By having 6 intersection arms, of course there are many traffic conflicts that occur at the Cisalak I toll gate intersection, one of which is a delay in the intersection arm long so that congestion in each intersection during rush hour always occurs and coupled with the cycle time of the traffic light which takes quite a long time so the long queue occurs. The purpose of this study is to know more about the performance of the traffic. The method used is to observe directly to the research location by observing the volume of vehicles with various types, the phase current of the vehicle passing at the intersection, and the cycle time of the traffic light, and by using Vissim software as modeling and getting the results of the count. The results of the study found capacity on the Bogor Highway (Jakarta direction) with a total of 771.69 , Jalan Ir. H. Juanda is 542.92, Bogor Highway (Bogor direction) is 612.21, and Cijago / Cisalak & Natural Gas Toll Road is 538. and the value of degree of saturation in each intersection is Highway Bogor (direction Jakarta) amounting to 2.96, Jalan Ir.

The optimal time required for adequate service, fast service levels greatly affect the optimal Truck Round Time inactivities delivery. The faster the Round Time Truck, the more optimal process delivery and vice versa, from observations, the authors found a problem that one of the containers to be taken by the consignee was not in accordance with the location listed in SP2 because it had undergone a change in position that was not updated by field officers and high delivery and activities chunk of the ship. At the end of this paper, the authors conclude several dominant factors causing the length of time needed by the consignee to take the container, namely the lack of discipline of field officers to renew the latest container position, the height of Yard Occupancy Ratio (YOR) and concurrently the time of activities delivery with time off from the ship. In addition, the author also included a number of suggestions to the terminal on the factors that slowed activities delivery. It is expected that this suggestion can be useful for improvement of the conditions that already exist today.
