Opening the median is a facility for vehicles that will reverse direction. Along the segment Terusan Jakarta Street equipped with a median and a high number of openings with relatively low intermediate distances. Supported by location areas which are settlements, shopping centers, hospitals, schools and others so that the demand generated is quite high. The median opening condition results in high vehicle queues, especially during peak hours. HCM 2010 originates from the United States, capable of measuring the performance of urban roads at a macro level. So it was carried out supporting analysis by using a micro simulation model to produce a more detailed and representative analysis of the actual conditions. The Jakarta Canal Road section was analyzed using USHCM 2010 and modeled Microsimulation to determine the resulting performance. From the existing conditions, a scenario is designed as a solution to the problem. USHCM 2010 tends to produce worse performance due to behavioral factors that are not necessarily suitable in Indonesia. While microsimulation tends to provide better performance because not all vehicles are simulated due to limitations on the model. The distance between openings that are not close together, the wider dimension of the median opening and adjusting the direction of movement in each approach to minimize intersections that occur with the number of 2 median openings, reduce the maximum queue length by 80.75% in the morning and 84.73% in evening. Travel time averaged 28.72% in the morning and 14.98% in the evening.
