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

  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

  3. MINISTRY OF TRANSPORT (MOT) DIRECTORATE FOR ROADS OF VIETNAM (DRVN) VIETNAM EXPRESSWAY MANAGEMENT OFFICE (VEMO)

  4. Vietnam expressway status * Note: some sections permit motorbikes and are not strictly expressway standard

  5. HANOI DANANG HO CHI MINH CITY Vietnam Expressway Network

  6. North

  7. DANANG Central

  8. HO CHI MINH CITY South

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

  10. Data Management by GIS Data fields: • Expressways: • Expressway alignment data in uniform coordinate system • Attribute data: Length, status, developer, designer etc. • Interchanges • National highways: • Complete road network • Status of planned widening of NH1 which is the key North-South artery • Traffic count data • Tollgate locations and details • Traffic video • Others (Reference) • Industrial Zones • Airports • 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 • Data exported from GIS • Uses Google Maps as background • Google license terms (must be public access) • Data in layers which can be turned on and off by the viewer • Zoom limit applied

  13. View of Website

  14. Website Menu • Menu – layers can be turned on or off

  15. Example Data for Expressway Section

  16. Background Options – Google Map

  17. Background Options – Google Earth

  18. Expressway map + Industrial Zones

  19. Website address • The website can be seen at: http://www.vn-project.com/

  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

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

  23. Thanks to: • ADB Project: PATA 7611-VIE: Strengthening Institutional and Financial Arrangements, Operation and Maintenance, and Governance in Road Transport • Vietnam Expressway Management Office

  24. Thank you very much!
