Modeling of the Vehicle Passing Behavior in Two-lane Expressways
Supervisor: Kazushi SANOˇ¦Shoji MATSUMOTOˇ¦Satoshi TSUCHIYA
The performance of two lane expressway depends on the vehicle passing behavior on addition lanes. In this study, images captured from videos were analyzed, and then the car passing behavior on two lane expressways was modeled.
In order to understand the passing behavior on two lane expressways, the research took a survey to collect the date about time and position and to draw vehicle trajectory. From this survey, the occurrence of every vehicle can be approximated following the Erlang distribution. In addition, these vehicles were found that they took passing using zebra zone.
The model of the vehicle passing in behavior two lane expressways was constructed by parameters which was collected date of the investigation. This model can verify that the number of vehicle fleets, the average time required, the number of passing cars have reproducibility. With the surveyed traffic volume, extension additional lane by 50% has made average time traveled shorten by 4.4% and has increased the number of the passing cars increased by 5.5%. Furthermore, it was the most effective to extend the current additional lanes by 20%
