Research purposes is to determine level of service that occurs in traffic flow, to obtain this aim PKJI 2014 is used. This research obtains average travel time for vehicles making a U-Turn, length of queue when making a U-Turn, average travel time average number of vehicles disturbed and not disturbed by U-Turns and knowing level of service on that road section. From data processing it can be concluded that peak hour vehicle speeds are slower than non-peak hour vehicle speeds due to high traffic flow. Meanwhile, waiting time when a vehicle is about to turn around, during peak hours vehicles wait longer than during non-peak hours because volume of vehicles is denser during peak hours. Average queue length in opposite direction during peak hours is longer than during non-peak hours due to the density of vehicles during peak hours, it can be concluded that level of service C.
