In large cities as Madrid, the environmental impact of particulate matter smaller than 2.5 microns are significant. The city buses fleet in Madrid still has a significant number of Euro V diesel buses which contribute in an unknown percentage to the total amount of PN in the atmosphere. In order to assess the influence of the driving pattern of a diesel city bus along a real city bus line in the Particle Number (PN) emissions, a Diffusion Charging (DC) particle counter has been coupled to the exhaust system in series with a portable Emissions Measurement System. With this emissions measurement system, the real life PN emissions have been measured in a Euro V diesel bus in a city line of Madrid. The objective was by one side to validate the DC particle counter Pegasor for real driving emissions measurement and by the other to understand the influence of the driving pattern of city buses in a large cities as Madrid, in which the slopes and the positive acceleration from bus stops play a significant role in the transient and averaged emissions. The results were obtained in terms of PN emissions as function of average speed, positive acceleration, slope of the street and load of the bus in other to establish correlations
