- Abstract:
- In order to estimate vehicles inventory in high resolution at a mieroseopie seale region, the MOVESmodel of US new version was introdueed and the sensitivity of three tralfie condiions parameters was analyzedTaking a typieal signal interseetion as research objeet, the operalion modes relleeting vehieles running charaeteristies in interseetion were gained through field measurement and statistieal analysis. In eonsideration of timing weight in the different direetions, the PM2.5s and CO inventories of typical intersection were ealeulated byMOVES model. Lastly, the effieieney of compressed nalural gas ( CNG ) in the reduetion of PM2.5 s and CO wasmodeled when the buses conventional fuel was replaced by the altemative fuel (CNG). The results show that.the traffie emission evaluation based on operating mode can better relleet the realistie vehicles" operation na.ture more, and ealeulate out more preeise values. In the case study, the emission inventories of PM2.5 s and CO in the interseetion region were redueed by 66%6 and 596 respectively after the bus fuel of CNG was pulinto use.
