Abstract :Pollutants from combustion engine powered public transportation are showing great importance in terms of air quality, human being health and also the global warming. The amount of fuel consumed during transportation is another factor that should be taken in to account because of economic aspects. In this context, a part of one of the world’s biggest public transportation axle – Istanbul Metrobus public transportation system – which is using a dedicated line is analyzed via using on board emission measurement system and onboard fuel consumption metering devices. The relevant controller area network data was collected during cruises. The fuel consumption and emissions results are analyzed regarding to cruise statistical data, driving modes, road gradient and vehicle specific power data and per passenger statistic. A strong correlation between vehicle specific power and fuel consumption and emissions is shown. The effect of acceleration and velocity are analyzed. Fuel consumption and emission data obtained regarding to the topography indicated that, topography should be used with vehicle properties in public transportation planning. Also it was evaluated that the portable emission measurement systems and mobile fuel consumption measurements can be a part of engine calibration development for environmentally friendly and economic public transportation.Keywords : Driving modes, Fuel consumption, Real driving emissions, Road grade, Vehicle specific power
