Özet
In this study, the change of vehicle emissions in four signalized intersections and along the five streets in Millet Boulevard of Kirikkale are modeled according to scenarios of interrupted flow and green (flow) wave. For this purpose, volumes and traveling speeds along the streets and waiting times (delay) in intersections are obtained by vehicle counting methods in these locations. Vehicle based emissions for present interrupted conditions are determined. Afterwards, to examine the effect of green wave, reductions in vehicle emissions are modeled for 50 km/h constant speed and stopping in only one signalized intersection case. It was observed that green wave scenario reduced the vehicle emissions by 74.0 % in general. It was also observed that by green wave scenario, emissions in streets were increased by 3.8 % while emissions during stopping and starting in intersections were decreased by 18.2 % and 22.6 %, respectively. The most important advantage of green wave scenario is that CO pollutant, the biggest share among pollutants, were decreased by 76.8 %.
