THE RELATIONSHIP MODEL OF VEHICLES VOLUME AND POLLUTANTSAT SIGNALISED INTERSECTION: CASE STUDY IN FLY OVER INTERSECTION AT AP. PETTARANI RD

This study aims to model the relationship of vehicles volume and pollutants of CO, SO2, and NO2 at flyover intersection in A.P Pettarani Rd. The survey of traffic volume was done by recording the vehicles movement, at the same time measuring the pollutants by DEMS laboratory car tools. The trend analysis models performed with approaches of linear regression and polynomial models. The best of models with statistical tests of R2 . The polynomial model order-4were formed better than the linear model. The parameters value of R2 polynomial models order-4for CO and NO2 ranged from 0.921 to 0.9996, SO2 ranged from 0.684 to 0.864, The three pollutans do not exceed the ambient of air quality standard and are still in good category according to ISPU.
