Abstract

Abstract- As electronic toll collection systems based on 5.8 GHz
dedicated short-range communications (DSRC) have become popular,
real-life travel time collection via DSRC systems is attracting more
interest. The DSRC system, composed of an on-board unit and a roadside
unit, has the advantage of gathering section travel times directly.
However, outliers resulting from vehicles entering or exiting a section,
parking activities, and so on have been considered a critical hurdle to
be overcome in estimating reliable travel times. In this study, a modified
Ferguson test is applied to clean DSRC probe data on a signalized rural
highway in Korea. The proposed method was tested with 24-h block
real-world data, indicating satisfactory results
