1. Presented by: Ms. Le Thi Lan Bizdev.asia MODELLING VIETNAM’S EXPRESSWAY NETWORK

2. Summary Presentation by consultant Recently worked on an ADB assignment supporting the Vietnam Expressway Management Office Good progress with a GIS Next step is traffic modelling Joined this seminar to tell you about our progress using GIS for a national network, and to learn about traffic modelling

9. Data Management by GIS Objective: 1.Management of data on expressway alignments, sections, interchanges, toll gates, traffic volumes, implementation status, numbering system, parties involved etc. 2.Single source of data available to decision makers, Ministry staff 3.Publishing GIS data through a website shares information with potential investors, consultants carrying out studies, Government staff, the media and the public 4.The GIS network model potentially forms a basis for traffic modelling

10. Data Management by GIS Data fields:  Expressways: 1.Expressway alignment data in uniform coordinate system 2.Attribute data: Length, status, developer, designer etc. 3.Interchanges  National highways: 1.Complete road network 2.Status of planned widening of NH1 which is the key North-South artery 3.Traffic count data 4.Tollgate locations and details 5.Traffic video  Others (Reference) 1.Industrial Zones 2.Airports 3.Major Ports

11. Challenges in data collection No existing system for management of expressway data Data held by multiple sources (Ministry, developers, consultants etc.) Data often in spreadsheets (not geo-referenced), or in various coordinate systems Data changes (alignment, ICs etc.) during project life cycle from masterplan to detailed design Implementation schedule is continuously changing

12. Website Overview 1.Data exported from GIS 2.Uses Google Maps as background 3.Google license terms (must be public access) 4.Data in layers which can be turned on and off by the viewer 5.Zoom limit applied

20. An expressway traffic model Previously traffic models in Vietnam have been created by JICA projects using STRADA, but have some disadvantages -Software is not in general use by international consultants -Reliability / credibility of model and results -Very few people can use / have access to data VEMO wants to be able to own and operate it’s own model for scenario studies, revenue analysis, feasibility study

21. Status of developing traffic model 1Network modelExists in GIS, but need to identify as nodes and links, and confirm timing of future network development 2Traffic data2010 data available for some national highways, but not latest 3Administrative boundaries, population, land use data, vehicle ownership data Available in principle 4Studies on diversion ratiosOngoing 5Traffic modellingNot yet started

22. Next steps 1.Develop rough traffic model 2.Continue to refine the model 3.Carry out in-house studies 4.Issue the model to investors / consultants as a base model in their detailed studies 5.Use the model to review feasibility study results 6.Use the model to monitor forecast and actual diversion ratios / traffic volume / revenues
