One of the factors that contribute to the problem of traffic jams that occur along Jalan Benteng Pancasila is the presence of side barriers. Studies on the performance of Jalan Benteng Pancasila are needed to find solutions to existing problems. In this study, what was carried out was to analyze the capacity and degree of saturation in the existing and planned conditions. The analysis process was carried out using the Indonesian Highway Capacity Guidelines (IHCG) method. Based on the results of the analysis, the average traffic volume value at peak hours was 1396.90 pcu/hour, while the side resistance class was Medium. The capacity value of the Benteng Pancasila road section is 2480.41 pcu/hour, the Degree of Saturation value is 0.56, and the travel speed value is 39.0 km/hour.
