Passenger Car Equivalent (PCE) is expected to be very accurate because it is very important in determining the capacity, degree of saturation, and handling of unsignalized intersections. Several methods have been used to estimate the PCE value, but based on the literature review, it is stated that the occupancy time method and the speed method are the most applicable for the unsignalized intersection conditions. This study aims to determine the most appropriate PCE value by comparing the occupancy time method and the speed method. To determine the most appropriate method in calculating the PCE of the unsignalized intersection, the calculation of the value of capacity and degree of saturation based on the method of speed and occupancy time is compared with the PCE value of MKJI. The result shows that the most suitable PCE value for unsigned intersections is the speed method. The recommended changes in the value of PCE are unmotorized vehicle PCE = 0.45, motorcycle PCE = 0.17, and large vehicle PCE = 2.2. Determining the correct PCE value is expected to provide accurate intersection performance results and determination of intersection problems.
