Abstract
CAL3QHC (Caline 3 with Queueing Hot Spot Calculations) is a microcomputer-based model to predict carbon monoxide (CO) or other inert pollutant concentrations from motor vehicles at roadway intersections. The calibration had been conducted at Jl. Juanda-Diponegoro-Sulanjana intersection, which has high traffic volumes. The sampling was done for 6 times, each between 12-24 hours. The total number of sample used for calibration computations are 36 and randomly selected from each series of sampling. According to the research result shows a calibration curve of y = 1,2018x – 0,3477 where x is representing the result of model computation. Meanwhile the statistical analysis gives a correlation coefficient (r) of 0,74, which deals with the 1% level of significance degree (r) in 0,424.
