Indonesian Highway Capacity Guidance (IHCG) correction factor for signalized intersection
Civil Engineering Department, Diponegoro University, Prof. Sudharto Avenue, Semarang, Indonesia
Indonesian Highway Capacity Guidance or IHCG is a manual developed in 2014 to accommodate traffic characteristics which are no longer appropriate to the preceding manual (Indonesian Highway Capacity Manual or IHCM, established in 1997). From a preliminary study, there are still some differences between theoretical analysis (using IHCG) with the actual conditions. This study aims to obtain IHCG correction factor based on a comparison between predicted performance parameter of a signalized intersection (using IHCG) and measured data, in order to optimize IHCG development. Intersection performance parameters analyzed are the number of queue vehicles (NQ1 and NQ2), and queue length (QL). The model of the correction factor was determined with regression analysis, using DS value as the independent variable, and NQ1, NQ2, or QL differences value as the dependent variables. Implementation of the proposed correction factor of queue length on nearby intersections resulted that the corrected guidance could produce more accurate queue length against measured one by 12% deviation.
