Today, many motorists want a smooth ride. Toll roads are considered freeways that can provide smoothness, comfort, and safety to their users. Therefore, we conducted research that aims to create a system that regulates toll road payment queues. This is done so that the toll road queue can run more smoothly, effectively, and efficiently in the system. In this study, we used a discrete simulation model by designing a simulation system and made two improvements using the arena simulation application. This makes it easier for us to analyze the designed simulation. From the research with two improvements. Based on the table and the results of the histogram comparison of waiting times on the GTO Kalimalang 2 queuing system, the waiting time on the actual system is 2.29303595 minutes, and on the proposed system 1 the waiting time is 1.68561362 minutes, and in the proposed system 2 the waiting time is 1.47913723 minutes. So, the largest waiting time is in the actual system while the smallest waiting time is in the proposed system 2. This indicates that the system proposed in the second improvement has better performance than the first proposed improvement and the actual system performance.
