One of the specific goals of the PhD is to progress on the microscale emission model used to calculate the traffic emissions in hot-spots. In order to adapt this model to the specifications of the Madrid?s vehicle fleet characteristics, it is essential to collaborate with other research groups and experts that have developed specific traffic emission models. This is the reason to propose this research stay in the University of Queensland (Australia) in collaboration with Dr. Robin Smit who has developed a microscale traffic emission model for Australia (P?P) that in addition to his extensive knowledge about traffic emission models is a recognized standing expert in this research area. During the 3 month research stay this model (P?P) will be studied and compared with the European instantaneous emission model PHEM-light. The aim of this comparison is to establish the fundamental differences between models and the relevance of the different parameters involved in a detailed emission calculation to be able to introduce them for the calculation of the emission in hot-spots in Madrid. In this stay we will advance in the understanding and analysis of the two emission models, we will approach their comparison and analyse the results what fits well also with the interests of the host group. This research stay specifically related to the need to improve our knowledge of microscale emission estimation methodologies and models to identify options to successfully integrate them in urban air quality modelling tools. One of the main goals of the investigation is to deepen into the basis of traffic emission models in order to better the methodology of emission calculation applied to the city of Madrid that constitutes the main case study for this PhD Thesis. For this purpose two modal emission models have been studied and the results have been compared in order to define the main variables involved in traffic emission calculation. In modal models emission rates are a function of specific engine or vehicle operating modes at the highest resolution (one to several seconds). In this sense, main vehicle category, vehicle class, vehicle power, vehicle mass (and loading), road grade or engine capacity are going to be studied.
