Simulation of queue length on Amplas Entrance Toll before and after the ramp off development with Vissim software

In 2016 Medan City administration built on off ramp at Amplas fly over, where this ramp off directly to toll booth Amplas. The faster the time needs to get to the toll booth enables the rate of arrival vehicles that impact with increasing queue length. The purpose of this study is to know the length of the queue at Amplas toll booth before and after ramp off construction with queue theory method and vissim softwaremodelings. Data acquired by recording the activities at the research site in the form of vehicles volume. The queue length obtained from the queue method with average service time 7 seconds is 6,212 meter while the result using VISSIM software is 11,988 meter. From the VISSIM software models also obtained that the length of queue after the construction of the ramp off increases compared before the construction of ramp off, from 6,67 meter to 11,988 metre
