2008 respectively, the base year model was developed for year 2006 and it was validated to 2006 traffic condition. The model input data for base year model setup is described in the following sections: A.2.1 Territorial Planning Data The 2006-based Territorial Population and Employment Data Matrices (TPEDM) summarises the land use data for base year 2006 and was provided by Planning Department. The key data is summarised in Table 1 .

In accordance with the webpage information of Highways Department and rail operators, the following highway and railway updates were incorporated into the strategic model for this study. Highway • Castle Peak Road Improvement between Area 2 and Sham Tseng, Tsuen Wan • Widening of Yuen Long Highway between Lam Tei and Shap Pat Heung Interchange Railway • Opening of AsiaWorld-Expo Station Z:\Report\041 Draft Final Report\Final Report\Appendix C.doc Page C-2 Ove Arup & Partners Hong Kong Ltd February 2010 Planning Department Agreement No. CE 60/2005 (TP) Land Use Planning for the Closed Area – Feasibility Study Appendix C – Transport Modelling Approach and Validation A.2.3 Economic Growth According to the C&SD’s information released, the year-on-year growth in Gross Domestic Product (GDP) in real terms for base year 2006 was 7.0%.
