<![CDATA[Transportation is the movement or movement of people or goods from one place to another. Accumulation of vehicles that occurs will cause problems in the transportation movement system, such as delays or congestion. To find out the impact of U-turn facilities on the performance of national roads (primary collectors), it is necessary to carry out the evacuation, analysis of road performance and turnaround performance in order to obtain alternative solutions to problems to reduce traffic conflicts at the turnaround facility. Evaluation and analysis were carried out based on PJKI 2014 and PPPB 2005. The data used were obtained from a survey on March 17, 2020. The results obtained by using PKJI 2014 and PPPB 2005 are the degree of saturation in the north (Malang-Surabaya) 0.46 <0.75 and the degree of saturation towards the south (Surabaya-Malang) 0.72 <0.75. The travel speed in the north (Malang-Surabaya) is 59 km / hour and the travel speed in the south (Surabaya-Malang) is 52 km / hour. The highest turnaround performance occurred at the turnaround in front of the Mondoroko Singosari gas station with a volume of 133 Skr / hour, a queue length of 19.8 m and a delay of 180 seconds. The alternative chosen was to close several return rounds, the result of the alternative was a reduction in the number of return facilities from 12 points to 6 points, a decrease in queue length and a delay at a high-performance turn-around facility, namely a return turn in front of the Mondoroko Singosari gas station with a volume of 133 Skr. / hour, the queue length is 19.8 m and a delay of 180 seconds. After the turnaround was closed and merged into one with the reverse turn in front of Marsudi Waluyo Singosari Hospital and SMKN 1 Singosari, the volume was found to be 66 cur / hour, queue length 15.75 m and a delay of 53 seconds.]]>
