Verification of port container terminal implementing carrying-in and out reservation of CONPAS function by discrete simulation

Abstract

At port container terminals, there's a significant traffic jam of outbound trailers at the entrance gate. To address this issue, the Port and Harbor Bureau of the Ministry of Land, Infrastructure, Transport, and Tourism has introduced a system called CONPAS (Container Fast Pass), which allows for reservations when carrying-in and out containers at these terminals. The primary goal is to reduce trailer wait times. In this study, we developed a discrete system simulator specifically for terminals that have implemented the carrying-in and out reservation function. Using this simulator, we evaluated the effectiveness of this reservation system. Additionally, we investigated how various factors, such as the percentage of trailers utilizing the reservation system and the conditions under which users access priority lanes, impact trailer wait times at different ports.
