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.
