What is MMS

3D Mapping machine of road space

Enables us to produce high precision data

Impacts of MMS

MMS brought a revolutionary change in

data collection/production technology

Speed Measure longer distance in shorter period

Safety

Lesser field works, more desktop operations

Multiple use Collect 1 time, and generate data for many uses


9/34

Applications

High precision mapping of road space


10/34

Applications

Road inventory management


11/34

Applications

Pavement inspection Flood simulation

Tunnel inspection Damage level evaluation Slope face monitoring

and more


12/34

Spread MMS in Asia

Experimental operation in Bangkok

Successful result in low-altitude region

Strong expectation for new survey technology

Important findings to make MMS operational


13/34

Good Data Make City Smarter

Smart city relies on smart IT system

Well established information base is an urgent

need to manage rapidly growing Asian cities

MMS accelerate the development of citydatabase and maximise its value

without accumulated database!

It is so important to start data accumulation RIGHT NOW with right

way! Because it takes so log time to establish sufficient road databasefor road asset management, ex. Deterioration forecasting.

Improved life length

Extended life expectancy

The life expectancy of an pavement improves by solving the problem of an unusual part whichdeterioration speed is fast

As a result, the life cycle cost reduction and improve of service level is achieved

Heavy Loaded Pavement Evaluation and Assessment

Container transport has increased vehicle size and axle load

It causes critical damage to road pavements The deterioration performance can be evaluated and the optimal repair

design and pavement structure can be proposed

Type A Type B

Initial cost of type B is more expensive that of type A, but LCC

of Type B is cheaper than of type A due to the differences of

deterioration performance

New Developed PMS - Next Steps

1. Expand pavement condition surveys for the whole nation

2. Develop WebGIS based database management for PMS datasets and Pavement

condition data

3. Upgrading PMS system: WebGIS based Operation; Customization: Flowchart of

What have been done for bridge ?

Vietnamese BMS - Bridgeman


31/34

Problems with BMS ?

Developed in MS Access compatible problems.

No coding data cumbersome, large data files hard for database programming and management.

8 bit for data fields contain character (no Unicode)

require Vietnamese fonts to display the data

cannot display correctly in any browser.

Input new data to the database only through the

Bridgeman program.

No network interface Lack inspection data
