Calibration and Validation Indonesian Highway Capacity Manual 1997 Model

Abstract

Population growth and uncontrolled use of vehicles result in changes in traffic behaviours. This has an impact on the validity of the IHCM 1997 model results when replicating traffic in the real conditions. This study aims to carry out calibration and validation IHCM 1997 signalised intersection model. Case studies are conducted at eleven signalized intersection locations in the Surakarta city. The results of study show that the IHCM 1997 method default values are not relevant to the current conditions. The traffic parameters that need to be changed in the IHCM 1997 model are passenger car equivalent (PCE) and base saturation flow (S0).
