Abstract

The Korea Transportation Data Base (KTDB) Center in the Korea Transport Institute (KOTI) conducts the Vehicle Use Survey annually for collecting vehicle usage information of passenger cars such as vehicle travel distance, oil consumption, maintenance cost, etc. Considering the increase of smartphones, the survey was extended to mobile applications from 2013. This study was performed assuming there were differences in transport characteristics according to survey methods (paper-based and mobile-based). As a result, the average number of passages per day in the mobile survey was 2.66, while it was 2.11 for paper survey. It was analyzed that both average travel distance and time of mobile survey was smaller than paper survey. To verify the differences in the two methods, statistical test (t-test) was conducted and showed that the average travel distance and time were significantly different in two survey methods at 95% confidence level.
