Abstract

This paper intends to present the existing methods utilised to assess the emission impacts of ITS emphasising the lacks, which risk compromising the goodness of the results. The importance of the reliability of transport data is demonstrated in this work. It was found that the emission factors calculated by the model vary substantially when the travel-related inputs to the model are varied within the usual ranges of accuracy and precision expected with the current state of the practice in transport. In addition, the average emissions model do not enable to reliably evaluate operational improvements that smooth traffic flow such as ramp metering, signal co-ordination and many ITS strategies. A proposal is presented to manage the actual needs of precision under the viewpoint of "sample enumeration" technique. For the covering abstract see ITRD E114174.
