ABSTRACT

This study aims to develop an assessment methodology of CNS(Car Navigation System). First, this study defines the concept of benefit of travel time saving. Travel time saving benefit is defined as travel time saving times value of time of traveler who uses CNS. Subsequently, this study develops a methodology to measure travel time saving of CNS and calculates the benefit with an algorithm. In order to estimate benefit of travel time saving of CNS, this study used UTIS data which is urban transportation information system. In the analysis, we calculated unit of travel time saving in Seoul. Unit of travel time saving resulted at 60.21 seconds per person, and travel time saving benefit of CNS estimated at 3,469 million won per year. In order to examine the accuracy of the benefit, this study verified UTIS data used in this study. As a result, the error between actual travel time and UTIS travel time data is less than 10%. In addition, a paired T-test was taken to prove the accuracy of UTIS travel time data. Consequently, this study can contribute on creating formalized analysis tools to analyze the effect of CNS.
