Afterwards, the data was analyzed by 1997 Bina Marga method and compared to the available requirements. From the analysis there were several aspects that have not met the requirements of DGH so that the alternative planning is needed.
The results of the existing alignment analysis are mean daily traffic volume of 24571 SMP / day which shows the type of class III collector road.
