TY - JFULL AU - Ahmad Munawar PY - 2009/6/ TI - The Use of KREISIG Computer Simulation Program to Optimize Signalized Roundabout T2 - International Journal of Computer and Information Engineering SP - 1346 EP - 1350 VL - 3 SN - 1307-6892 UR - https://publications.waset.org/pdf/376 PU - World Academy of Science, Engineering and Technology NX - Open Science Index 29, 2009 N2 - KREISIG is a computer simulation program, firstly developed by Munawar (1994) in Germany to optimize signalized roundabout. The traffic movement is based on the car following theory. Turbine method has been implemented for signal setting. The program has then been further developed in Indonesia to meet the traffic characteristics in Indonesia by adjusting the sensitivity of the drivers. Trial and error method has been implemented to adjust the saturation flow. The saturation flow output has also been compared to the calculation method according to 1997 Indonesian Highway Capacity Manual. It has then been implemented to optimize signalized roundabout at Kleringan roundabout in Malioboro area, Yogyakarta, Indonesia. It is found that this method can optimize the signal setting of this roundabout. Therefore, it is recommended to use this program to optimize signalized roundabout. ER -
