MODELLING VIETNAM’S EXPRESSWAY NETWORK

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

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

Data Management by GIS

Data fields: Expressways:1. Expressway alignment data in uniform coordinate system2. Attribute data: Length, status, developer, designer etc.3. Interchanges National highways:1. Complete road network2. Status of planned widening of NH1 which is the key North-South

artery3. Traffic count data4. Tollgate locations and details5. Traffic video Others (Reference)1. Industrial Zones 2. Airports3. Major Ports

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

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

View of Website

Website Menu

• Menu – layers can be turned on or off

Example Data for Expressway Section

Background Options – Google Map

Background Options – Google Earth

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

Status of developing traffic model

1 Network model Exists in GIS, but need to identify as nodes and links, and confirm timing of future network development

2 Traffic data 2010 data available for some national highways, but not latest

3 Administrative boundaries, population, land use data, vehicle ownership data

Available in principle

4 Studies on diversion ratios Ongoing

5 Traffic modelling Not yet started

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
