The Indonesian Highway Capacity Manual (IHCM) and previous research have not adopted motorcycle behavior to determine the efficiency of passenger cars in synergy. This study aims to assess PCE based on the behavior of motorcycles in synergy with and without Exclusive Stopping Space for Motorcycles (ESSM). The synergy reservoir's location was a junction with a high motorcycle volume, low side obstacles, and traffic characteristics at an approach width of 3 meters, 5 meters, and 7 meters in Denpasar City. The survey method divides the lane virtually, the size of a motorcycle to determine the headway in the field. At the same time, the saturated flow was analyzed using the discharge headway method of both normal distributed data and log normal. Linear regression analysis was used to determine PCE based on motorcycle behavior on synergy junctions both with ESSM and without ESSM. Based on motorcycle behavior, the highest PCE value is obtained beside flow behavior (0.1-1.2) and the lowest in front behavior of the stop line (0.06-0.8). In determining PCE, it is recommended to adopt the motorcycle’s behavior.

Introduction Passenger Car Equivalency (PCE) is the conversion factor of various types of vehicles with light vehicles into reference or becomes the standard where the PCE of light vehicles (LV) is 1. PCE is a unit to convert the unit of the flow of traffic flow units from vehicles/hours into PCU/hour, while the passenger cars unit (PCU) is a unit for traffic flow where the flow of various types of light vehicles (including passenger cars) use the frequency of passenger cars equivalency (PCE) [1]. Traffic flow occurs in the field varies; whereas, the flow of traffic is described as several vehicles on various types and properties form a traffic flow. Each type of vehicle has a diverse geometric, size, and acceleration to create different traffic characteristics for each composition. The Equivalency value of Passenger Cars (PCE) for signalized intersection based on IHCM [1] can be seen in Table 1. Table 1.
