| Abstract | This study aims to develop the computer package (MCAL3) to predict the carbon monoxide (CO) emissions in Bangkok. The MCAL3 (Modified CAL3QHC), a graphical user interface microcomputer-based model, is the modified version of the US. Environmental Protection Agency (EPA.) model called CAL3QHC. MCAL3 is developed to be the user friendly interface by using visual basic language and also to be compatible to estimate the CO emission at any intersection in Bangkok. An intersection in Bangkok (Ladprao-Chokechai4 intersection) was selected to validate the developed package by comparing the results obtained from the program and with that of the Pollution Control Department, Thailand (PCD)'s actual measurement. It was known that results obtained by the package are nearly the same as PCD's measurements. Furthermore, the statistical test also revealed that there are no significant different between the predicted and actual observed concentrations. To demonstrate the applications of developed package, MCAL3 is then used to test several traffic policies through the determination of CO in Bangkok. It was fow1d that the current police practice of controlling the traffic signals with the unreasonable and excessive cycle lengths at the intersection would yield higher CO concentrations. Furthermore, other traffic policies such as parking restriction along roadsides, implementation of bus lanes could reduce CO concentrations resulted from the increasing in saturation flow rates. On the other hand, increasing of free flow speeds through improvement of physical dimensions of intersections such as providing large lateral clearance or roadway width could also help reducing CO concentrations. |
