Abstract

An assessment of the effectiveness of measures undertaken to make urban road transport more sustainable requires appropriate tools to evaluate the impact of transport on air quality. For this purpose, emission inventories for the road network are prepared using suitable models. In cities without a calibrated travel demand model, the main challenge is obtaining data on traffic parameters. With this in mind, this study proposes a rapid model that enables the estimation of traffic parameters such as average speed, traffic volume, and the percentage share of individual vehicle categories. The proposed method is based on traffic measurements and the aggregation of different road classes into four cumulative categories. A comparison of results obtained from the simplified model and the travel demand model indicates satisfactory accuracy of the estimated parameters, confirming the usefulness of the proposed rapid model in emission inventory calculations. The performed calculations for PM 2.5 and NOx show that using traffic parameters derived from the rapid model, instead of those from a travel demand model, may result in an error of 15% in total emission for the traffic network.
