A Driving Pattern Survey in City of Seoul for Vehicle Emissions Control 982896

A computer aided test system, which is called MOde Survey System (MOSS), is newly developed to evaluate a driving pattern and traffic flow in Seoul, Korea. This system is designed for the people who work on vehicle emissions and energy more quantitatively with the aim of being cost-effective and easy-to-use.

Compared to currently-existing Test and Measurement Systems, MOSS is designed and developed for a specific goal with a couple of unique features. These features are:

1)
To be able to be used as either a stand alone system like a data logging system or a real-time processing system with a PC to easily visualize vehicle performances and traffic information during the test.
2)
To provide a statistical analysis program for easy use to analyze of driving pattern and traffic situation with logged test data files.

The test results show that about 35% of the total travelling time is the stationary time, the vehicle runs under 100rpm for around 50% of the total travelling time, and drivers shift the gear about 2 times per minute during driving in Seoul
