Abstract

This paper describes the CMEM modal emission model adaptation to the fleet of the city of Maringá, Parana state, Brazil. Weighted average factors of determined emission and consumption for the city were adopted as reference parameters. These weighed factors were obtained for each PROCONVE phase through consumption and emission average factors, the latter corrected by AP-42 deterioration factors. For each Proconve phase a composite vehicle was associated. For each composite vehicle, the CMEM model parameters were adjusted to approach emission and consumption reference factors. It was observed AP42 deterioration factors tend to better represent the deterioration of the fleet, especially old vehicles. The comparison with FTP cycle results, disaggregated by phase, demonstrated more significant percentile variations than the total value of the cycle.
