Economy in Yogyakarta is growing more from year to year. One of the most popular business is culinary. One of them is Tempo Gelato. Build the restaurant having many effect for traffic around the Tempo Gelato location. Need to do microsimulation to decided the effect of traffic around the location with modelling. Therefore for this research methodology modelling method used PTV. Vissim 9 in intersection and road segment at Taman Siswa street based on traffic survey counting. For the result existing condition of Taman Siswa gets the result long queues average is 35 m, delays is 94 second, and LOS F. For the road segment get the result long queues is 1.02 m, delays is 9 second, and LOS A. For the 2018 operational condition Taman Siswa intersection get the result long queues is 39 m, delays is 82.82 second, and LOS F. For the road segment get the result long queues is 1.26 m, delays is 8.1 second, and LOS A. After give the alternative to make the road become one way road, Taman Siswa intersection get the result long queues is 12.12 m, delays is 58.77 second, and LOS E. For road segment get the result long queues is 3.25 m, delays is 6.18 second, and LOS A. The service level at road segment increase from F to E.
