Recently, automobile has been developed as a fusion technology product with many electronic parts and telematics equipments and many ECUs. Automobiles are becoming more intelligent and safe vehicles, assemblies of advanced technology by customers’ demand. A study on the natural driving pattern and driver"s response in various traffic and road condition is essential to develop the driver friendly intelligent vehicle. We introduced the field operational test (FOT) database, which could be used as driving and road conditions collection for researches about driver friendly intelligent system, Human Vehicle Interface(HVI) system and economic driver model and so on, which has been built by Korea Automotive Technology Institute(KATECH) from 2 years ago. Also, we compared Korean and American driving characteristics based on FOT database. American driving data came from UMTRI(University of Michigan Transportation Research Institute) RDCW(road departure crash warning system) FOT database. We showed macroscopic observation results about driving tendency of both database in this paper and we will present detail analysis results in the close future.

The most people have some representative prejudices when they are facing women drivers while driving. They tend to associate with female drivers as interrupters who impede the flow of the road. For example, the people who drive too slowly alone, drivers who have frequent sudden stop and a quick start and inexperienced people with changing lanes. In this paper, we have studied deceleration characteristics which is one of drivers' traits according to drivers' gender when they driving on the highway for investigating the truth. For experiments, we recruited twenty men and twenty women patients who are 30~40 years old. Highway is selected as a test course to reduce to a minimum impact from environment Brake Act signals that is transported from vehicles are used to analyze and same a highway and a vehicle are used at the same time. About 20 minutes before starting the test have been adapted to the drivers to get used a test vehicle. Through the result of this study, we would like to identify male and female drivers' deceleration characteristics and reconsider preconceptions about women drives that most people have.

This paper is research about proactive safety and we have measured driver"s real time position of eye and head by using a camera settled in front of operator (driver) and a eye tracker equipment. Collected data were used to analyze a correlation between driver’s career and gender and its effect on driver’s behavior. Moreover, By calculating standard deviation figure (σ) of driver’s head behavior studied to represent how stable behavior depend on features driver has. This study results will be used to concrete an accident preventative education and be utilized as basic material for design system such as each different warning process following driver’s feature.

In this study, the relationship between how to drive diesel vehicles and fuel economy have been demonstrated when driving in the city. A multiple drivers driving in the general city, the data were collected for 1 hour. And the most common driving distance and stoppage time and stopping times of the information was extracted. The experiments were carried out based on the results on proving ground. Experimental parameter were selected in constant distance, deceleration distance, acceleration, etc. And in certain situations, the most efficient results are obtained. In conclusion, the amount of the possible effects could be obtained when the results apply to normal driving in the city.
