Abstract

In recent years, there has been a lot of international research on ITS. Research on various traffic systems, such as VICS, has also been carried out in Japan. Moreover, travel time information is important for traffic control systems. If a toll collection system is adopted, we can calculate travel-time from toll collection system data. Little attention has been given to this because of the following problems. Unusual-data removal is difficult. (In this paper, unusual data means data deviating from the main distribution of travel time data.) When there is a small number of data, it is difficult to calculate an appropriate travel time. Japanese expressways have service areas and rest areas. Thus, data for vehicles which have stopped for a long time in a service area or rest area are considered unusual data. Data for extremely short travel times, such as by motorbikes, are also considered to be unusual data. It is important to remove these unusual data. Therefore, this research proposes a method of calculating travel time information using data obtained from toll collection systems.
